The main conflict of the War of the Roses in England stemmed from power struggles between two rival factions: the House of Lancaster and the House of York. Both families sought control of the English throne during the 15th century, and this dynastic conflict was ignited by issues of legitimacy, governance, and royal succession. The Wars were marked by a series of battles, intrigue, and changing allegiances, ultimately leading to the rise of the Tudor dynasty after Henry Tudor (Henry VII) defeated Richard III at the Battle of Bosworth Field in 1485. The conflict transformed England’s political landscape and ended decades of civil strife.
