After their experiences with the predatory Roman governor and Lucius Apronius, the Frisii became disaffected towards Rome. In AD 47, a certain Gannascus of the Canninefates led the Frisii and the Chauci to rebel. They raided along the then-wealthy coast of Gallia Belgica. The Roman military commander, Corbulo, campaigned successfully against the Germanic tribes, For the Chauci and for the Frisii this meant Roman occupation, with the Romans specifying where they must live, with a fort built among them, and forcing a Roman-style senate, magistrates, and constitution upon them.
