The rise and fall of the Gauls and the Gallic empire was a rather interesting piece of European history. Native Celts in modern day France trying to fend off Roman invaders and eventually rebelling and attempting to form their own empire/nation only to fall in a matter of years and the Gauls eventually becoming another people integrated into the Roman, and eventually Romance, civilization. But I'm not talking about what will happen to Gaul/Gallic empire or the Romans if either lived on. I'm talking about what happens to the German barbarians that eventually brought an end to the Western Roman empire. If the region remains dominated by Celts, what would happen to the Germans? Would they still try to cross the Rhine and bring an end to both the Gauls and Romans? Would the Franks try to integrate Gaul into itself or remain in Germania? Would the Franks, along with the Visigoths and Lombards, even exist? Tell me what your thoughts about it are.
