Alexander II, king of Scotland
11981249, king of Scotland (121449), son and successor of William the Lion. He joined the English barons in their revolt against King John of England in 1215. Though he made his peace with Johns successor, Henry III, in 1221, there was later friction that almost led to war. In 1237, Alexander agreed to give up his claims to overlordship in old Northumbria and to exchange lands he held in central England for lands in the north. At home Alexander was firm in quelling disorder.
