The Roman legions in Germania Superior refuse to swear loyalty to Galba. They rebel and proclaim Vitellius as emperor.
Roman legions in Germania Superior rebelled against Emperor Galba and proclaimed Vitellius as emperor, igniting a civil war.
After Emperor Nero's death in 68 AD, Galba assumed the throne but faced widespread distrust among military ranks. On January 2, 69 AD, the legions of Germania Superior refused to swear loyalty to Galba and instead acclaimed their governor, Aulus Vitellius, as emperor. This defiance sparked the civil conflict known as the Year of the Four Emperors. Vitellius quickly secured the support of additional legions along the Rhine frontier. His forces prepared to march westward toward Rome to challenge Galba's rule. The rebellion marked the beginning of a tumultuous period of rapid imperial successions and battles for power.
