The outcome of the War of Roses in England during the 15th century was the ascension of the Tudor dynasty, specifically Henry VII, to the throne. This series of civil wars, which occurred between 1455 and 1487, was primarily fought between the rival houses of Lancaster and York over control of the English crown. The war ended decisively at the Battle of Bosworth Field in 1485, where Lancaster's Henry Tudor defeated the Yorkist King Richard III. Henry VII's victory marked the end of feudal conflicts, leading to a more centralized monarchy and significant changes in governance, heralding the start of the Tudor era.
