Aethelbald

King of the Mercians from 716, who became the chief king of a confederation including all the Anglo-Saxon kingdoms between the River Humber and the English Channel. His predominance was made possible by the death of the strong king Wihtred of Kent (725) and the abdication of Ine of Wessex (726). During Aethelbald's reign, London passed from East Saxon to Mercian control.
