When King Richard II was overthrown in 1399, antagonism between the House of York and the House of Lancaster, both branches of the royal House of Plantagenet, began to emerge. Eventually the two houses fought for the throne of England in a series of civil wars, commonly known as the Wars of the Roses. Some of the battles took place in Yorkshire, such as those at Wakefield and Towton, the latter of which is known as the bloodiest battle ever fought on English soil.
