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.
