Answer: England
Step-by-step explanation:
The War of the Roses which was fought sporadically between 1455 and 1487 were a series of conflicts betwen the House of York and the House of Lancaster with the main bone of contention being the highest price of the Throne of England.
Even though the House of York was initially victorious, the wars decimated both houses until an eventual victory for the House of Tudor which had inherited the claim of the House of Lancaster.
