Wars of the Roses

Thirty-two years of intermittent civil war between the Lancastrian and Yorkist branches of the Plantagenet dynasty, triggered by the recurring incapacity of Henry VI and the rival claim of Richard, Duke of York. The conflict produced six battles in the 1450s–1460s, the murderous reign of Edward IV, the disappearance of his sons in the Tower, and the final defeat of Richard III at Bosworth in 1485. Resolved by the marriage of Henry VII and Elizabeth of York the following year.
