Lucius Domitius Alexander, the vicarius of Africa, was proclaimed emperor by his troops around 308 AD — likely under pressure rather than genuine ambition — and held control of the critical North African grain supply long enough to strangle Rome's provisioning for roughly three years. Maxentius, who controlled Italy and needed that grain, sent his praetorian prefect Rufius Volusianus with an army that crushed Alexander's forces in 310 or 311. Alexander was captured and strangled.
The Carthage mint operated for the entirety of this brief usurpation and nowhere else, making it the sole source of Alexander's coinage.
