General Constantius Chlorus defeated the Salian Franks for the Roman Empire in the Rhine delta in 288, and also reclaimed land south of the Rhine. He was appointed by emperor Maximian who was Roman emperor in the west. Diocletian was was the senior, and emperor of the east. The main target of Maximian was emperor Carausius of Roman Britain, of whom the Franks were allies. While Maximian was campaigning against Carausius and the Franks, Diocletian was ousting the Sarmatians from Pannonia.
In 289, Diocletian concluded his campaign against the Sarmatians and went east to try to convince the Arab tribes in the Arabian desert to ally and become vassals with the Romans instead of the Persians. Maximian in the meanwhile tried to reconquer north-western Gaul from Carausius. The governor of Mauretania Caesariensis campaigned against the rebellious Berber Bavares and Quinquegentiani in the Atlas Mountains.
