In 449 (according to Bede), Vortigern invited the Angles to Britain to help fight off Picts and Scots.

King Hygelac died around 521 in a raid on what is now the Netherlands.

Anglo-Saxons converted to Christianity around 590’s (Christianity had been introduced by the Romans earlier on but the new religion was fused with the old heroic ideals)

Scholars think there was a time gap of a couple hundred years between conversion and the composition of the Beowulf poem. It was probably written sometime between 700 and 900.
