The Frisiavones were possibly clients of the Batavi, for whom they supplied auxiliary troops and contingents that came to be incorporated into Batavian units of the Roman army. This situation may have persisted until the Batavian revolt (69–70 AD). According to Nico Roymans, "after the Batavian revolt the Frisiavones and the Cananefates were given an opportunity to express their own identity."
