Alexander I, 1078?–1124, king of Scotland (1107–24), son of Malcolm III and St. Margaret of Scotland. He succeeded his brother Edgar, who had divided the kingdom so that Alexander ruled only N of the Forth and Clyde rivers, while his brother David ruled in the south. Early in his reign he decisively quelled an uprising in N Scotland. Like his mother, Alexander encouraged ecclesiastical conformity with English ways and established several monasteries, including the abbeys at Inchcolm and Scone. David succeeded him as David I.
