queen of Scotland from 1286 to 1290, the last of the line of Scottish rulers descended from King Malcolm III Canmore (ruled 1058–93).

Margaret's father was Eric II, king of Norway; her mother, Margaret, a daughter of King Alexander III of Scotland (ruled 1249–86), died in 1283. Because none of Alexander III's other children were alive at the time of his death (March 1286), the Scottish lords proclaimed the infant Margaret as their queen. In 1290 her great-uncle, King Edward I of England, arranged a marriage between Margaret and his son Edward, later King Edward II of England. On the voyage from Norway to England, however, Margaret fell ill and died. Although the marriage treaty had specified that Scotland was to maintain its independence of England, Edward now proclaimed himself overlord of Scotland; the Scots resisted, and for more than 20 years Scotland suffered foreign domination and civil war.
