Queen of Scotland (1286–90). She was the daughter of Erik II, King of Norway, and the granddaughter of Alexander III of Scotland. She became Queen of Scotland at the age of three, although six guardians were appointed to govern the kingdom during her minority. Edward I of England proposed a marriage between Margaret and his son Edward, the first English Prince of Wales. Her death when crossing the North Sea from Norway to Scotland brought to an end the dynastic House of Canmore, which had ruled since 1057, and led to a dispute (1291–92) over the succession involving 13 claimants. Edward I of England judged in favour of John Balliol.
