The Germans did not destroy the world’s greatest civilization.
The Germanic tribes have been blamed for the collapse of the Roman Empire; however this is incorrect. For the most part the collapse of the Roman empire was not a collapse of an empire, but the slow integration of Germanic custom with Roman culture. This means the collapse of the Roman empire was a transfer of power from one ruling party to another. This transfer was neither peaceful nor quick, but it is the foundation of modern western society and Europe as we know it today.
