Alexander III of Scotland

Alexander III (1241–1286), son of Alexander II and Marie de Coucy, succeeded in 1249 aged seven and was crowned at Scone. In 1251 he married Margaret, daughter of Henry III, but refused homage for Scotland. He claimed the Western Isles from Norway; Haakon IV invaded in 1263, but a storm damaged his ships and the Battle of Largs was indecisive.

By the Treaty of Perth in 1266 Scotland gained the Hebrides and Man. When his children died, his granddaughter Margaret, Maid of Norway, was named heir in 1284. He died in a riding fall at Kinghorn in 1286.
