King Offa (757 - 796)

Offa (son of Thingfrith, son of Eanulf), King of Mercia, was one of the leading figures of Saxon history. He obtained the throne of Mercia in 757, after the murder of his cousin, King Aethelbald, by Beornraed. After spending fourteen years in consolidating and ordering his territories he engaged in conquests which made him the most powerful king in England. After a successful campaign against the Hestingi, he defeated the men of Kent at Otford (776); the West Saxons at Bensington in Oxfordshire (779); and finally the Welsh, depriving the last-named of a large part of Powys, including the town of Pengwern. To repress the raids of the Welsh he built Offa's dyke, 150 miles long and roughly indicating for the first time what has remained the boundary between England and Wales.

From 776 Offa was the most powerful Anglo-Saxon king until Alfred the Great. He ruled over Kent, Sussex, East Anglia and the Midlands, and allied with Beorhtric of Wessex. His rule never extended to Northumbria but his daughter married the King of Northumbria. Offa died in 796.
