Plantagenet, Lancaster and York Family Tree
William the Conqueror. England's Hitler. He kept himself on the throne by using the art of terror. When some northerners rose up against him he caused citizens to be slaughtered and the lands to be destroyed, reducing the population of the north of England by 50 per cent. I have not heard of such atrocities by any other English ruler against the citizens of England itself.
