Clarence, George, Duke of 1449-78
English nobleman

Born in Dublin, Ireland, he was the third son of Richard, Duke of York, and brother of Edward IV and Richard III. He was created Duke of Clarence on Edward's accession (1461). He married Isabella, elder daughter of Richard Neville, Earl of Warwick, against Edward's wishes (1469), and supported Warwick against his brother in the brief restoration of Henry VI (1470), but deserted to his brother's side (1471). He quarrelled with his other brother, Richard, Duke of Gloucester, over Richard's marriage to his sister-in-law Anne Neville (1472), but was later reconciled. In 1478 he was impeached by his brothers for treason, and secretly executed. According to tradition, he was put to death in the Tower of London, drowned in a butt of malmsey wine. Despite his traditionally bad historical reputation, he had many of the good qualities of his time.
