The War of Roses was fought over a dynastic conflict in England between two noble houses: the Lancasters, represented by a red rose, and the Yorks, symbolized by a white rose. The struggle for the English throne primarily occurred between 1455 and 1487, fueled by political power, territorial control, and competing claims to the crown. The conflict involved a series of battles, shifting alliances, and periods of interregnum. Ultimately, the war concluded with the rise of the Tudor dynasty when Henry Tudor (Henry VII) defeated Richard III at the Battle of Bosworth Field in 1485, significantly altering England's political landscape and monarchy.
