Egbert

Egbert became king of Wessex in 800, in succession to the usurper Brihtric, who had compelled him to take refuge at the courts of Offa, King of Mercia, and the Emperor Charlemagne successively. In 827 he subdued the other kingdoms, and reigned as king of all England till his death ten years later. The Danish invaders gave him much trouble in the latter part of his reign.
