644• Oswine, son of the late king Osric of Deira, manages despite armed objections from king Oswiu of Bernicia, to establish himself as king of Deira (Northern England). His succession, probably the choice of the people of Deira, splits the Kingdom of Northumbria.[http://www.newadvent.org/cathen/11349a.htm Parker, Anselm. "St. Oswin". The Catholic Encyclopedia.
