Edward was briefly deposed and fled to Flanders the following year, and Henry was reinstalled as king. In 1469, Warwick withdrew his support for Edward due to opposition against the king's foreign policy and choice of bride, and changed to the Lancastrian claim, leading to a renewal in fighting. Resistance to Edward's rule continued but was defeated in 1464, leading to a period of relative peace. The Yorkists lost custody of Henry the following year but destroyed the Lancastrian army, and Edward was crowned three months later in June 1461. Yorkists, led by Warwick the Kingmaker, recaptured Henry, but Richard was killed in 1460, leading to the claim by his son, Edward.
The wars began in 1455 when Richard of York captured King Henry VI in battle and was appointed Lord Protector by Parliament, leading to an uneasy peace. Historians disagree over which of these factors were the main catalyst for the wars.
The conflict had its roots in the wake of the Hundred Years' War and its emergent socio-economic troubles, which weakened the prestige of the English monarchy, unfolding structural problems of bastard feudalism and the powerful duchies created by Edward III, and the mental infirmity and weak rule of Henry VI, which revived interest in the Yorkist claim to the throne by Richard of York. Following the war, the Houses of Tudor and York were united, creating a new royal dynasty, thereby resolving the rival claims. The wars extinguished the male lines of the two dynasties, leading to the Tudor family inheriting the Lancastrian claim. The Wars of the Roses, known at the time and for more than a century after as the Civil Wars, were a series of civil wars fought over control of the English throne in the mid-to-late fifteenth century, fought between supporters of two rival cadet branches of the royal House of Plantagenet: Lancaster and York.
