Edward IV (28 April 1442 – 9 April 1483) was the King of England from 4 March 1461 until 3 October 1470, and again from 11 April 1471 until his death in 1483. He was the first Yorkist King of England. The first half of his rule was marred by the violence associated with the Wars of the Roses, but he overcame the Lancastrian challenge to the throne at Tewkesbury in 1471 to reign in peace until his sudden death. His son was Edward V, one of the princes in the tower, probably murdered by his brother Richard III.
