lexander III, 1241-86, king of Scotland (1249-86),
son and successor of Alexander II. He married a daughter of Henry
III of England and disputed with him over the old English claims
to overlordship in Scotland. The great achievement of Alexander
was his final acquisition for Scotland of the Western Islands and
of the Isle of Man, which his father had already claimed from
Norway. To drive the Scots from the islands King Haakon IV of
Norway sailed with a great fleet in 1263, but a storm battered
his ships, and he fought the inconclusive battle of Largs in the
River Clyde (1263). Alexander signed a treaty with Haakons
successor, Magnus VI, assigning the Western Isles and the Isle of
Man to Scotland. This was followed by an arrangement with Norway
providing for the marriage of Magnuss son Eric with
Alexanders daughter Margaret. Alexander survived his
children, and when he died his only near relative was his little
granddaughter Margaret Maid of Norway. See biography by James
Fergusson (1937). [The Illustrated Columbia Encyclopedia, 1969]
