The German tribes oln the border of the Roman Empire were "uncivilized". What if, for reasons of trade, commerce and better relations, the Germans decide to adopt Latin words, customs and beliefs over the coarse of ~3 centuries (assuming they don't invade the Romans).
The Germans adopted thousands of customs and weapons from the Romans, especially in ther military apect. Roman weapons can be found as far as Norway. Germans also tried to identify with the Roman nobility. German soldiers also served in the Roman army. Tradse also suggests, through archeological finds of Scandinavian amber in Greece before Roman times, that an already existing complex trade route existing in Europe. Hostilities only truely began when the Empire began to fall.
So, what are the effects of the Latinization of Germans? And what else would be needed for the Latinization of the Germans?
