The following timeline is not exhaustive, but does provide a rough overview of events during the Anglo-Saxon period.

AD 449 The traditional date for the arrival of the Anglo-Saxon invaders of Britain taken from the ‘Ecclesiastical History of the English’, by the Venerable Bede. It is almost certainly wrong.

AD 565 Columba founds a monastery on the Scottish island of Iona
AD 597 Augustine arrives in Kent and begins the conversion of England
AD 616 Æthelberht, the first Christian English king, dies in Kent. One of his lasting legacies was his law code, the first written in English.
AD 627 Edwin of Northumbria becomes the first Christian king in the north of England
AD 633 Aidan founds the monastery of Lindisfarne, Northumbria
AD 642 Oswald of Northumbria dies a Christian martyr in battle. His relics were said to work miracles as far afield as southern Germany.
AD 664 Oswiu, king of Northumbria, called a meeting at Whitby to settle which church practices should have precedence in his kingdom – those of the Celtic church or the Roman church. The matters discussed included how to calculate the date of Easter. It was decided to follow the practice of Rome. As a result, many Irish clergy left Northumbria and returned to Ireland.

AD 869 Edmund, King of the East Angles, is martyred by the Vikings. He was beheaded and his head thrown away to prevent proper burial. Much later, his head was finally reunited with the body, and both were buried in the royal residence, which later became known as Bury St Edmunds.
AD 871 A series of bloody clashes between the Vikings and the kingdom of Wessex, under Æthelred and his brother Alfred, at Reading, Ashdown, Basing and elsewhere. None were decisive. Æthelred died during the campaign and Alfred became king of Wessex.
