William was Duke of Normandy and yes Normandy was technically part of France. But to tell the truth, the King of France had no real power and Normandy was actually independant. So were big feudal powers like Burgundy, Aquitaine or Bretagne. About Richard Lionheart: He almost never visited England because he was actually Count of Anjou, Duke of Normandy and Duke of Aquitaine. Those french lands were much more populated and much richer than that oversea kingdom his ancestor William conquered 80 years earlier. So if you really want to make him a civ leader, he should rather be France.
