A Dark Age Chronology

Inspired by Robert Ferguson’s brilliant book, The Hammer and The Cross, I collated key dates from the so-called Dark Ages (let’s say from the departure of the Romans from Britain in 410 to the Norman Conquest of 1066). Why? Why not?

An at-a-glance summary of the period would be:

  • 400 Romans leave England
  • 450 Angles and Saxons invade Christian Britain
  • 500 Anglo-Saxon kingdoms exist all across Britain, the Heptarchy
  • 600 St Augustine comes as missionary to the pagan Anglo-Saxons
  • 800 Vikings attack Lindisfarne, going on to colonise east and north England: a century of battles
  • 900 Alfred the Great and successors unify the Anglo-Saxons against the Danes, creating ‘England’
  • 1000 Aethelred the Unready fails to deal with repeated Viking attacks
  • 1100 England conquered and ruled by the Norman French

5th century

410 Traditional date for the Romans quitting Britain. In fact it was a gradual process: 407 the army elects Constantine III emperor and he takes a lot of the Roman army to Gaul to attack Honorius: how many? was a military commander left or ever reappointed?

408 A Saxon attack repelled by Britons.

409 Zosimus records the natives expelled the Roman administration.

410 the rescript of Honorius – apparently the emperor Honorius telling the Britons they are on their own facing barbarian attacks.

449 (a retrospectively written section of) the Anglo-Saxon Chronicle says Hengest and Horsa lead Saxons, Jutes and Angles to Kent at King Vortigern’s request to protect from marauding Picts, and decide to stay: the official start of Anglo-Saxon England. The venerable Bede attributes the date of 449. Their names mean ‘stallion’ and ‘horse’, respectively: were they real people or legendary symbols?
