Douglas, Archibald, 6th earl of Angus, 1489–1557, Scottish nobleman; grandson of Archibald Douglas, 5th earl of Douglas. His marriage (1514) to Margaret Tudor alienated the Scottish noblemen and caused Margaret to lose the regency to John Stuart, duke of Albany. A struggle for control of the young James V ensued between Angus and Albany, with James's mother, Margaret, favoring first her husband, then Albany. In 1526, Angus seized the young king and held him until James escaped in 1528. Margaret had meanwhile (1527) divorced Angus, and, deprived of his lands because of his alliance with Henry VIII, he left for England. After King James's death in 1542, Angus returned to Scotland, was restored to power, and was soon fighting against England. But he continued to correspond with Henry and to contest the power both of the regent James Hamilton, earl of Arran, and his successor, the dowager queen, Mary of Guise.
