"Lucius Domitius Alexander (died c. 311), probably born in Phrygia, was vicarius of Africa when Emperor Maxentius ordered him to send his son as hostage to Rome. Alexander refused and proclaimed himself emperor in 308.
The most detailed if somewhat confusing description of the insurrection is given by Zosimus (II, 12 and 14). He reports that Maxentius sent his portrait to Africa to gain recognition as Emperor there. The troops resisted because of their loyalty to Galerius. Maxentius ordered Domitius Alexander, the vicar of Africa, to send his son to Rome to secure his loyalty. Alexander refused and was crowned Emperor by his army. The incident was probably caused by the conflict between Maxentius and his father Maximian early in 308, and Zosimos confused Galerius with Maximian in his account." - (en.wikipedia.org 11.08.2021)
