Edward built on his father Alfred's successes by gaining control of most of Wales and the Danish territories south of the Humber. He was recognized as overlord by York, Scotia and Strathclyde. Although Mercia was frequently in a state of unrest he managed to annexe it in 918. The year after his death this enabled his son Athelstan to be crowned King of all the English.
