[Cronos]

The Celts were all over Europe and were a serious competitor to the Roman Empire. Ultimately the Empire dissolved and the Celts remained, so in a sense the Celts won.

Ha Ha HA! Unless you classify the Germans as Celts (which may be true as the Romans did so, calling them Germanii or authentic Celts. Anyway, the Roman slaughtered the Celts and the ones remaining were subsumed by Latin colonists. Even the Germans who came and conquered parts of the Roman empire became Roman in manner and language (the Franks in France or the Goths in Spain). In the end we derive our culture from Rome, the GErmans gave up their barbaric primitive culture to accept the culture and civilisation of Rome. Rome, the Empire, civilisation won.

There were no Romans--no such thing--everyone was local people.
