How did the War of the Roses effect Parliament?

The War of the Roses, a series of civil wars in England from 1455 to 1487, significantly affected Parliament by highlighting its role in legitimizing power and governance. The conflict weakened the authority of the monarchy and led to increased political instability, prompting a greater reliance on Parliament for support and legitimacy. Additionally, the struggle between the houses of Lancaster and York contributed to the evolution of political factions within Parliament, setting the stage for a more structured parliamentary system in subsequent years. Ultimately, the war laid the groundwork for the rise of the Tudor dynasty, which sought to strengthen parliamentary governance.
