In the early Empire, the same Germanic tribes that had fought for Ariovistus appeared on both sides of the Rhine in Alsace. Then, they were of mixed ethnicity and perhaps no longer spoke Germanic. It seems clear that the Romans had allowed them to take the former lands of the now missing Boii, in exchange for serving as a buffer against the Suebi. They did serve long and faithfully. The province of Germania Superior was formed from them. As for the Germans who had already settled among the Celts, it is not clear what happened to them; however, there is no record of any ethnic cleansing. It is more likely that they integrated into the new Romano-Celtic population.
