Margaret Tudor (28 November 1489 – 18 October 1541) was Queen of Scots from 1503 until 1513 as the wife of King James IV of Scotland and then Regent for their son King James V. She was born at Westminster Palace as the elder surviving daughter of King Henry VII of England and Elizabeth of York. As Queen Dowager (Queen Mother) she married Archibald Douglas, 6th Earl of Angus. Through her first and second marriages, respectively, Margaret was the grandmother of both Mary, Queen of Scots, and Mary's second husband, Lord Darnley. Margaret's marriage to James IV foreshadowed the Union of the Crowns – their great-grandson, King James VI of Scotland, the child of Mary and Darnley, became King James I of England and Ireland on the death of Margaret's fraternal niece, Queen Elizabeth I of England in 1603.
