Gallia Lugdunensis
In order to secure his position as Roman Emperor, Vespasian, along with his allies Antonius Primus and Mucianus, decided to stir up trouble in Germany so as to distract Vitellius, the current Roman Emperor. A letter was sent to a Batavian chieftain, Julius Civilis, encouraging him to start a rebellion. Liking the idea, Civilis revolted and began to harry Gallia Lugdunensis.
