James Hamilton, 3rd Earl of Arran
James Hamilton, 3rd Earl of Arran (c. 1532–1609) was a Scottish nobleman and soldier who opposed the French-dominated regency during the Scottish Reformation. He was the eldest son of James Hamilton, 2nd Earl of Arran, sometime Regent of Scotland. He was of royal descent, and at times was third or fourth in succession to the Scottish crown; several royal marriages were proposed for him. He went to France with Mary, Queen of Scots, and commanded the Scots Guards. After returning to Scotland, he became a leader of the Protestant party against Mary and her French supporters, but went insane in 1562 and was confined in seclusion for the rest of his life.
