RIC VI Carthage 26a
This coin celebrates the defeat of the Quinquegentiani (People of the Five Tribes), who were a confederation of Berbers in North Africa. They were under Roman rule, but rebelled in A.D. 289 and were successful for a few years until Maximianus Herculius launched a series of devastating attacks starting in A.D. 297 and finishing in A.D. 298, after which, the Quinquegentiani were never heard of again.
