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.

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…
