Normandy was disjointed from Norman rulers.
=== Celtic period ===Celts (also known as Belgae and Gauls) have populated Normandy since at least the Bronze Age
 While very little archeological excavations about the Vikings were done in Normandy, the Norman toponymy retains a large Scandinavian and Anglo-Scandinavian heritage, due to a constant use of Old Norse during four or five generations in certain parts of Normandy
