Edward IV was King of England from March 4, 1461 to April 9, 1483, with a break of a few months in the period 1470–1471.

Edward of York was born on April 28, 1442 at Rouen in France, the second son of Richard Plantagenet, 3rd Duke of York (a leading claimant to the throne of England) and Cecily Neville. York's challenge to the ruling family marked the beginning of the conflict known as the Wars of the Roses. When his father was killed in 1460 at the Battle of Wakefield, pressing his claim against the Lancastrian king Henry VI of England, Edward inherited his claim.

With the support of Richard Neville, 16th Earl of Warwick ("The Kingmaker"), Edward, already showing great promise as a leader of men, defeated the Lancastrians in a succession of battles. While Henry and his militant queen, Margaret of Anjou, were campaigning in the north, Warwick gained control of the capital and had Edward declared king in London in 1461. Edward strengthened his claim with a decisive victory at the Battle of Towton in the same year, in the course of which the Lancastrian army was virtually wiped out.

Edward fell ill at Easter 1483, but lingered on long enough to add some codicils to his will, the most important being his naming of his brother Gloucester as Protector after his death. He died on 9 April 1483 and is buried in St George's Chapel, Windsor Castle. He was succeeded by his twelve-year-old son, Edward V of England.
