<p>About empty thrones a lot can be said. Throughout history both ancient and near modern a lack of an heir and the sudden death of a beloved monarch always meant trouble. When the position of a king is up for grabs a lot of eager hands come forward. Pretenders and would-be heirs cousins and nephews bastard sons and daughters - they all came forward staking their claim to the throne. In the history of Medieval England such episodes were many. Usurpers who oust kings and heirs pretenders with long-forgotten dynastic claims: many once fought for the lucrative throne of the English Kingdom. However by far the most important of all these historic episodes lasted from 1455 to 1487 - 32 long years of struggle and bloodshed in England. And that episode was known as the&nbsp;Wars of the Roses.&nbsp;These wars ravaged England pitting two competing cadet families of the royal House of Plantagenet - York and Lancaster. Their supporters the Lancastrians and Yorkists descended into bitter warfare over the throne. For their symbols they took red and white roses respectively - thus giving the name to the conflict.</p>
