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 for control of the English throne from 1455 to 1487. The conflict was fought between supporters of the House of Lancaster (emblem a red rose) and House of York (white rose), 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.
The Wars of the Roses were rooted in English socio-economic troubles caused by the Hundred Years' War (1337–1453) with France, as well as the quasi-military bastard feudalism resulting from the powerful duchies created by King Edward III. The mental instability of King Henry VI of the House of Lancaster revived his cousin Richard, Duke of York's interest in a claim to the throne. Warfare began in 1455 with York's capture of Henry at the First Battle of St Albans, upon which York was appointed Lord Protector by Parliament. Fighting resumed four years later when Yorkists led by Richard Neville, Earl of Warwick, captured Henry again at the Battle of Northampton. After attempting to seize the throne, York was killed at the Battle of Wakefield, and his son Edward inherited his claim per the controversial Act of Accord. The Yorkists lost custody of Henry in 1461 after the Second Battle of St Albans, but defeated the Lancastrians at the Battle of Towton. The Yorkist Edward was formally crowned in June 1461.
