Wars of the Roses
The Wars of the Roses 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. The wars extinguished the male lines of the two dynasties, leading to the Tudor family inheriting the Lancastrian claim. Following the war, the Houses of Tudor and York were united, creating a new royal dynasty, thereby resolving the rival claims.
