English nobleman, second husband of Mary, Queen of Scots , and father of James I .
Son of Matthew Stewart, earl of Lennox (1516–71), a pretender to the Scottish throne, Henry wed his cousin Mary in 1565 despite the opposition of Elizabeth I and Scottish Protestants. It became evident, even to Mary, that superficial charm was his only positive attribute. After he played a role in the murder of Mary's secretary, David Riccio , he was himself murdered at age 21 at the instigation of James Hepburn, earl of Bothwell (1535–78), whom Mary soon married.
