List of Famous people named Offa

Offa was King of Mercia, a kingdom of Anglo-Saxon England, from 757 until his death in July 796. The son of Thingfrith and a descendant of Eowa, Offa came to the throne after a period of civil war following the assassination of Æthelbald. Offa defeated the other claimant, Beornred. In the early years of Offa's reign, it is likely that he consolidated his control of Midland peoples such as the Hwicce and the Magonsæte. Taking advantage of instability in the kingdom of Kent to establish himself as overlord, Offa also controlled Sussex by 771, though his authority did not remain unchallenged in either territory. In the 780s he extended Mercian Supremacy over most of southern England, allying with Beorhtric of Wessex, who married Offa's daughter Eadburh, and regained complete control of the southeast. He also became the overlord of East Anglia and had King Æthelberht II of East Anglia beheaded in 794, perhaps for rebelling against him.

Offa was King of Essex. D. H. Kirby dates his reign as 705 to 709. Simon Keynes dates it c.694 to 709, when he went on a pilgrimage to Rome, where he died as a monk, along with Cenred, King of Mercia. He may have been co-king with Swæfred. He was the son of Sighere, who had died in about 690.
