The German Campaign Against the Romans

When the war with Parthia erupted, the Romans were forced to redeploy the legions to meet the threat. This meant that while the east was reinforced, the Rhine and Danube frontiers were depleted. Governors were forced to rely on locally raised militias rather than proper legions in maintaining peace along the border. It did not take long for the Germans to notice the shift. With Roman attention diverted east, this might prove the perfect opportunity for the Germans of Pannonia to press for greater concessions.
