By 69, however, Civilis, the Batavi regiments and the Batavi people had become utterly disaffected from Rome. After the Batavi regiments were withdrawn from Britain in 66, Civilis and his brother (also a prefect) were arrested by the governor of Germania Inferior on false accusations of treason. The governor ordered the brother's execution, and sent Civilis to Rome in chains for judgement by the Roman emperor Nero. (The difference in treatment indicates that the brother was still a "peregrinus" i.e. a non-citizen subject of the empire, while Civilis, as his name implies, had been accorded Roman citizenship, which entitled him to have his case heard by the emperor in person). While Civilis was in prison awaiting trial, Nero was overthrown in AD 68 by an army led into Italy by the governor of Hispania Tarraconensis, the veteran general Servius Sulpicius Galba. Nero committed suicide, ending the rule of the Julio-Claudian dynasty, founded a century earlier by Augustus. Galba was proclaimed emperor. He acquitted Civilis of the treason charge and allowed him to return home.
