Offa was King of Mercia, a kingdom of Anglo-Saxon England, from 757 until his death. 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.
Coenwulf was the King of Mercia from December 796 until his death in 821. He was a descendant of a sibling of King Penda, who had ruled Mercia in the middle of the 7th century. He succeeded Ecgfrith, the son of Offa; Ecgfrith only reigned for five months, and Coenwulf ascended the throne in the same year that Offa died. In the early years of Coenwulf's reign he had to deal with a revolt in Kent, which had been under Offa's control. Eadberht Præn returned from exile in Francia to claim the Kentish throne, and Coenwulf was forced to wait for papal support before he could intervene. When Pope Leo III agreed to anathematise Eadberht, Coenwulf invaded and retook the kingdom; Eadberht was taken prisoner, was blinded, and had his hands cut off. Coenwulf also appears to have lost control of the kingdom of East Anglia during the early part of his reign, as an independent coinage appears under King Eadwald. Coenwulf's coinage reappears in 805, indicating that the kingdom was again under Mercian control. Several campaigns of Coenwulf's against the Welsh are recorded, but only one conflict with Northumbria, in 801, though it is likely that Coenwulf continued to support the opponents of the Northumbrian king Eardwulf.
Ecgfrith was king of Mercia from 29 July to December 796. He was the son of Offa, one of the most powerful kings of Mercia, and Cynethryth, his wife. In 787, Ecgfrith was consecrated king, the first known consecration of an English king, probably arranged by Offa in imitation of the consecration of Charlemagne's sons by the pope in 781. Around 789, Offa seems to have intended that Ecgfrith marry the Frankish king Charlemagne's daughter Bertha, but Charlemagne was outraged by the request and the proposal never went forward.
Eanbald was an eighth century Archbishop of York.
Eardwulf was king of Northumbria from 796 to 806, when he was deposed and went into exile. He may have had a second reign from 808 until perhaps 811 or 830. Northumbria in the last years of the eighth century was the scene of dynastic strife between several noble families: in 790, king Æthelred I attempted to have Eardwulf assassinated. Eardwulf's survival may have been viewed as a sign of divine favour. A group of nobles conspired to assassinate Æthelred in April 796 and he was succeeded by Osbald: Osbald's reign lasted only twenty-seven days before he was deposed and Eardwulf became king on 14 May 796.
