Kingdom of the East Angles in the context of "King Offa"

The Heptarchy was the division of Anglo-Saxon England between the sixth and eighth centuries into petty kingdoms, conventionally the seven kingdoms of East Anglia, Essex, Kent, Mercia, Northumbria, Sussex, and Wessex. The term originated with the twelfth-century historian Henry of Huntingdon and has been widely used ever since, but it has been questioned by historians as the number of kingdoms fluctuated, and there was never a time when the territory of the Anglo-Saxons was divided into seven kingdoms each ruled by one king. The period of petty kingdoms came to an end in the eighth century, when England was divided into the four dominant kingdoms of East Anglia, Mercia, Northumbria, and Wessex.

Offa (c. 730 – 29 July 796 AD) was King of Mercia, a kingdom of Anglo-Saxon England, from 757 until his death in 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 a Christian king who came into conflict with the Church, particularly with Jænberht, the Archbishop of Canterbury. Offa persuaded Pope Adrian I to divide the archdiocese of Canterbury in two, creating a new archdiocese of Lichfield. This reduction in the power of Canterbury may have been motivated by Offa's desire to have an archbishop consecrate his son Ecgfrith as king, since it is possible Jænberht refused to perform the ceremony, which took place in 787. Offa had a dispute with the Bishop of Worcester, which was settled at the Council of Brentford in 781.
