I can see that you can copy lines (and lies) from a German wikipedia, written by German "historians" who just wanted to prove their "superiority". In fact Goths was a Roman term for all tribes north of the Roman empire. And the reason why the divided them into two groups Visigoths and Ostrogoths was obvious: they spoke completely different languages, Ostrogoths speaking Slavic language. Thats why all the kings and leaders of Ostrogoths and Vandals had purely Slavic names. Ostrogoth lived between Poland and serbia, in the Danube basin, east of the amber-routes inhabited by and controlled by the Veneti slavs. Check the facts and dont just copy German encyclopedias.
