Medieval Warfare focusses on the Wars of the Roses.
In the mid-fifteenth century, the ruling king of England, Henry VI, suffered from bouts of insanity. Because of this, Richard Duke of York ruled in his stead as 'Protector of the Realm'. During a brief recovery, Henry replaced Richard with his own favourites. Richard and his ally, the Earl of Warwick, feared for their safety and so gathered their armies. The Wars of the Roses had begun.
