The Nevilles 1449 – 1486 AD

Richard Beauchamp's vast inheritance passed to his sister Ann. Ann had married Richard Neville, who was created Earl of Warwick in 1450, when he became of age, and entered politics two years later, declaring his support for Richard of York against Henry VI (who had greatly honoured his wife's family) in 1455.

'Warwick the King-maker', as he was later to be known, was ambitious much concerned with territorial interests. He was also heavily involved in the Wars of the Roses, but he was killed in battle in 1471.

Richard Neville had two daughters and it was through his younger daughter, Ann that Cardiff Castle passed to her husband Richard, Duke of Gloucester (afterwards King Richard III) who succeeded to the Lordship of Cardiff. Richard of Gloucester ascended the throne. His agent in Glamorgan, Sir James Tyrell, was made Constable of Cardiff Castle, and it was Tyrell who is suspected of the murder of the two young Princes in the Tower of London.
