Richard of York, 3rd Duke of York (21 September 141130 December 1460), also named Richard Plantagenet, was a leading English magnate and claimant to the throne during the Wars of the Roses. He was a member of the ruling House of Plantagenet by virtue of being a direct male line descendant of Edmund of Langley, Edward III’s fourth surviving son. However, it was through his mother, Anne Mortimer, a descendant of Edward III’s second surviving son, Lionel of Antwerp, that Richard inherited his strongest claim to the throne. He also inherited vast estates and served in various offices of state in Ireland, France, and England, a country he ultimately governed as Lord Protector during the madness of King Henry VI.

His conflicts with Henry's wife, Margaret of Anjou, and other members of Henry's court, as well as his competing claim to the throne, were leading factors in the political upheaval of mid-fifteenth-century England, and a major cause of the Wars of the Roses. Richard eventually attempted to take the throne, but was dissuaded, although it was agreed that he would become king on Henry's death. However, within a few weeks of securing this agreement, the Act of Accord, he died in the Battle of Wakefield. Two of his sons, Edward IV and Richard III, later ascended the throne.
