Gallia Lugdunensis
In March 68, Gaius Julius Vindex, the governor of Gallia Lugdunensis, rebelled against Nero's tax policies. Lucius Verginius Rufus, the governor of Germania Superior, was ordered to put down Vindex's rebellion. In an attempt to gain support from outside his own province, Vindex called upon Servius Sulpicius Galba, the governor of Hispania Tarraconensis, to join the rebellion and to declare himself emperor in opposition to Nero.
