Henry VI of the House of Lancaster is driven out by Edward IV of York. His wife Margaret flees to the French court, where she tries to persuade Louis XI to take up arms against England. Edward, who makes the unequal Lady Grey his queen, is defeated and Henry is reinstated as king. Edward then flees from captivity. Together with his younger brother and Richard of Gloucester – later Richard III – he defeats Henry's army, whose only son is stabbed to death by Richard of Gloucester. Henry VI dies by the same hand. Margaret, his widow, curses the House of York.
