Ecgberht, King of Wessex [SEP] Introduction
When Ecgberht died in 839, Æthelwulf succeeded him; the southeastern kingdoms were finally absorbed into the kingdom of Wessex after the death of Æthelwulf's son Æthelbald in 860. Ecgbert's descendants ruled Wessex and, later, all of England continuously until 1013.
