Battle of Rowley Burn, 633
Battle in late 633 at which Oswald, brother of Æthelfrith king of Northumbria, killed Cadwallon, king of Gwynedd, who had previously defeated and killed Edwin, king of Northumbria. Oswald became king of Northumbria after the battle. Cadwallon was the only British king to destroy an English dynasty, and his death weakened the Britons.
