Byzantium: The Decline and Fall (2) by John Julius Norwich (1995)

This is a review of the second half of the third volume in John Julius Norwich’s weighty and famous three-volume history of the Byzantine Empire, from the founding of Constantinople in 330 to the fall of the same city to the Ottoman Turks in 1453.

The third volume covers the period from the catastrophic Battle of Manzikert of 1071 in which the Byzantine army was massacred by the new power in the Middle East, the Seljuk Turks, through to the final triumph of the Ottoman Turks and the miserable fall of the city.

It is a long, miserable and frequently appalling book to read. It took a big effort to get over the emotional trauma of reading about the sack of Constantinople by the Fourth Crusaders in 1204, so traumatic I devoted a detailed blog post to it.

Byzantium: The Decline and Fall contains so much brutality, cruelty, violence, so much destruction, rape and sending into slavery that it is hard to process and hard to cope with, emotionally.

As mentioned in my review of the first half, it depicts a world of unending conflict, in which all nations, rulers, emperors, kings, princes, khans, sultans, emirs and warlords are unceasingly engaged in endless conflict with each other, in which no treaties last, no peace endures, and each spring armies are mustered the length and breadth of Europe and Asia, on that year’s campaign of war and conquest.


Key events

1202 Fourth Crusade assembled at Venice. 1204 The Fourth Crusade captures Constantinople. A Latin Empire of Constantinople is formed, with other territories parcelled out to crusader lords and upstart Greeks asserting new Byzantine ‘successor states’.

1209 – 1229 The Albigensian Crusade against heretics in the south of France.

1243 The Battle of Köse Dağ in which the invading Mongols devastate the Seljuk Turks. The Turks never recover, but disintegrate into a host of emirates and small successor states. One of the smallest of these, in north-west Anatolia, would be ruled by Othman who would become the semi-legendary founder of the Ottoman Empire.

1261 Emperor Michael VIII Palaeologus recaptures Constantinople, not in a battle but almost by accident when the main Latin army is away.

1274 Union of Lyon – at the Second Church Council of Lyon the fourteenth ecumenical council of the Catholic Church the Byzantine emperor Michael VIII made various pladges to reunite the Eastern church with the Western i.e. to submit to papal power and to change rituals and wordings to agree with the Latin rite. This was a bid to gain help from the pope and Latin nations but the Greek population and most of the clergy rejected it, and it was later repudiated by Michael’s successor, Andronicus II.

1282 The Sicilian Vespers – the Norman rulers of Sicily were a persistent threat to Constantinople, repeatedly mounting large expeditions to cross the Balkans and attack the city. The Sicilian Vespers was a rebellion of the native population of Sicily against their arrogant French overlords, which massacred them and for a generation neutralised that threat.

1291 The Fall of Acre, the last Crusader kingdom of Outremer.

1299 date traditionally given for the founding of the Ottoman Empire.

1354 The Ottoman Turks capture Gallipoli on the northern, European shore of the Bosphorus and henceforth use it as a bridgehead into the Balkans.

1389 After victory at the Battle of Kosovo (15 June) the Ottoman Turks take over most of the Balkans, depriving Constantinople of agricultural land and manpower.

1402 Tamburlaine devastates the Othman Turkish army at the Battle of the Chubuk Plain. If he had stayed and conquered more of Anatolia he might have wiped out Ottoman Rule but he ceased his Western campaign and turned East where he died the next year, leaving the Ottomans to regroup and renew their threat against Constantinople.

1453 May 29 – Fall of Constantinople Sultan Mehmed II’s forces capture the city, leading to a day of unprecedented massacre, pillaging and rape.


Key issues

The post-sack era

For sixty or so years after the sack of 1204, the history of the Byzantine Empire was one of a succession of Greek emperors based in Nicaea trying to unify the squabbling Greek statelets, negotiate with the new Latin rulers of Constantinople, while also managing relations with the Turks to the East and the Bulgars and Serbs to the North.

Family squabbles

Throw in repeated internecine rivalry within the extended families of the emperors themselves, and problems created by a series of religious divisions and you have an extremely complicated story to tell. The situation around the two sacks, in 1204 and 1453, are particularly complicated, but Norwich tells it all with admirable clarity, and finds the time to give a brief summary of the overall achievements of each of the emperors, men (and some women acting as regents) who were condemned to struggle with the steadily declining situation.

Schisms

The Arsenites took their name from the Patriarch Arsenius who excommunicated the emperor Michael VIII for his treatment of his young co-emperor and rival, John Lascaris (Michael had him blinded and confined to prison for the rest of his life). Michael had Arsenius deposed and replaced in 1267 but the Arsenites only grew in number and zeal, providing a powerful opposition for the rest of Michael’s reign.

The Hesychasts (from the Greek hesychasm meaning ‘holy silence’) teaching a meditation technique which could help the faithful attain a vision of ‘the divine, uncreated light which had surrounded Jesus Christ at his Transfiguration’. The practice spread sparking, as new movements do, reforming zeal among its adherents, and opposition to all the compromises and fudges of the orthodox establishment, until the church became divided into bitterly opposing factions of hesychasts and traditionalists, a schism which spilled over into politics and took up the energy of successive emperors throughout the 14th century.

The Catholic Church

By the 1200s the Roman Catholic Church demanded control over the Eastern Orthodox Church and was firmly of the view that the Easterners were schismatics, little better than heretics, a view dating from the actual schism of 1054, but accompanied by a background of suspicion and dislike.

In the last 250 years of its existence the empire was forced to approach the Papacy numerous times, begging for help against the encroaching Turks, in return for which the emperor pledged to convert his people en masse to Catholicism, at the 1274 Union of Lyon, and again in the 14th century. But this ploy never worked out because:

  1. all the senior Orthodox churchmen refused to co-operate
  2. the Greek people passively resisted all changes
  3. the papacy never came up with the material aid to the struggling empire which the emperor had bargained for

Crusades

We all know about the conventional and numbered sequence of crusades against Muslims in the Holy Land (and Egypt). Reading this book makes you aware of quite a few other ‘crusades’. I was surprised to learn of the many times Western princes and kings tried to get the pope’s approval for almost any armed venture by persuading him to call it a ‘crusade’.

  • 1190 the Holy Roman Emperor Frederick Barbarossa tried to secure papal blessing and the name of ‘crusade’ for his planned attack on Constantinople (p.161)
  • In 1265 Charles of Anjou and Provence, younger brother of King Louis of France, persuades pope Clement IV to declare Charles’s war against the pope’s arch-enemy, King Manfred of Sicily, a ‘crusade’ (p.225)
  • In 1280 the same Charles of Anjou (having defeated Manfred and become King of Sicily) persuades the pope also call his next campaign, a vast amphibious attack against Constantinople, a ‘crusade’ against the Eastern schismatics and heretics (p.249)
  • In 1396 Pope Boniface IX gives the name of ‘crusade’ (and historians call the Crusade of Nicopolis) to the vast army assembled by King Sigismund of Hungary. 10,000 French knights and 6,000 Germany knights joining Sigismund’s 60,000 who all set off down the Danube and, outside the city of Nicopolis, are massacred by the Turks. According to Norwich ten thousand captured prisoners were beheaded in the Sultan’s presence. (p.355)

Reading about the many, increasingly petty and secular, ‘crusades’ devalues them. Like the papal mechanism of ‘jubilees’ when all debts were meant to be forgiven, or the pope’s increasingly liberal use of ‘excommunication’, the term ‘crusade’ soon loses all religious meaning and becomes just another diplomatic tool in the endless series of conflicts which are the Middle Ages, just another tool in the armoury of popes struggling to maintain the independence of the Papal States and the authority of the Catholic Church.

The joke papacy

The devaluing of the idea of the ‘crusade’ was just part of the general absurdity of the papacy in the Middle Ages. The shenanigans surrounding the election of the popes, the interference of various kings (the King of France and the Holy Roman Emperor in particular) and the repeated setting up of popes and anti-popes by rival factions, who promptly excommunicated each other and all their followers, reduced the concept of God’s one representative on earth to a laughing stock.

As I count it, there were no fewer than 21 anti-popes in the period covered by this book (1080 to 1453), and it was also the period when the papacy left Rome altogether and based itself in Avignon (from 1309 to 1376) where it fell under the domination of the French King. It is utterly typical of the period that the French ‘exile’ was triggered after Pope Boniface VIII was arrested and beaten so badly by soldiers of King Philip IV of France that he died.

Venice

Venice was responsible for the sack of Constantinople and plays the role of bad guy for the remaining 250 years of the empire, repeatedly attacking and burning the city, often as part of its ongoing and intensely bitter feud against Italy’s other maritime state, Genoa. The sequence of events is long and very complicated but Norwich gives the sense that, right up to the very last moment, Venice was guided purely by commercial self-interest, determined to screw as much land and trading advantages out of the Byzantine Empire as possible even when the ’empire’ amounted to little more than a half-ruined city. Only in the last few months of its existence do the Venetians seem to have realised that the loss of Constantinople and the unimpeded ownership of the entire Balkan Peninsula by the Turks would put them on the Adriatic coast right opposite themselves. Too late they offered to send the emperor ships and troops, decades too late, maybe a century too late.

Mercenaries

After the Battle of Manzikert in 1071 the Seljuk Turks were effectively free to move into Anatolia. The process wasn’t immediate but within a decade they had taken control of the whole central portion of Anatolia, submitting the native Greek Christians to Muslim rule and laws. Most importantly Anatolia had been for a thousand years the source of a) food b) fighting manpower to the Eastern Empire. With its loss, the empire had to turn increasingly to paying for mercenary soldiers to fight its cause.

The loss of Anatolia had long since deprived Byzantium of its traditional source of manpower; for many years already it had had to rely on foreign mercenaries. (p.259, referring to the year 1300)

As the book progresses, you become aware that mercenaries fought on all sides. It was, for example, striking to learn that when, in 1211 the Seljuk Sultan of Iconium, Kaikosru, attacked the Byzantine forces of the emperor Theodore, both armies contained a contingent of Latin mercenaries at their core (p.190).

This sets the tone for the ever-increasing use of mercenaries by all sides: for example, the young general Michael Palaeologus – before he himself seized the throne – was sent into exile and ended up leading the Sultans Christian mercenaries in battle against the Mongol invaders in 1256 (p.205).

  • In 1258 Michael, now emperor, despatches an army against his Greek rival in the west, the Despot of Epirus: and this Byzantine army contains contingents from Hungary, Serbia, as well as Cuman and Turkish mercenaries (p.208)

‘Multicultural’ is not at all the right word, but the universal use of mercenaries brings home one of the many differences from our own ties. In our day we associate an army with the country which funds and organises it. We think of armies as being national. In those times an army could be made up of an extremely heterogenous group of man fighting for all kinds of reasons.

  • In 1302 a Byzantine force was caught just outside the city of Nicomedia by a Turkish army twice its size commanded by a local Ghazi named Othman. It wasn’t a decisive battle, the Byzantines turned and fled, the Turks proceeded west to the coast, ravaging all the towns and settlements they passed through. Historically the encounter is notable because it marks the first appearance of the legendary Othman, founder of the Ottoman Empire. But for the point I’m making the important thing is that the Byzantine force was largely composed of Alan tribesmen. (p.263)

As the reliance on mercenaries increased, successive emperors of Byzantium found themselves trapped  into paying the spiralling costs of even basic defence. More and more income was diverted to pay the insatiable demands of foreign fighters. Thus when around 1350 Symeon, Grand Duke of Muscovy, sent a large quantity of gold to pay for the restoration of the St Sophia church, the emperor of the time was forced to use the entire sum in order to pay mercenaries, Turkish mercenaries – Muslim mercenaries. The Grand Duke was not pleased.

Because if their pay wasn’t kept up, mercenaries were a dangerously double-edged weapon.

  • In 1263 Michael sends a fleet and army against the King of Achaia (one of the breakaway Greek kingdoms created after the 1204 sack of Constantinople), an army of some 15,000 men a third of who are Muslim Seljuk mercenaries. (p.220) This did not end well as half way through the campaign the mercenaries, who had not been paid for six months, suddenly demanded their wages and when these were not forthcoming, deserted to the other side (p.222)

This of course was the weakness of mercenaries: if you ran out of money, they stopped fighting for you and, as the years went by, the Empire became increasingly strapped for cash. The most notable example of this was the Grand Catalan Company.

The Grand Catalan Company

This was a powerful group of mercenaries led by Roger de Flor between the Sicilian Vespers in 1282 and Roger’s assassination in 1305. During this period they evolved to become one of the most efficient fighting forces in the Mediterranean and were hired by the Byzantine Emperor Andronicus II Palaeologus to fight the increasing power of the Turks.

Norwich gives a fascinating account of the colourful career of Roger himself (sent to sea aged eight, pirate captain by the age of 24) and of the brilliant campaign they undertook against the Turks. He explains that, if only the Catalan Company had followed up its initial victories against the Turks and pushed on into Anatolia it is conceivable that the Empire might have been able to seize much of the territory back, re-establish its agriculture and earlier model of military service and generally been restored. But the Catalans, as mercenaries, were only interested in loot and broke off the campaign to return to the sea and their treasure stores. 

It was fear about their increasing independence and refusal to obey orders which prompted the emperor to permit his other group of mercenaries – the Alans – to carry out a massacre of the Catalan Company during a feast at which Roger himself was murdered (the Alans had a long-festering grievance against the Catalans). The surviving Catalans went on a wild rampage through Adrianople (where the assassination took place) and beyond. It’s fascinating to learn that the memory of these massacres lasted so long that the monks of nearby Mount Athos prohibited the entrance of Catalan citizens until as recently as 2000.

Marriages

As explained in a previous blog post, in the absence of all international bodies or agreed norms of behaviour, one of the few ways rulers had of trying to control the chaos of endless international rivalries and war, was through family and kinship ties. Specifically, the tool of marrying off your brothers or sisters or sons or daughters to the children of other rulers you wished to secure an alliance with, or to structure the inheritance of property, specifically territories and kingdoms.

  • In May 1197 the Emperor Alexius III was obliged to stand impotently by while his niece, Irene, daughter of the blinded ex-emperor Isaac II, was married off by Henry VI King of Sicily to his own younger brother Philip of Swabia. (p.164)
  • When Henry of Hainault, Latin ruler of Byzantium, died in 1216, the Frankish barons elected his brother-in-law Peter of Courtenay to succeed him. In France at the time Peter set sail for the East with an army of 5,500 men, landing in Epirus and laying siege to the town of Durazzo. The town proved impregnable and Peter and most of his men were captured in the mountains of Albania and thrown in prison, never to be heard of again. His wife, Yolanda, had sailed direct to Constantinople where she adopted the title of Empress and regent for their new-born son. She consolidated her position by giving the daughter of her brother, Henry (who was named Mary) to the Emperor of the Byzantine government in exile in Nicaea, Theodore Lascaris.
  • When the Latin Emperor Robert I (the son Yolanda acted as regent for) died in 1228, leaving an eleven-year-old boy, Baldwin II, as his successor, the Latin barons offered the throne of Byzantium to an ageing adventurer and one-time King of Jerusalem, John of Brienne. John reluctantly accepted on the understanding that 11-year-old Baldwin would immediately marry his (John’s) own four-year-old daughter, Maria, and that she be given a sizeable dowry in the form of land. (p.195)
  • In 1235 John Asen emperor of Bulgaria signed a treaty of alliance with Nicaea which was sealed by the marriage of his daughter Helena to the son of the Nicaean Emperor John Vatatzes. (p.197)
  • In 1249 John Vatatzes secured a treaty of friendship with Michael II, Despot of Epirus (and illegitimate son of the despotate’s original founder, Michael I) by marrying his granddaughter Maria to Michael’s son Nicephorus. (p.200)

And so on and on.

In fact I noticed that there is a slowly increasing mention of treaties in the text, and it would be interesting to know how the concept of ‘the treaty’ changed and evolved over this long period and how it related to the early development of ‘the nation state’, whether there was an increasing recognition of the legal standing of treaties, or whether they remained agreements between individual leaders.

Whatever the theory, pieces of paper remained cheap and easy to tear up, whereas bonds of blood and marriage (and so grandparentage of the children of these unions) remained a primeval force understood by all sides.

  • In 1256 Tsar Michael Asen of the Bulgars was assassinated and succeeded by a boyar named Constantine Tich. Tich saw the strategic usefulness of an alliance with Byzantium and so he repudiated his wife in order to marry Irene, the daughter of Byzantine Emperor Theodore II. (p.205)
  • Early in 1258 Manfred of Sicily, the bastard son of Frederick II, invaded Epirus. The Despot of Epirus, Michael, was at that moment besieging the Byzantine city of Thessalonica so he decided to ally with Manfred against the Nicaean Empire, negotiated a deal with him and sealed it by giving Manfred the hand of his eldest daughter, Helena. (p.207)
  • In 1291 Charles II of Anjou proposed an alliance with Nicephorus, Despot of Epirus, against Constantinople, which he cemented by marrying his son, Philip, to Nicephorus’s daughter, Thamar. (p.260)

Child marriages

I was struck by the number of marriage contracts which involved very young children.

  • In 1136 Raymond of Poitiers, son of William IX, Duke of Aquitaine, married Constance, daughter of Bohemund II of Antioch, aged six, in order to give Raymond legitimacy as the new ruler of the Crusader Kingdom of Antioch. (p.77)
  • In September 1158 Theodora Comnena, niece of Byzantine emperor Manuel I Comnenus, was married to King Baldwin III of Jerusalem. She was 12, he was 28. (p.122)
  • On 2 March 1180 the Patriarch Theodosius celebrated the marriage of Princess Agnes of France to Alexius Comnenus of Constantinople. She was nine, her husband was ten. (p.137)
  • In 1244 the Nicaean Emperor John Vatatzes strengthened his position vis-a-vis the Latin kingdom by marrying Constance, the illegitimate daughter of the Holy Roman Emperor Frederick II. Constance was just 12-years-old and forced to take the Byzantine name Anna, and married to a man forty years older than her who was, as everyone knew, having an affair with one of her own waiting-women. (p.199)
  • In 1282 an ambitious new ruler came to the throne of Serbia, Stephen Miliutin, who within a year declared support for Charles of Anjou (the threatener from Sicily) and allied with the Despotate of Epirus (on the west Balan coast). The Byzantine Emperor Andronicus realised he had to neutralise this threat and when he heard that Miliutin’s legal wife had died (he was said to keep at least two concubines) he offered his own sister in marriage. Interestingly, the sister, Eudocia, flat out refused to be married and so Andronicus turned to the next best thing, his own daughter Simonis. Simonis was five years old and Miliutin 40. Amazingly, the little girl was taken by a Byzantine deputation to Thessalonica where the wedding was carried out by the Archbishop of Ochrid. Miliutin was thrilled that her dowry included most of the territory of Macedonia (which he coveted) and he agreed to allow little Simonis to remain in the Serbian nursery ‘for a few more years until she was old enough to live with him as his wife’. It is interesting to note that many people at the time saw this as immoral, and that the Patriarch of Constantinople, John XII, resigned in protest. (p.261)
  • In 1284, Andronicus II married Yolanda (who was renamed Eirene as Empress) who was eleven at the time. (p.275)

You could see this as the exploitation of the young, or as treating women as pawns – but I see it as treating people as pawns.

Everyone in any kind of position of power might well have had their own identity, character, wishes, plans and all the rest of the fol-de-rol surrounding ‘personality’ and ‘individuality’ which we in our post-Enlightenment, post-religious, consumer society take for granted. But eminent people living then existed primarily as pieces on a vast chess board, to be switched, taken, or sacrificed without a moment’s hesitation, as the game demanded.

  • Manfred of Sicily was defeated by the merciless Charles of Anjou at the Battle of Benevento on 26 February 1266. Only after three days was Manfred’s body found and Charles then denied it a Christian burial but had it placed by the bridge at Benevento so that every passing soldier in his army could throw a stone at it and build up a burial cairn. Manfred’s wife, Helena of Epirus, and is three young children were imprisoned at Nocera. Of the four, three never appeared again: one son was still there in the same prison 43 years later. (p.225)
  • In December 1355 the Emperor John V sent a desperate letter to Pope Innocent VI begging for help. If the pope would send him 500 knights, a thousand infantry, fifteen transport ships and five galleys, John promised to oversee the conversion of the Greek Orthodox church to Roman Catholic rites and personnel. In addition he would send his five-year-old son, Manuel, to be raised a Catholic and disposed of as the pope saw fit. (p.326)

Youth

Very young some of these children may well have been but then, almost everyone was young. Lots of the rulers died in their 30s or 40s. Norwich repeatedly comments that rulers in their 60s were old for their time. And there are some staggering examples of how much was expected, and achieved, by people of incredible youth.

  • In 1268 Manfred of Sicily’s nephew Conradin marched south from Germany in a bid to save his family’s inheritance from the aggressor Charles of Anjou. On 23 August Charles shattered his army at Taglioacozzo. Conradin captured, subjected to a kangaroo court and then beheaded in the market square in Naples. He was just sixteen and the last of the Hohenstaufen dynasty. (p.225)

The most striking example of youth achieving astonishing things is the final capture of Constantinople itself by the Ottoman Sultan Mehmed II the Conqueror. Norwich shows in detail how Mehmed led Turkish forces to defeat the crusade led by John Hunyadi after the Hungarian incursions into his country broke the conditions of the truce Peace of Szeged, and then goes on to explain the thinking behind his final assault on Constantinople, and describe in great details both the preparations for the siege – by land and by sea – and a day-by-day account of the siege, breach and fall of the city. The attacking Turks gave themselves up to an orgy of violence and destruction, massacring and raping civilians, desecrating, looting and torching the churches. Through the mayhem strode the Sultan, surrounded by his bodyguard, to the vast church of Hagia Sophia, which he had already decided would be converted into the largest mosque in the world. He knelt and kissed the floor and thanked Allah for his victory.

And he had achieved all this – by the age of twenty-one!

The generality of the heartless, calculating treatment meted out to everyone was symbolised for me by the widespread blinding of the powerful when they were brought low or presented a threat – not as a punishment, but to neutralise them as a threat.

Blindings

From the eight or nine hundreds onwards it became customary to blind rival emperors you had overthrown and/or their male children, in order to permanently prevent them becoming a threat. It was considered less cruel than simply murdering them.

  • In 1077 the general Nicephorus Bryennius made a bid for the throne, but was captured and blinded by Nicephorus III Botaneiates. (p.64)
  • 1204 following the fall, sack, and occupation of Constantinople, the Emperor Alexius V ‘Mourtzouphlos’ was blinded
  • In 1218 Boril of the Bulgars was overthrown by his cousin John II Asen and blinded. (p. 193)
  • 1230 John Asil of Bulgaria defeated Theodor of Thessalonica and had him blinded. (p.197)
  • In 1295 the Empire’s foremost general, Alexius Philanthropenus, rose up in revolt. He was quickly defeated, captured and blinded. (p.262)
  • In 1373 the Ottoman Sultan Murad’s son, Sauji, rose against him. The Sultan quickly defeated the rebel forces and had his son blinded. (p.336)

But the most disgusting of the many, many blindings in this book is of a helpless eleven-year-old boy.

  • John IV Lascaris was only seven years old when he inherited the throne on the death of his father, Theodore II Ducas Lascaris. He was put under the regency of the bureaucrat George Muzalon who was hugely unpopular and swiftly murdered by the nobility (in church). The leader who emerged was the successful young general Michael Palaeologus who usurped the regency and then, on January 1, 1259, made himself co-emperor as Michael VIII. (Michael was, in fact, John’s second cousin once removed.) After Michael’s conquest of Constantinople from the Latin Empire on July 25, 1261, Michael needed to secure full control of the Byzantine inheritance and so four months later he had John IV – who he’d left behind in the palace at Nicaea – blinded on Christmas Day. It was the boy’s eleventh birthday. He was then sent to a prison in Bithynia where he lived for another fifty years. Many at the time were disgusted by this act and it led to Michael’s excommunication by the Patriarch Arsenius Autoreianus. (p.212)

Political mutilation in Byzantine culture

All this can be set against what became an embedded habit of the Ottoman Dynasty which was that, upon the death of each Sultan, his sons fought for power and the victor had all his defeated rivals strangled. This wasn’t just a bad habit practised by the occasional wicked sultan – it was enshrined in Ottoman law.

Sultan Mehmed the Conqueror’s Law of Governance imparted the right of executing the male members of the dynasty to his son in order to prevent an interregnum.

To prevent attempts at seizing the throne, reigning sultans practiced fratricide upon accession, starting with Murat I in 1362. Both Murad III and his son Mehmed III had their half-brothers murdered. The killing of all the new sultan’s brothers and half-brothers (which were usually quite numerous) was traditionally done by manual strangling with a silk cord. As the centuries passed, the ritual killing was gradually replaced by lifetime solitary confinement in the ‘Golden Cage’ or kafes, a room in the harem from where the sultan’s brothers could never escape, unless they happened to become heir presumptive. Some had already become mentally unstable by the time they were asked to reign. (Wikipedia)

Slavery

I also cannot get over the way slavery is so casually mentioned. Again and again entire populations of towns, cities and regions are led off into slavery. We are told slavery was ubiquitous throughout the Muslim lands, but also appears to have been common in the Byzantine Empire, and was practiced by all the lesser peoples fringing the narrative, like the Bulgars and Hungarians and Serbs. I am puzzled why the ubiquity of slavery across Europe and the Middle East for most of the Middle Ages isn’t better known, isn’t made more of – especially when you consider the enormous fuss which is made about the African slave trade carried out by the West European nations from the 1500s onwards.

  • After the Turks seized Gallipoli they began conquering Thrace, taking Didymotichum in 1361, Adrianople in 1362. ‘In every city and village that was captured, a large part of the population was transported to slavery in Asia Minor’ (p.328)
  • When the Turks seized the city of Thessalonica in 1430, they looted all the churches and burnt many of them to the ground, massacring most of the male population and selling some seven thousand women and children into slavery. (p.395)
  • In preparation for the final siege the Turks took the nearby island of Prinkipo. the garrison was burnt alive in their fortress, the entire civilian population was sold into slavery. (p.424)
  • The monk and scholar George Scholarius was sold into slavery along with all his fellow monks (p.442)

Why is black African slavery discussed, raised, debated and lamented on an almost daily basis in books, films, art galleries and the media – while the European and Asian slave trade is completely and utterly absent from all forms of culture whatsoever, except tucked away as a minor detail of histories of the classical world and Middle Ages?

Weren’t the huge numbers of people sold into slavery in the 1100s, 1200s, 1300s and 1400s just as much human beings with lives and hopes and fears, as the people sold into slavery in the 1600s, 1700s and 1800s?

So why commemorate the one and not the other?


Byzantine emperors (1204 – 1453)

Theodore I Lascaris (1205 – 1222)

Son-in-law of Alexius III, Theodore was elected emperor by the citizens of Constantinople on the day before the city fell to the Crusaders. He fled to Nicaea, where he organized the Greek resistance to the Latins. Crowned emperor in 1208. He managed to stop the Latin advance in Asia and to repel Seljuk attacks, establishing the Empire of Nicaea as the strongest of the Greek successor states.

John III Ducas Vatatzes (15 December 1221 – November 1254)

Born around 1192, John became the son-in-law and successor of Theodore I in 1212. A capable ruler and soldier, he expanded his state in Bithynia, Thrace and Macedonia at the expense of the Latin Empire, Bulgaria and the rival Greek state of Epirus.

John Vatatzes had been a great ruler… one of the greatest, perhaps, in the whole of this history. (p.203)

Theodore II Lascaris (1254 – 1258)

Born in 1222 the only son of John III, he succeeded on his father’s death. His reign was marked by his hostility towards the major houses of the aristocracy, and by his victory against Bulgaria and the subsequent expansion into Albania.

John IV Lascaris (1258 – 1261)

Born on 25 December 1250 as the only son of Theodore II, John succeeded on his father’s death. Due to his minority, the regency was exercised at first by George Mouzalon until his assassination, and then by the young successful general Michael Palaiologos who, within months, was crowned senior emperor.

After the recovery of Constantinople in August 1261, Palaiologos sidelined John IV completely, and had the 11-year-old boy imprisoned and blinded. John IV died c. 1305.

Michael VIII Palaeologus (1259 – 1282)

One of the hero emperors, this confident young general campaigned against the Latins and Greek rivals and it was forces under his command who discovered Constantinople was virtually unguarded, the Latin garrison being away on a campaign against some island, and so sneaked in and took the city by surprise. Michael had to be woken up at his camp two hundred miles away to be told it had happened. He quickly marched on the capital and was greeted with acclaim by the long-suffering Greek population.

Andronicus II Palaeologus (1282 – 1328)

Son of Michael VIII, he was born on 25 March 1259, named co-emperor in 1261, crowned in 1272, and succeeded as sole emperor on Michael’s death.

Favouring monks and intellectuals, Andronicus neglected the army and his reign saw the collapse of the Byzantine position in Asia Minor. He named his son Michael IX co-emperor. In a protracted civil war, he was first forced to recognize his grandson Andronicus III as co-emperor and was then deposed outright.

Andronicus III Palaeologus (1328 – 1341)

Son of Michael IX, Andronnicus deposed his grandfather Andronicus II in 1328 and ruled as sole emperor until his death. He was ably supported by John Cantacuzenos, his reign saw defeats against the Ottoman emirate but successes in Europe, where Epirus and Thessaly were recovered.

John V Palaeologus (1341 – 1376) part one

Only son of Andronicus III who neglected to crown him co-emperor or formally declare him his heir, so that at his father’s death a destructive civil war broke out between his regents and his father’s closest aide, John VI Cantacuzenos, who ended up seizing power and being crowned co-emperor.

The conflict ended in 1347 with Cantacuzenos recognized as senior emperor, but he was deposed by John V in 1354 during another civil war. Matthew Cantacuzenos, raised by John VI to co-emperor, was also deposed in 1357. John V appealed to the West for aid against the Ottomans, but in 1371 he was forced to recognize Ottoman suzerainty. He was deposed in 1376 by his son Andronicus IV.

John VI Cantakcuzenos (1347 – 1354)

A maternal relative of the Palaeologoi, he was declared co-emperor on 26 October 1341, and was recognized as senior emperor for ten years after the end of the civil war on 8 February 1347. Deposed by John V in 1354, he became a monk, dying on 15 June 1383.

Andronicus IV Palaeologus (1376 – 1379)

Son of John V and grandson of John VI, he was born on 2 April 1348 and raised to co-emperor c. 1352. He deposed his father on 12 August 1376 and ruled until overthrown in turn in 1379. He was again recognized as co-emperor in 1381 and given Selymbria as an appanage, dying there on 28 June 1385.

John V Palaeologus (1379 – 1390) part two

Restored as senior emperor, John was reconciled with Andronicus IV in 1381, re-appointing him co-emperor. He was overthrown again in 1390 by his grandson, John VII.

John VII Palaeologus (April 1390 – September 1390)

Son of Andronicus IV, John was born in 1370, and named co-emperor under his father in 1377–79. He usurped the throne from his grandfather John V for five months in 1390, but with Ottoman mediation he was reconciled with John V and his uncle, Manuel II. He held Constantinople against the Ottomans in 1399–1402, and was then given Thessalonica as an appanage, which he governed until his death on 22 September 1408.

John V Palaeologus (September 1390 – February 1391) part three

Restored to senior emperor, he ruled until his death in February 1391. If you count the time from his first ascension to the throne John V reigned longer than any other Byzantine emperor.

At one of the most desperate moments of its history, the Empire was governed by a ruler who was neither intelligent nor far-sighted, and who possessed virtually none of the qualities necessary to a successful statesman. (p.347)

Manuel II Palaeologus (1391 – 1425)

Second son of John V, he was born on 27 June 1350. Raised to co-emperor in 1373, Manuel became senior emperor on John V’s death and ruled until his death. He travelled to the West European courts seeking aid against the Turks, and was able to use the Ottoman defeat in the Battle of Ankara to regain some territories and throw off his vassalage to them.

John VIII Palaeologus (1425 – 1448)

The Empire of which, on 21 July 1425, the thirty-two-year-old John Palaeologus became sole basileus was effectively bounded by the walls of Constantinople; and Constantinople now presented a dismal picture indeed. (Norwich p.388)

Eldest surviving son of Manuel II, John was born on 18 December 1392. Raised to co-emperor about 1416, he succeeded his father on his death. Seeking aid against the resurgent Ottomans, he ratified the Union of the Churches in 1439 i.e. in a desperate bid to secure help from the Pope and the Western powers, he promised to subjugate the Eastern Orthodox Church to Rome.

Constantine XI Dragases Palaeologus (1449 – 1453)

The fourth son of Manuel II and Serbian princess Helena Dragaš, he was born on 8 February 1405.

As Despot of the Morea since 1428, Constantine distinguished himself in campaigns that annexed the Principality of Achaea and brought the Duchy of Athens under temporary Byzantine suzerainty, but was unable to repel Turkish attacks under Turahan Bey.

As the eldest surviving brother, he succeeded John VIII after the latter’s death. Confronted by the aggression of the new Ottoman sultan, Mehmet II, Constantine acknowledged the Union of the Churches and made repeated appeals for help to the West but in vain. Refusing to surrender the city, he was killed during the final Ottoman attack on 29 May 1453.

The Sack of Constantinople in 1204

There was never a greater crime against humanity than the Fourth Crusade.
(Sir Steven Runciman, 1954)

Until I read John Julius Norwich’s account of the Fourth Crusade, which ended with the devastating sack of Constantinople in 1204, I hadn’t appreciate what a seismic and unmitigated disaster it was.

Norwich’s account of the Latins’ destruction of the biggest, richest city in the world was so harrowing I was depressed for days and found it difficult to continue reading the book in which he describes it, Byzantium: The Decline and Fall.

Like reading detailed accounts of Hiroshima, I just felt that…. after seeing humanity revealed in such appalling colours, why… why go on with anything?

For me, personally, the reason to go on is to understand better. Not to understand perfectly, which I am confident, or acknowledge, is beyond human wit. But just because perfect understanding is an impossible platonic absolute, doesn’t mean that some understanding isn’t better than none. And, for me, personally, understanding things brings sweet mental joy.

And so, just like Norwich’s detailed description of the Sack of Rome by Alaric and the Visigoths in 410, a detailed description of the Fourth Crusade and the Sack of Constantinople makes it so much more comprehensible. Only if you follow the events in the most detailed way possible do you realise that a distant event which is often treated as a single thing – the Sack of Constantinople – was in fact a complex concatenation of accidents and misunderstandings and misjudgments and bad agreements. It took the malevolence of some people (the doge of Venice), the chancer’s gamble of the pretender to the Byzantine throne Alexius III, and then the passive acquiescence of the majority of the crusaders, to take place. Reading the details makes you realise that a) this is how ‘history’ i.e. human events, work, in complex unexpected ways, where all kinds of spokes are stuck into the machine and b) makes you realise how the nature of human life, human experience, human societies, and big political events, doesn’t change much. I’m thinking of the sequence of events which brought about Brexit, and which we are still in the middle of. The results aren’t as murderous and destructive as the sack of Constantinople – but they are recognisably the product of the same confused, chaotic species.

In other words, reading about the sack itself is grim and depressing, but the knowledge and insight it gives you into human nature and how human affairs operate, are powerful and liberating.

Summary

This is the short version you’re likely to read in books focusing on other subjects, such as the crusades as a whole, or the Middle Ages.

In April 1204 the Latin, Western soldiers of the Fourth Crusade laid siege to Constantinople, capital of the Byzantine Empire. On 12 April the crusader armies breached the city’s defences and stormed the city. Attacking Venetian forces tried to use fire as a defensive shield but it quickly got out of control and burned unchecked through the city. As if that wasn’t catastrophic enough, once the crusaders had established a bridgehead, they proceeded to spend three days pillaging and looting the city.

The Greek emperor fled and leaders of the ruling families were driven into exile, so the crusaders chose a Latin ruler – Baldwin of Flanders – who was crowned Emperor Baldwin I and inherited about a quarter of the territory his Greek predecessors had ruled This Latin rule of the Byzantine Empire was to last just under 60 years, before a Greek ruler and army re-established Greek power.

After the city’s sacking, most of the Byzantine Empire’s territories were divided up among the Crusaders, but Byzantine aristocrats also established a number of small independent splinter states, one of them being the Empire of Nicaea, which would become the kernel of Greek resistance and – after a long series of small wars, setbacks and struggles to reunify Greek leadership – would eventually recapture Constantinople in 1261 and restore the Greek tradition and religion to the city of Constantine.

But the restored Byzantine Empire never managed to reclaim all its former territorial or economic strength, and eventually fell to the rising Ottoman Sultanate in 1453.


Background

The Latin West and Greek East of Christendom had been growing apart for centuries, with the pope in Rome arrogating more and more power and authority to himself, insisting the Eastern church submit to his authority, and Western clerics as a whole coming to regard the Eastern Orthodox church as schismatic and in error on a wide range of theological and procedural issues. Norwich’s three volumes of Byzantine history are littered with theological, administrative and geopolitical arguments between the papacy and the emperor or Patriarch (head of the Eastern Church) of Constantinople. This helps explain the indoctrination of western crusaders that the Byzantines were exotic, untrustworthy, almost heretics.

But the real focus of the story is the growing rivalry between the maritime republic of Venice, whose wealth was based on shipping and trading across the Muslim Middle East to the ‘Indies’ where spices and pepper came from, and Byzantium as the established power in the region. Successive emperors of Byzantium had been obliged to make trade treaties with Venice and given Venetian merchants extensive privileges in the city, such as an entire quarter down by the docks for their use and trading rights across the Empire’s territories and islands.

The sack had three causes:

  1. long-term mistrust between Latin Westerners and Greek Byzantines
  2. the long-term rivalry with Venice which wished to supersede Byzantium as the main power in the eastern Mediterranean
  3. a short-term, proximate cause which was a string of accidents to do with the mismanagement of the Fourth Crusade, which were ruthlessly exploited by the doge of Venice, Enrico Dandolo, to fulfil point 2.

East-West relations

1. Mass arrest of the Venetians 1171

Latin Catholics from the rival cities Venice and Genoa dominated the city’s maritime trade and financial sector, having secured concessions from successive Byzantine emperors, which resulted in a virtual maritime monopoly and stranglehold over the Empire by the Venetians.

Rich Italian merchants grew very rich and so did the Byzantine aristocrats who allied with them, leading to popular resentment among the middle and lower classes in both the countryside and in the cities.

The Venetians resented that their main Italian rivals, the Genoese, also had extensive quarters in Constantinople, and in 1171 the Venetians attacked and largely destroyed the Genoese quarter. The Emperor retaliated by ordering the mass arrest of all Venetians throughout the Empire and the confiscation of their property (a move he had probably been meditating for some time – the Genoese attack gave him a pretext). As with all civil unrest, there were also rapes and the burning of houses. Infuriated, the Venetians launched a naval expedition to attack Byzantine interests, which failed, but the encouraged the Empire’s enemies, specifically the Serbs – to take advantage of the unrest and launch land attacks.

Relations were only gradually normalized, reaching an uneasy peace in the mid-1180s.

2. The massacre of the Latins

But the simmering resentment didn’t go away and burst out anew in the Massacre of the Latins which took place in Constantinople in April 1182.

After the death of Emperor Manuel I in 1180, his widow, the Latin princess Maria of Antioch, acted as regent to their son and became notorious for the favoritism she showed to Latin merchants and the big aristocratic land-owners.

In April 1182 she was overthrown by the ageing general Andronicus I Comnenus. He marched on Constantinople and entered the city in a wave of popular support. But the celebrations quickly got out of hand and escalated into mob violence against the hated Latins. The ensuing massacre was indiscriminate: Latin men, women and children were attacked in the street, their houses burnt down, Latin patients lying in hospital beds were murdered. Houses, churches, and charities were looted. Latin clergymen received special attention and Cardinal John, the papal legate, was beheaded and his head dragged through the streets at the tail of a dog.

Andronicus finally took control and curtailed the rioting, but the massacre obviously left profound bad feeling. The Normans under William II of Sicily in 1185 sacked Thessalonica, the Empire’s second largest city, while over the next decade or so, the German emperors Frederick Barbarossa and Henry VI both tried to get papal approval to mount an attack on Constantinople.

The Fourth Crusade

Henry VI’s failed expedition

This fraught relation between East and West, and especially between Byzantium and Venice, was the difficult background to the Fourth Crusade and largely explains what happened next.

The Third Crusade had ended in 1192 with a treaty signed between Richard I of England and Saladin, leader of the Saracen forces, agreeing that Jerusalem would remain under Muslim rule but that Christian pilgrims and traders would be assured safe passage to visit the city.

Almost immediately the failure to liberate Jerusalem led to calls for a new crusade to finish the job. In 1195 there was one of those large-scale western incursions into the area which aren’t included in the canonical ‘crusades’ but which Norwich describes in just as much detail – the steady rumble of expeditions, wars, raids, alliances and defeats which fill Norwich’s pages and help put the crusades into a broader context of unending conflict.

Henry VI, the second son of the Holy Roman Emperor Frederick Barbarossa, organised a new Eastern expedition and in the summer of 1197 a large number of German knights and nobles, headed by two archbishops, nine bishops, and five dukes, sailed for Palestine. There they captured Sidon and Beirut, but then the army heard that Henry himself had died at Messina in Sicily on his way to the Holy Land and many of the nobles and clerics returned to Europe. Deserted by much of their leadership, the rank and file crusaders panicked before the advance of a Muslim army from Egypt, and fled to their ships in Tyre. Thus ended this brief Western foray.

Pope Innocent III preaches the fourth crusade

Pope Innocent III succeeded to the papacy in January 1198 and immediately began preaching a new crusade. The kings of Germany, France and England were all distracted by dynastic squabbles, but the pope managed to get a leader in the shape of Count Thibaut of Champagne who, in 1199, committed to the crusade and began rallying knights. In the event, Thibault himself he died in 1201 and was replaced by an Italian count, Boniface of Montferrat.

Richard the Lionheart’s advice – attack Egypt

Now, on his return from the third crusade in 1192, King Richard of England had given his opinion that the main goal of any future crusade should be to seize Egypt. Jerusalem is far to the south of the east Mediterranean coastline and experience had shown that, going the land route through Anatolia (modern Turkey) tended to focus the military efforts of the crusaders on the territory they passed through – on Cilicia and Syria and Antioch and so on, in the north of Palestine – whereas Jerusalem is far to the south, much closer to the heart of what had been the Fatimid Dynasty in Egypt.

The idea being that whoever held Egypt would find it easy to secure Jerusalem as a strategic add-on and would have a strong secure hinterland. The leaders of the fourth crusade took all this on board and planned from the beginning to launch a naval campaign against Muslim Egypt.

The deal with Venice

However, an invasion of Egypt would require ships and the only Christian kingdom with the maritime capacity to help was Venice. Thus Boniface and the other leaders sent envoys to Venice, Genoa, and other city-states in 1200 to negotiate a contract for transport to Egypt.

Venice agreed to help. Specifically, Venice agreed to build the ships necessary to transport 33,500 crusaders across the Med. The agreement made for a full year of preparation on the part of the Venetians to build numerous ships and train the sailors who would man them. All this would take place at the cost of her own commercial activities. Venice also negotiated for permanent possession of ports seized in the Holy Land. The crusade was to be ready to sail on 24 June 1203 and make directly for the Ayyubid capital, Cairo. The agreement was ratified by Pope Innocent, with a solemn ban on attacks on Christian states.

However, nobody had enforced commitment to the Venice plan on the heterogenous armies and forces scattered all across Europe, and so various contingents sailed under their own steam from a variety of European ports. The number of crusaders who actually turned up at Venice in the appointed month of May 1202 was about a third of the expected 33,500.

Reasonably enough, the Venetians, under their aged and blind Doge Enrico Dandolo, would not let the crusaders leave without paying the full amount agreed to, some 85,000 silver marks. The crusaders could only manage 35,000 silver marks between them. This was disastrous for the Venetians, who had suspended their usual trading for a year, trained sailors and so on, in order to fulfil the deal.

Doge Dandolo proposes an attack on Zara

It is now that the Doge Dandolo starts to emerge as the wicked genie of the expedition. Dandolo proposed that to pay off their debts the crusaders should help Venice with a spot of bother: the port of Zara in Dalmatia had traditionally been dominated by Venice but had rebelled in 1181 and allied itself with King Emeric of Hungary. Dandolo told the crusaders they could pay off their debt if they helped Venice seize back control of Zara.

Now King Emeric was himself a Catholic and had taken the cross in 1195, so many of the crusaders understandably refused to countenance attacking Zara, and some, including a force led by the elder Simon de Montfort, returned home. Also, as soon as he learned about the proposal, the Pope wrote a letter to the crusading leadership threatening excommunication if they attacked another Christian state. However, this letter was kept secret from the ranks of the crusader army, which proceeded to take ship across the Adriatic and besiege Zara in November 1202.

Although the inhabitants of Zara hung banners from their buildings with crosses on to point out that they were fellow Christians, the crusaders quickly breached the walls and proceeded to ransack and pillage the city. Giving way to crude greed, the Venetians and other crusaders came to blows over the division of the spoils.

When Innocent III heard of the sack of Zara, he sent a letter to the crusaders excommunicating them and ordering them to return to their holy vows and head for Jerusalem. The leaders kept this letter from the troops, and replied to the pope that they had been forced to do it by the Venetians, having had no alternative between carrying out the attack or calling off the whole crusade.

The pope relented and in February 1203 rescinded the excommunications against all non-Venetians in the expedition. Somewhere someone must have done a study of just how ineffectual papal excommunications were in the Middle Ages.

The fatal deal with Alexius IV Angelus

Meanwhile, the nominal leader of the crusade, Boniface of Montferrat, had left the fleet before it sailed for Zara, to visit his cousin Philip of Swabia. At Philip’s court he found the exiled Byzantine prince Alexius IV Angelus, Philip’s brother-in-law and the son of the recently deposed Byzantine emperor Isaac II Angelus. (Isaac II had been deposed and blinded by his older brother, Alexius Angelus, who then claimed the throne as Alexius III. Alexius IV wasn’t Alexius IV yet, but would be if he could only reclaim the throne.)

Now Alexius proceeded to make the two would-be crusaders an offer: if they could get the crusaders to sail to Constantinople, and overthrow the reigning emperor Alexius III Angelus, and restore his father and himself to the Byzantine throne, then Alexius would:

  1. use the wealth of the Byzantine Empire to pay the entire debt owed to the Venetians
  2. give 200,000 silver marks to the crusaders
  3. give 10,000 Byzantine professional troops for the Crusade
  4. pay for the permanent maintenance of 500 knights in the Holy Land
  5. offer the service of the Byzantine navy to transport the Crusader Army to Egypt
  6. place the Eastern Orthodox Church under the authority of the Pope

This fantastic offer was passed on to the leaders of the Crusade as they wintered at Zara and they enthusiastically agreed, seconded by Doge Dandolo – although the latter knew that Alexius could never keep these promises: he knew that Byzantium didn’t have that much money and would never agree to submit its church to Rome. Dandolo did, though, see at a glance the benefits for Venice in such an arrangement, which were:

  • revenge for the massacre of the Latins and other historical grievances
  • seizure of Constantinople’s significant wealth
  • by reinstating a large Venetian colony in the city, gaining a permanent commercial advantage over Venice’s rival, Genoa

Even now there were dissenters among the crusade’s leaders who (correctly) thought it was no part of a crusade against the Muslims to attack the mainstay of Christian power in the East. Led by Reynold of Montmirail, they sailed directly on to Syria.

Diversion of the crusade to Constantinople

But the majority of the fourth crusade now set sail for Constantinople in April 1203. The fleet consisted of some 60 war galleys, 100 horse transports and 50 large transports (manned by 10,000 Venetian oarsmen and marines). The Pope hedged and issued an order against any more attacks on Christians unless they were actively hindering the Crusader cause, but he did not condemn the scheme outright.

The crusaders attack Constantinople

When the Fourth Crusade arrived at Constantinople on 23 June 1203, the city had a population of approximately 500,000 people, a garrison of 15,000 men (including 5,000 Varangians), and a fleet of 20 galleys. Norwich emphasises that the city’s defences had been left to decay by the useless emperor Alexius III Angelus, and most of the galleys had fallen into disrepair.

The crusaders delivered their ultimatum demanding that that the emperor Alexius III should abdicate to make way for his nephew, Alexius IV. The emperor refused. The crusaders attacked the suburbs of Chalcedon and Chrysopolis. When about 200 ships, horse transports, and galleys delivered the crusading army across the narrow strait of the Bosphorus from Asia to Europe, Alexius III had lined up the Byzantine army in battle formation along the shore but, when the crusader actually knights charged, the Byzantine army turned and fled.

The Crusaders followed south along the shore and attacked the Tower of Galata. From this tower stretched a massive chain across the Golden Horn, the strait of water up the east side of the city, preventing entry to enemy ships. The crusaders took the tower and lowered the chain, allowing the Venetian fleet to sail up the Golden Horn. This is a narrow strip of water and the crusader galleys were able to come up close against the city’s seaward walls. Here they presented the pretender to the throne, Alexius IV, but were surprised when the people and soldiers of Constantinople jeered from the battlements. The crusaders had been told the people were in the grip of a cruel dictator and that they and Alexius would be greeted as liberators. Now they began to realise this was not true.

The crusaders set about attacking the city, combining an attack on the land walls at the north-west, with attacks on the sea walls from the fleet in the Horn. Eventually a breach was made and the crusaders entered the city. They were forced back by the Byzantine response and set a fire to keep off their attackers. This fire got out of control and was the first of the disastrous fires which were to burn through a large part of the city, this first one leaving an estimated 20,000 people homeless.

Alexius III made one last foray out to face the crusaders, but compounded his reputation for cowardice and ineffectiveness by turning his 8,500 men back in the face of the crusaders’ smaller force of 3,500. The impact of the fire and of this dismal capitulation led to a collapse in morale among the defenders. Alexius fled the city with his favourite daughter and courtiers.

The Byzantine officials now quickly declared the runaway emperor deposed and restored blind old Isaac II to the throne.

This presented the crusaders with a dilemma. The main, official, justification for the whole expedition was supposed to be restoring Isaac and his son, Alexius IV, who had proposed the whole scheme in the first place, to the throne. Now the Byzantines had called their bluff and restored Isaac. The crusaders responded that they would only recognize the authority of Isaac II if his son was raised to co-emperor, but the Byzantines again called the crusaders’ bluff by immediately agreeing to this, taking Alexius into the city and hurriedly arranging for his coronation at Hagia Sophia where he was crowned Alexius Angelus IV, co-emperor.

Alexius is unable to pay

As Norwich makes all too plain, Alexius now realised what a dreadful error he had made. The mismanagement of the Angelus dynasty over the previous decades had left Byzantium’s coffers bare, and Alexius III had made it worse by fleeing with as much imperial treasure as he could carry.

Alexius IV now ordered the seizure and melting down of priceless icons and church plate to use their gold and silver to pay off the impatient crusaders who were waiting across the Golden Horn in the suburb of Galata. Forcing the populace to destroy their most precious icons to satisfy an army of foreign schismatics did not endear Alexius IV to the citizens of Constantinople. Alexius negotiated a six-month extension to his pledge to the crusaders, making it now fall due in April 1204. Alexius IV then led 6,000 men from the crusader army against his rival Alexius III in Adrianople, with a view to seizing back the treasure his uncle had stolen and whatever could be ransacked from the Empire’s second city.

The Great Fire of Constantinople

But during the co-emperor’s absence in August 1203, rioting broke out in the city against the arrogant Latin occupiers, a number of whom were killed. In retaliation armed Venetians and other crusaders entered the city from the Golden Horn and, among other mayhem, discovered a church which had been converted into a mosque to cater to Constantinople’s not insignificant Muslim population. Citizens, both Greek and Muslim, rallied to the defence of this building and, to cover their retreat, the Latins started a fire, which – as is the way with fires – quickly spread out of control.

This became the ‘Great Fire’ of Constantinople which burnt from 19 to 21 August, destroying a large part of the city, consuming many ancient palaces and churches, and leaving an estimated 100,000 homeless. Amid the ruins the demoralised citizenry struggled on, while the crusaders waiting impatiently for their money.

The overthrow of Alexius IV

In January 1204, blind old Isaac II died, probably of natural causes, and rule now passed to his lamentable son, Alexius IV. The Byzantine Senate elected a young noble Nicolas Canabus to be co-emperor, in what was to be one of the last known acts of this ancient institution. However he declined the appointment and sought church sanctuary. Who can blame him?

Now during this period of crisis a nobleman called Alexius Ducas (nicknamed Mourtzouphlos, referring to his bush eyebrows) had led Byzantine forces during the initial clashes with the crusaders, winning respect from both the army and the people. And so it was Mourtzouphlos who one night entered the bed chamber of Alexius IV, told him there was rioting outside and the people were baying for his blood, led him through secret passages in the palace, to a dungeon where he chained and locked him up. Then returned to join his supporters and have himself proclaimed Emperor Alexius V. A few weeks later Alexius IV, the man who had caused all this trouble with his foolish promise to the crusaders, was strangled.

Alexius immediately took control of the Byzantine resistance and had the city fortifications strengthened, as well as recalling loyal troops from the provinces to bolster the Constantinople garrison.

The crusaders and Venetians, incensed at the murder of their supposed patron, demanded that Mourtzouphlos honour the contract that Alexius IV had made. The terms, if you remember, were to:

  1. use the wealth of the Empire to pay the entire debt owed to the Venetians
  2. give 200,000 silver marks to the crusaders
  3. give 10,000 Byzantine professional troops for the Crusade
  4. pay for the maintenance of 500 knights in the Holy Land
  5. offer the service of the Byzantine navy to transport the Crusader Army to Egypt
  6. place the Eastern Orthodox Church under the authority of the Pope

The crusaders renew their attack

Alexius V refused for the simple reason that there was nowhere near that much money in the imperial treasury. In March he ordered the forcible expulsion of all Latins from the city, which , and so in April the crusaders launched another attack on the city. Alexius V’s army put up a strong resistance, hurling projectiles onto the crusader’s siege engines, shattering many of them, and bad weather also hampered the attackers.

Pope Innocent III again sent a message ordering the crusaders not to attack, but once again the papal letter was suppressed by the clergy and never made public. While the Latin crusaders prepared to attack the land walls the Venetian fleet drew close to the sea-walls in an attempt to storm them.

On 12 April 1204, the weather conditions finally favoured the crusaders. A strong northern wind helped the Venetian ships get close to the seaward walls while on the land approach, the crusaders managed to make a hole in the walls through which a force of crusaders was able to crawl and overpower the defenders.

The crusaders captured the Blachernae section of the city in the northwest and used it as a base to attack the rest of the city. Alexius V fled the city accompanied by his wife and mother-in-law. In the Hagia Sophia Constantine Lascaris was acclaimed emperor but, when he failed to persuade the Varangian guard to continue the fight against the crusaders, in the early hours of 13 April he also fled, leaving Constantinople abandoned to the control of the Latins.

The sack of Constantinople

Over the centuries Constantinople had become a museum of ancient and Byzantine art. Having secured control of the city the crusaders proceeded to systematically sack and devastate it for three days. Churches and palaces were ransacked. Vast numbers of works of art were stolen, or melted down for their precious metals, or just burned and destroyed. Thousands of citizens were murdered or raped.

Despite the pope’s threat of excommunication, the crusaders destroyed, defiled and looted and set on fire the city’s churches and monasteries. Priests were abused, defrocked or murdered. In the greatest church in Christendom, Hagia Sophia, the crusaders melted down the silver iconostasis, smashed the icons, burned the holy books, and set on the patriarchal throne a prostitute who sang bawdy songs as the crusaders got drunk and pissed on the holy relics.

It was now that the Venetians stole the four statues of horses which they set up over the portico of St Mark’s cathedral in the main square in Venice. A large bronze statue of Hercules, created by the legendary Lysippos, court sculptor of Alexander the Great, was destroyed. Like countless other artworks, the statue was melted down for its metal value.

It was said that the total amount looted from Constantinople was about 900,000 silver marks. After the dust had settled the leaders of the ‘crusade’ made a big pile of their takings and divided up according to a pre-arranged deal. The Venetians took 150,000 silver marks that they reckoned was their due, while the crusaders took 50,000 silver marks. A further 100,000 silver marks were divided evenly up between the crusaders and Venetians. The remaining 500,000 silver marks were kept back by crusader knights and gangs.

When Innocent III heard of the conduct of his crusaders he was beside himself with rage. The whole episode sharply highlights the limits of papal power, and the ineffectiveness of even of the strongest weapon the pope possessed, that of excommunication. Various popes excommunicate numerous kings and emperors and princes throughout Norwich’s book and it never seems to have the slightest effect. In fact I wonder if there is a single example of the threat of excommunication making anyone (anyone of note, any leader) change their behaviour. In his shame the pope wrote:

As for those who were supposed to be seeking the ends of Jesus Christ, not their own ends, who made their swords, which they were supposed to use against the pagans, drip with Christian blood, they have spared neither religion, nor age, nor sex. They have committed incest, adultery, and fornication before the eyes of men. They have exposed both matrons and virgins, even those dedicated to God, to the sordid lusts of boys. Not satisfied with breaking open the imperial treasury and plundering the goods of princes and lesser men, they also laid their hands on the treasures of the churches and, what is more serious, on their very possessions. They have even ripped silver plates from the altars and have hacked them to pieces among themselves. They violated the holy places and have carried off crosses and relics.

The fourth crusaders

The naval attack on Egypt was never carried out. Only a relatively small number of the members of the Fourth Crusade finally reached the Holy Land. About a tenth of the knights who had taken the cross in Flanders arrived to reinforce the remaining Christian states there, plus about half of those from the Île-de-France. What a farce.

The Fourth Crusade – if indeed it can be so described – surpassed even its predecessors in faithlessness and duplicity, in brutality and greed. Constantinople in the twelfth century had been not just the wealthiest metropolis in the world, but also the most intellectually and artistically cultivated and the chief repository of Europe’s classical heritage, both Greek and Roman. By its sack, Western civilisation suffered a loss greater than the sack of Rome by the barbarians in the fifth century or the burning of the library of Alexandria by the soldiers of the Prophet in the seventh – perhaps the most catastrophic single loss in all history. (Norwich, p.182)

The aftermath – a Latin emperor and the Greek successor states

When the looting was quite finished and large parts of the once-glorious city burned to the ground, the crusaders convened to appoint a Latin emperor to take control of the city and the Byzantine Empire. Doge Dandolo wisely withdrew from the field of candidates and Boniface of Montferrat was deliberately rejected because of his family ties with the Greek regime. Several other crusader leaders were overlooked till they settled on the inoffensive Baldwin of Flanders. The Empire was now partitioned:

  • Boniface went on to found the Kingdom of Thessalonica, a vassal state of the new Latin Empire.
  • The Venetians founded the Duchy of the Archipelago in the Aegean Sea.
  • A Duchy of Athens controlling most of Greece.

Byzantine refugees founded their own rump states, namely:

  • the Empire of Nicaea, just across the Bosphorus on the Asian mainland, under Theodore Lascaris (a relative of Alexius III)
  • the Empire of Trebizond far away on the south coast of the Black Sea
  • the Despotate of Epirus on the Dalmatian shore opposite Italy

While Crete, Rhodes, Caphalonia and Corfu were permanently handed over to Venice.

Its enemies take advantage of the ruin of the Byzantine Empire

Norwich’s book takes a decisive turn after the sack of Constantinople. Up till then the reader had a reasonable grasp on the notion of one Byzantine Empire and one Byzantine emperor, who faced a sea of opponents to north, west and east.

But now there were no fewer than four emperors – the Latin one in Constantinople, the Greek one in Nicaea, one in faraway Trebizond and an aspirant one in Epirus (not to mention the Holy Roman Emperor based in Germany). Each of these are led by rulers who aren’t content with their holdings but immediately started scheming against each other, and involving the leaders of the lesser states – the Duchy of Athens, the Principality of Achaea and so on.

For the next fifty years or so, all these characters conspired against each other, fought against each other, made and broke alliances with each other – all the time doing the same with the many enemies who continued to surround and menace the Empire, from the Bulgarians and Serbs in the north, to the Seljuk Turks in the East.

Several of the major Greek and Latin protagonists in the events died or were killed soon after the fall of the city. The betrayal and blinding of Murtzuphlus by Alexius III led to his capture by the Latins and his execution in 1205. Not long after, Alexius III was himself captured by Boniface and sent to exile in Southern Italy. He died in Nicaea in 1211.

On 14 April 1205, one year after the conquest of the city, the Latin emperor Baldwin was decisively defeated and captured at the Battle of Adrianople by the Bulgarians. In 1205 or 1206, the Bulgarian Emperor Kaloyan mutilated him and left him to die (others suggest he was kept captive in the famous Baldwin’s Tower in the Bulgarian capital Veliko Turnovo, where he died under unknown circumstances). Either way, he only lasted a year as the ruler of the Latin Empire and that Empire was to lead a stunted, blighted life, menaced on all sides and deprived of all economic livelihood.

Baldwin was succeeded by his brother Henry of Hainault who appears to have been a wise and fair king, liberal to his Greek subjects, and who – beside battling the troublesome Bulgarians – reached a peace settlement with the Greek Empire based in Nicaea.

The Latin Empire always rested on shaky foundations but it took nearly sixty years before the city was finally retaken by the Nicaean Greeks under Michael VIII Palaeologus in 1261. But it was a ruined wreck of a city, as Norwich’s desolate description makes clear. Many of the churches and palaces still lay abandoned ruins. The population had collapsed. The city was never to recover.

Conclusion

The sack of Constantinople was a major turning point in medieval history. The Crusaders’ decision to attack the world’s largest Christian city was controversial at the time and has been ever since. Reports of Crusader looting and brutality horrified the Orthodox world and crystallised bitter opposition to the barbarian West.

Relations between the Catholic and Orthodox churches were blighted, arguably right up to the present day. Norwich makes the point that, as the Turks drew nearer in the coming centuries, most Byzantines, whether aristocrats or peasants, preferred the idea of subjection by the Muslims to the barbaric destructiveness of the West Europeans. The Byzantines had a saying, ‘Better a turban than a cardinal’s hat,’ and they meant it.

So much for East-West relations, but the main and obvious result of the sack was that the Byzantine Empire was permanently crippled. Broken up into a number of successor states, it was never to be really unified again, never able to muster the resources in men and goods necessary to hold off its enemies, especially the Ottoman Turks who would begin their rise to power 200 years later.

The actions of the Crusaders thus directly accelerated the collapse of Christendom in the East, and in the long run facilitated the expansion of Islam across the Bosphorus and right into the heart of Europe. In 1529 the Ottoman Turks led by Suleiman the Magnificent were to lay siege to Vienna.

So you could argue that the net effect of the entire crusading enterprise was not only to leave an enduring legacy of bitterness throughout the entire Muslim world and among the Greek Orthodox eastern world – but also to hand the Middle East, all of Anatolia and half the Balkans over to Muslim occupiers.

Was ever a mass social movement and religious undertaking so utterly and completely counter-productive?

A Chronology of The Crusades

The Crusades lasted about two hundred years from 1095 to about 1295 and were designed to ‘liberate’ Jerusalem and the Christian Holy Places from the control of Muslim rulers. Although there were later military adventures or social movements which called themselves crusades, they either petered out or were diverted to other targets. Historians squabble over whether there were seven or eight or nine crusades.

Muhammed
632 Muhammed dies.
637 Muslim armies besiege and take Jerusalem from the Byzantine Emperor.

The Great Schism
1054 Eastern and Western Christianity finally split after years of drift, crystallising into the Eastern Orthodox church based in Byzantium and the Roman Catholic church based in Rome, their respective followers known as Latins (or Franks) and Greeks.
1063 King Ramiro I of Aragon murdered by a Muslim and Pope Alexander II offers an indulgence (forgiveness of all sins; go directly to heaven) to anyone taking arms to revenge this crime.
1064-6 – A group of about 7,000 Germans, some heavily armed, travel to Jerusalem and back unhindered.
1073 Pope Gregory VII helps organise an army against the Muslims in Spain, promising any soldier he can keep the land he seizes.
1095 Byzantine Emperor Alexios I sends an ambassador to Pope Urban II asking for military help against the growing Turkish threat (in fact the fast-expanding Great Seljuk Empire). Urban sees an opportunity to reassert Western control over the East and starts preaching a new idea: anyone who takes up arms and travels to liberate the Holy Land under the order of the Pope will go to heaven. Killing the infidel will no longer require penance: it will be a penance.

The First Crusade 1096-99
1096 Easter. Peter the Hermit led a mass of maybe 20,000 people to set off to the Holy Land. As they moved through Germany they sparked off a series of massacres of Jews in every town and city. Having reached the Byzantine Empire they were ambushed by Muslim forces and only about 3,000 survived. Official crusader armies departed Europe August and September 1096.
1097 Siege of Antioch until June 1098. Crusaders massacre the Muslim inhabitants and loot the city.
1099 15 July – CAPTURE OF JERUSALEM The remnants of the army enter/liberate Jerusalem, massacre native Muslims, killing all the Jews, burning the synagogue, looting all the holy buildings. The chronicler claims some 70,000 were slaughtered and the streets piled high with corpses.
1100 On Christmas Day in the Church of the Nativity in Bethlehem, Baldwin of Edessa is crowned King of Jerusalem.

[1101 The Crusade of 1101, also known as The crusade of the faint-hearted due to the involvement of soldiers who had turned back from the First Crusade, was in three distinct groups of western soldiers, all of which were soundly thrashed by Seljuk Turks led by Kilij Arslan. As usual when the crusaders took Caesarea they rounded up all the Muslims into the Grand Mosque and massacred them all. And were then themselves beaten and killed by Kilij. The survivors eventually made it to Jerusalem, more as a pilgrimage than a military force.]

1109 The Franks sack the city of Tripoli after a five year siege, then rampage through it, burning the Banu Ammar library, the largest in the Muslim world, containing over 100,000 manuscripts.
1118 Baldwin dies, succeeded by his cousin, Baldwin II.
1124 Tyre falls to the Franks who now hold the entire cost from Egypt to Antioch.
1131 King Baldwin II dies and is succeeded by his son-in-law, Count Fulk of Anjou.

1122-1124 The Venetian Crusade A combination of religious fervour (it was sponsored by Pope Callixtus II) and commercial savvy, some 120 ships carrying over 15,000 men left Venice on 8 August 1122: they besieged Corfu to settle a commercial dispute; defeated a navy from Fatimid Egypt; besieged and took the sea port of Tyre, which became a Venetian trading centre, and on the way home ravaged various Greek islands, forcing the Empire to concede their trading privileges.

1135 Pope Innocent II’s grant of crusading indulgences to anyone who opposed papal enemies can be seen as the beginning of politically motivated crusades.

The Second Crusade 1145-49
1144 King Fulk dies. Army of Imad ad-Din Zengi recaptures Edessa (modern Urfa), massacring the men and selling the women into slavery. Which leads Pope Eugenius III to call for another crusade, supported by various clerics, notably Bernard of Clairvaux
1146 March 31 – Bernard delivers the first of many thundering first crusade sermons. In May and June armies from France and Germany led by King Louis VII and Conrad III set off.
[1147 A group of crusaders from northern Europe allied with the king of Portugal, Afonso I, retaking Lisbon from the Muslims.]
1147 October 25 – Battle of Dorylaeum: Conrad III and his army of 20,000 men was badly defeated by the Seljuk Turks led by Mesud I. The Germans abandoned the crusade and Conrad and the 2,000 survivors retreated to join the forces of King Louis VII of France.
1148 Louis and Conrad’s surviving soldiers besiege Damascus. It ends in complete defeat and a ruinous retreat. ‘St Bernard’s crusade ended in fiasco.’ (p.93)
1150 Louis and Conrad return home, failures.

The Wendish Crusade
1147 German knights attacked western Slavs on their border with a view to christianising them. Henry restarted efforts to conquer the Wends in 1160, and they were defeated in 1162.

[1172 Henry the Lion, Duke of Saxony, made a pilgrimage that is sometimes considered a crusade.]

Saladin
1169 Saladin – Ṣalāḥ ad-Dīn Yūsuf ibn Ayyūb – a Kurdish Muslim from Damascus, is in complete control of Egypt.
1169-1187 the campaigns of Saladin to unite the usually warring Arab kingdoms.
1180 King Baldwin IV negotiates a peace treaty with Saladin.
1185 24-year-old Baldwin IV dies, leaving the throne of Jerusalem to the eight-year-old Baldwin V.
1186 Baldwin V dies. The kingdom is weakened by complicated dynastic feuds which lead to Guy of Lusignan being crowned king.
1187 SALADIN RETAKES JERUSALEM Saladin led an enormous army of 30,000 into Palestine and inflicted a crushing defeat on the army of Jerusalem at the Battle of Hattin on 4 July. He took his time capturing all the surrounding towns and then retook Jerusalem on 29 September. In studied contrast to the crusader’s massacre and pogrom of 1099, Saladin enforces his army to respect the city and its inhabitants: not a building was looted, not a person harmed.
When Pope Urban III heard the news he died of a heart attack. On 29 October Pope Gregory VIII issued a papal bull calling for the…

The Third Crusade 1189-92
1189 Frederick I ‘Barbarossa’, Holy Roman Emperor, commanded a vast army which sailed to Constantinople, then fought its way across Anatolia, winning battles but suffering from the heat and lack of supplies. Coming down the other side of the Taurus Mountains, Frederick went for a swim in the river Göksu and drowned. His disheartened troops turned back. Philip II of France, and Richard I of England led their armies on to the Holy Land.
1190 Pre-Crusade pogroms of Jews spread across England climaxing in a particularly violent massacre of Jews at York in March.
1191 Richard the Lionheart captured Cyprus from the Byzantines, then recaptured Acre and Jaffa. But they ran out of food before reaching Jerusalem which he knew, anyway, he didn’t have the force to hold.
1192 Richard negotiates a treaty with Saladin allowing Christian pilgrims free passage, then sails home. ‘Jerusalem would never again be captured by crusaders.’ (Crusades p.151) In Palestine Richard had had a big argument with Leopold of Austria. Now, travelling overland back through Leopold’s territory, Richard was identified and arrested. Leopold handed him over to the Emperor Henry VI  who held him in prison for a year before a vast ransom could be organised to buy his freedom.
1193 Saladin dies worn out.
1199 Richard dies of gangrene from an arrow wound at an insignificant siege in Aquitaine.

The German Crusade
1197 Henry VI, Holy Roman Emperor, fulfils a promise to his father. Led by Conrad of Wittelsbach the army landed at Acre and captured Sidon and Beirut, but when Henry died most of the forces returned to Germany.

The North European Crusade
1193  Pope Celestine III called for a crusade against Northern European pagans and his successor Pope Innocent III issued a papal bull declaring a crusade against the pagan Livonians. Bishop Berthold of Hanover led a large army against them, during which the Christian settlers found the city of Riga, although Berthold was himself killed in battle in 1198.
1201 Albrecht von Buxthoeven established Riga as the seat of his bishopric in 1201.
1202 Albrecht formed the Livonian Knights to convert the pagans to Catholicism. The Livonians were conquered and converted between 1202 and 1209.
1217 Pope Honorius III declared a crusade against the Prussians.
1226 Konrad of Masovia gave Chelmno to the Teutonic Knights in 1226 as a base for the crusade.
1236 The Livonian Knights were defeated by the Lithuanians at Saule.
1237 Pope Gregory IX merged the remainder of the troops into the Teutonic Knights as the Livonian Order.
1249 The Teutonic Knights completed their conquest of the Old Prussians. They then conquered and converted the Lithuanians, a process which lasted into the 1380s. The order tried unsuccessfully to conquer Orthodox Russia.

The Fourth Crusade 1202-04 – The Sack of Constantinople
1199 Pope Innocent III began preaching the Fourth Crusade in France, England, and Germany. The two military leaders Doge Enrico Dandolo of Venice and German King Philip of Swabia had their own political agendas and when the enterprise turned out not be able to pay the Venetian fleet, they decided to conquer and loot Constantinople instead.
1202 They seized the Christian city of Zara prompting Innocent to excommunicate them.
1203 Easter – the army set sail for Byzantium.
1204 The army entered Constantinople and enacted the complicated plot to put Prince Alexius IV on the throne. Alexius had promised wild amounts of money in return but turned out to be unable to pay. Alexius was murdered in a palace coup; the blind old emperor died; the coup plotter announced himself emperor. All this made it easier for the Latins and their Catholic leaders to give the go-ahead for a devastating sack of the city, which spread out of control to unbridled looting, massacring, churches pillaged and thousands murdered in the streets.
1205 Bulgars defeated the crusaders and remaining Greeks at Adrianople. The devastation of Byzantium permanently weakened the Eastern Empire, didn’t bring its church under Latin rule, as the Pope dreamed, and probably benefited Venice most, which seized control of commerce in the empire.

The Albigensian Crusade 1208-1229
1208 launched to eliminate the Cathars of Occitania (present-day southern France) lasted for decades and led to Northern French domination of the South. In July 1208 the crusaders took Béziers and massacred every man, woman and child. When soldiers asked the Abbot how they could avoid killing ‘true’ believers, he replied:

‘Kill them all. God will know his own.’

Mindset of terrorists throughout the ages.

[1221 Pope Honorius III asked King Andrew II to put down heretics in Bosnia. Hungarian forces answered further papal calls in 1234 and 1241. This campaign ended with the Mongol invasion of Hungary in 1241.]

The Fifth Crusade 1213-21
1215 Pope Innocent III called the Fourth Council of the Lateran in 1215. It was at this mass assembly of bishops and cardinals that ‘heresy’ was defined, ‘inquisition’ formalised, Jews were ordered to wear special clothing and Innocent announced his new crusade.
1216 Innocent III dies.
1217 Duke Leopold VI and Andrew II arrived in Acre but failed to assert their power and left.
1219 The remaining forces besieged Damietta in Egypt and captured it in November 1219. But further plans were blocked by the Arab leader Ayyubid Sultan Al-Kamil and the crusaders were forced to surrender and hand back Damietta.

The Sixth Crusade b.1228
1228 Holy Roman Emperor Frederick II, after being repeatedly threatened and eventually excommunicated by Innocent’s successor, Pope Honorius III, for his delays, finally landed at Acre.
1229 RESTORATION OF JERUSALEM – However, both sides being reluctant to fight, Frederick agreed a peace treaty with Al-Kamil which allowed Latin Christians to rule most of Jerusalem and a strip of land along the coast, with the Muslims controlling their sacred areas in Jerusalem. Frederick had himself crowned in the Holy Sepulchre and declared himself the mouthpiece of God. Frederick returned home to find the Pope had organised armies to invade his realm.
1238 Frederick tried to extend his lands into northern Italy and Pope Gregory declared a crusade against him. ‘The Holy War was now being preached not against the ‘infidel’, not even against a heretic – no such charge was made against Frederick – but against a political enemy of the Pope.’ (Crusades p.181) Crusade had become degraded to a purely secular concept.

1239 A force led by King Theobald I of Navarre arrived in Acre in September. Defeated in battle in November, Theobald negotiated another treaty with the Ayyubid Sultan Al-Kamil.

1244 THE DESTRUCTION OF JERUSALEM
The Ayyubids invited Khwarazmian forces whose empire had been destroyed by Genghiz Khan’s Mongols, to reconquer the city. It fell July 15, 1244 and the Khwarezmians completely razed Jerusalem to the ground, leaving it in ruins.
1244 An Arab force led by al-Salih Ayyub seized Jerusalem.

The Seventh Crusade 1248-1254
1245-50 King Louis IX of France organized a vast army, set sail in 1248 and landed in Egypt in June 1249. In a series of battles they were defeated, and in 1250 Louis was captured and ransomed for 800,000 bezants, and a ten-year truce agreed.
1254 Louis withdrew to Acre, now the only Crusader territory of any significance, which he built up again until his money ran out in 1254 and he had to return to France.

[1256 The Venetians were evicted from Tyre, prompting the War of Saint Sabas over territory in Acre claimed by Genoa and Venice. The war dragged on for a decade during which both Christian sides allied with Muslim forces and most fortified buildings in Acre were destroyed.
1266 Louis IX’s brother Charles seized Sicily and other parts of the eastern Mediterranean with a view to restoring the Latin empire by reconquering Byzantium.]

The Eighth Crusade 1270
1265 The ferocious Mameluk Sultan Baibars ibn-Abdullah had captured Caesarea, Nazareth, Haifa, Safed, Toron, and Arsuf.
1268 Baibars captures Antioch and massacres its entire population.
1270 These events inspire King Louis IX of France to sail to Tunis with a large fleet and impressive army. However it was the height of the Saharan summer, the army was devastated by disease and Louis died. Thus ended the last major attempt to take the Holy Land.

The Ninth Crusade 1272
1270 The future Edward I of England had travelled with Louis. He sailed with his forces to Acre in May 1271. His forces were small and he was unable to alter the existing peace treaties between Baibars and King Hugh of Jerusalem.
1272 Edward learned of his father’s death.
1274 Edward I returns to England to take up his crown.
1277 The fearsome Baibars dies.

Last crusade
1281 Election of a French pope, Martin IV who threw himself behind the campaigns of French king Charles I. His ships were at Sicily when the Emperor of Byzantium conspired to provoke the ‘Sicilian Vespers’, an uprising during which the crusader fleet was abandoned and burnt.
1287 King Charles I dies, allowing Henry II of Cyprus to reclaim Jerusalem.

These kinds of struggles are typical of the endless disunity and conflict among the Roman Christians which continually undermined efforts to hold the Holy Land. In this two hundred year period the papacy, far from creating the kind of total control over Christendom which Innocent and Urban dreamed of, had become just one among a hectic throng of nationalist kings and princes all fighting each other. The papacy had lost all its moral authority. Thus:

1284 The Crusade of Aragon was called by Pope Martin against Peter III of Aragon, Peter supporting anti-Angevin forces in Sicily, Martin supporting Charles of Anjou.
1298 Pope Boniface VIII proclaimed a crusade against Frederick III of Sicily (Peter’s younger brother).

THE END OF THE CRUSADER STATES
1291 A group of pilgrims from Acre was attacked by Muslim forces and in retaliations killed some innocent Muslim merchants. The Sultan demanded compensation from the king of Acre and, when none came, used it as a pretext to besiege and then capture the city. Men, women and children were massacred: prisoners were beheaded. Acre had been the last independent Crusader state in the Holy Land and its fall signified that – The Crusades had ended.


Non-Holy Land ‘crusades’

1365 The Alexandrian Crusade Peter I of Cyprus captured and sacked Alexandria for mainly commercial reasons, killing as many Christians as Muslims and Jews.
1390 The Mahdian Crusade Louis II led a ten-week campaign against Muslim pirates in North Africa. After a siege the crusaders signed a ten-year truce.
1396 Crusade against the Ottomans led by Sigismund of Luxemburg, king of Hungary which was defeated by the Ottomans in the Battle of Nicopolis.

1420s The Hussite Crusades military action against the followers of Jan Hus in Bohemia from 1420 to about 1431. Crusades were declared five times during that period: in 1420, 1421, 1422, 1427, and 1431.
1440s Crusade against the Ottomans Polish-Hungarian King Władysław Warneńczyk invaded recently conquered Ottoman territory, reaching Belgrade in January 1444. Negotiated a truce with Sultan Murad II. The Ottomans won a decisive victory at the Battle of Varna on 10 November, and the crusaders withdrew. This left Constantinople exposed and it fell to the Ottoman Turks in 1453.

John Hunyadi and Giovanni da Capistrano organized a 1456 crusade to lift the Ottomon siege of Belgrade.
1487 Pope Innocent VIII called for a crusade against the Waldensians in the south of France but little military activity followed and it had no effect…
