Athelbald of Wessex
Athelbald, also spelled Æthelbald or Ethelbald (–860) was a West Saxon nobleman. In 856 he was King of Wessex while his father was in Rome. When Athelwulf returned, Athelbald refused to step down. To avoid a civil war, Athelwulf gave his son the kingdom of Wessex and became sub-king of Kent.
