Margaret

Widow of the dead King Henry VI and mother of the slain Prince Edward. In medieval times, when kings were deposed, their children were often killed to remove any threat from the royal line of descent—but their wives were left alive because they were considered harmless. Margaret was the wife of the king before Edward, the Lancastrian Henry VI, who was subsequently deposed and murdered (along with their children) by the family of King Edward IV and Richard. She is embittered and hates both Richard and the people he is trying to get rid of, all of whom were complicit in the destruction of the Lancasters.
