Cenwalh of Wessex
Cenwalh was the son of King Cynegils. When his father died in 643 Cenwalh succeeded him as king of Wessex. He married a sister of Penda of Mercia who was the power in the region at that time. When Cenwalh repudiated her (set her aside) in favor of another wife, Penda invaded Wessex. Penda drove Cenwalh into exile in East Anglia. He remained in East Anglia for three years with King Anna of East Anglia. There he learned about Christianity and was baptised. While in exile, Wulfhere, the son of Penda, took a great deal of territory away from Wessex. He gave the Isle of Wight to Aethelwalh, King of Sussex.
