In 1450 Normandy was lost, the rebellion of Jack Cade against the misgovernment of the nobles took place, and Richard, Duke of York, began to be prominent. The queen's favourite, was, however, the Duke of Somerset, and York became Regent of Ireland. From thence he returned and insisted on a reform in the Council, which was granted. In 1453 Guienne was lost, and in the same year the king showing signs of mental weakness, a struggle for the Protectorate began between Somerset and York. The latter was appointed early in 1454, but the king soon recovered. Next year the Wars of the Roses began, and after his victory at St. Albans York became again Protector for four years. The struggle was renewed in 1459, and York was attainted at Coventry by a Lancastrian Parliament.
In the following year, however, he won a victory at Northampton, after which he claimed the crown; but the queen raised an army in the north, and at Wakefield the Duke was defeated and slain. The battle of Towton (March, 1461) put a period to the Lancastrian triumph, and Henry was dethroned and imprisoned. He was temporarily restored by Warwick ten years later, but after the final Yorkist victories of Barnet and Tewkesbury was put to death, as was popularly supposed, by the hand of the youngest son of the late Duke of York.
