"The Germans living in southern Sweden and northern Germany moved south and pushed the Celts west. The Romans tried to control the Germans and were seriously beaten by them in AD 9. The Romans traded with some friendly German tribes, and recruited some into the Roman army. Some tribes such as the Franks, Alemanni and Goths raided the empire in 260-270 and the Romans had to make peace and settle them."
