title: Wars of the Roses
context: The Wars of the Roses were a series of English civil wars for control of the throne of England fought between supporters of two rival branches of the royal House of Plantagenet: the House of Lancaster, associated with a red rose, and the House of York, whose symbol was a white rose. Eventually, the wars eliminated the male lines of both families. The conflict lasted through many sporadic episodes between 1455 and 1487, but there was related fighting before and after this period between the parties. The power struggle ignited around social and financial troubles following the Hundred Years' War, unfolding the structural problems of feudalism, combined with the mental infirmity and weak rule of King Henry VI which revived interest in Richard of York's claim to the throne. Historians disagree on which of these factors to identify as the main reason for the wars.[5]
