Firmus (4th-century usurper)
The misbehaviour of Romanus, who had neglected protection from African tribes to Roman cities that had refused the payment of bribes, had worsened the situation in Africa Province in the 360s.[4] Quickly obtaining support from the Berber tribes, including the Abanni and the Caprarienses,[5] he presented Theodosius with the prospect of a protracted guerilla war against the elusive barbarians of the Numidian desert, such as Rome had faced against Jugurtha and Tacfarinas in preceding centuries.Ultimately, Igmazen, king of the Isaflenses, was induced by fear or defeat to surrender Firmus to the Romans.[7] His body was transported, allegedly on the back of a camel, on Theodosius' return to Sitifi, as proof of the end of the revolt.Firmus ordered the killing of the Nicene inhabitants of Rusuccuru, and after his death, Valentinian issued laws against the Donatists.
