Oswiu

Oswiu ( d. 670), king of Northumbria (642-70). Ruling Bernicia, Oswiu was responsible for the death of the Deiran king Oswin (651), his wife's kinsman. Oswin's successor allied with the powerful Mercian king Penda, who attacked in 655, but was defeated and killed at the battle of Winwæd, near Leeds. Oswiu fulfilled his promise that, if victorious, he would grant twelve estates for monasteries and dedicate his infant daughter to God's service. He used his influence to convert the Mercian prince, Peada, and revive East Saxon Christianity.
