Gallic Empire
In 260 CE, as the Roman Imperial Crisis of the Third Century reached its climax, Postumus, a Germanic soldier in Roman service, established the Gallic Empire, which claimed suzerainty over Germania, Gaul, Hispania and Britannia. Postumus was eventually assassinated by his own followers, after which the Gallic Empire quickly disintegrated. The traditional types of border battles with "Germani", Sarmatians and Goths continued on the Rhine and Danube frontiers after this.
