Battle of Towton: Edward of York defeats Queen Margaret to become King Edward IV of England, bringing a temporary stop to the Wars of the Roses.

The Battle of Towton took place on 29 March 1461 during the Wars of the Roses, near Towton in North Yorkshire. Yorkist forces decisively defeated Lancastrian supporters of Henry VI, securing the English throne for Edward IV. Fought for ten hours between an estimated 50,000 soldiers from both sides in a snowstorm on Palm Sunday, it was "probably the largest and bloodiest battle on English soil".

Edward IV was King of England from 4 March 1461 to 3 October 1470, then again from 11 April 1471 until his death in 1483. He was a central figure in the Wars of the Roses, a series of civil wars in England fought between the Yorkist and Lancastrian factions between 1455 and 1487.

Margaret of Anjou was Queen of England by marriage to King Henry VI from 1445 to 1461 and again from 1470 to 1471. Through marriage, she was also nominally Queen of France from 1445 to 1453. Born in the Duchy of Lorraine into the House of Valois-Anjou, Margaret was the second eldest daughter of René of Anjou, King of Naples, and Isabella, Duchess of Lorraine.

The Wars of the Roses, known at the time and in following centuries as the Civil Wars, and also the Cousins' War, were a series of armed confrontations, machinations, battles and campaigns fought over control of the English throne from 1455 to 1487. The conflict was fought between supporters of the House of Lancaster and House of York, two rival cadet branches of the royal House of Plantagenet. The conflict resulted in the end of Lancaster's male line in 1471, leaving the Tudor family to inherit their claim to the throne through the female line. Conflict was largely brought to an end upon the union of the two houses through marriage, creating the Tudor dynasty that would subsequently rule England.
