who was the first known king of england
List of English monarchs Arguments are made for a few different kings deemed to control enough of the ancient kingdoms of the Anglo-Saxons to be deemed the first King of England. For example, Offa, king of Mercia, and Egbert, king of Wessex, are sometimes described as kings of England by popular writers, but not by all historians.[citation needed] In the late eighth century Offa achieved a dominance over southern England that did not survive his death in 796. In 829 Egbert conquered Mercia, but he soon lost control of it. By the late ninth century Wessex was the dominant Anglo-Saxon kingdom. Its king, Alfred the Great, was overlord of western Mercia and used the title King of the Angles and Saxons, but he never ruled eastern and northern England, which was then the Danelaw. His son Edward the Elder conquered the eastern Danelaw, but Edward's son Æthelstan became the first king to rule the whole of England when he conquered Northumbria in 927, and he is regarded by some modern historians as the first king of England.[2][3]
