Act of Accord

After unsuccessfully claiming his right to the crown in parliament on 10 October 1460, Richard, duke of York, had to accept the Act of Accord on 25 October 1460, which stipulated that he would be the heir to the throne after King Henry VI’s death, instead of the king’s son, Edward of Lancaster.

His claim was that while on his father’s side he was descended from Edward III’s fourth son, on his mother’s side he was descended from Edward III’s son.  The Lancastrian Kings including Henry VI, however, were descendents of the third son of Edward III.

While the Duke of York’s claim ultimately failed, it was the basis for his son Edward IV to succeed to the crown.
