 The line of Beauchamps Earls ended in 1449 when Anne de Beauchamp, 15th Countess of Warwick, died. Richard Neville became the next Earl of Warwick through his wife's inheritance of the title. During the summer of 1469, Neville rebelled against King Edward IV and imprisoned him in Warwick Castle. Neville attempted to rule in the king's name; however, constant protests by the king's supporters forced the Earl to release the king. Neville was subsequently killed in the Battle of Barnet, fighting against King Edward IV in 1471 during the Wars of the Roses. Warwick Castle then passed from Neville to his son-in-law, George Plantagenet, 1st Duke of Clarence. George Plantagenet was executed in 1478 and his lands passed onto Edward Plantagenet, 17th Earl of Warwick; however, Edward Plantagenet was only two when his father died so his lands were taken in the custody of The Crown. He was placed under attainder, and so could not inherit the throne, by Henry VII, being held by Henry for fourteen years in the Tower of London until he was executed for high treason in 1499, supposedly for conspiring to escape with the' pretender 'Perkin Warbeck. Edward was the last Earl of Warwick of the title's first creation.
