The historical significance of the War of the Roses in England lies in its impact on the monarchy and the establishment of the Tudor dynasty. This series of civil wars from 1455 to 1487 was fought between the rival houses of Lancaster and York, both vying for the English throne. The conflict resulted in significant political instability and the weakening of noble power, ultimately leading to the rise of Henry Tudor (Henry VII) after the decisive Battle of Bosworth in 1485. The Tudor dynasty, characterized by strong centralized rule, laid the groundwork for the modern English state and significant developments in English history, including the Reformation.
