House of York Warwick himself changed sides, and supported Margaret of Anjou and the king's jealous brother George, Duke of Clarence, in briefly restoring Henry in 1470-71. However, Edward regained his throne, and the House of Lancaster was wiped out with the death of Henry VI himself, in the Tower of London in 1471. In 1478, the continued trouble caused by Clarence led to his execution in the Tower of London; popularly he is thought to have been drowned in a butt of malmsey wine. On Edward's death in 1483, the crown passed to his twelve-year-old son Edward. Edward IV's younger brother Richard,
Edward IV of England Richard, Duke of Gloucester (later King Richard III of England), were married to Isabel Neville and Anne Neville. Both were daughters of Warwick by Anne Beauchamp and rival heirs to the considerable inheritance of their still-living mother, leading to a dispute between the brothers. In 1478 George was eventually found guilty of plotting against Edward, imprisoned in the Tower of London, and privately executed on 18 February 1478. According to a long-standing tradition, he was "drowned in a butt of Malmsey wine". Edward did not face any further rebellions after his restoration, as the Lancastrian line had virtually been extinguished.
