Political map of Europe & the Mediterranean 7 June 68 AD (Downfall of Nero): Nero’s extravagances alienated the Roman elite, encouraging the governors Vindex (Gaius Julius Vindex) and Galba to lead the Gallic and Spanish provinces in revolt in 68 AD. Although Vindex was quickly defeated by the Rhine legions, the Praetorians (Praetorian Guard) and Senate (Roman Senate) declared for Galba in June. Deposed and condemned, Nero committed suicide, bringing an abrupt end to the Julio-Claudian dynasty.
