Political map of the Eastern Mediterranean on 11 Nov 308 (Diocletian and the Tetrarchy: Council of Carnuntum), showing the following events: Exile of Maximian; Domitius Alexander; Council of Carnuntum.

Maximian and Maxentius soon had a falling out and in April 308 Maximian took refuge with Constantine, encouraging Domitius Alexander in Africa to also break with Maxentius. That year Diocletian came out of retirement and, at Carnuntum in November, met with Galerius and Maximian in an attempt to restore stability to the empire. They agreed to appoint Licinius as a new Augustus, to confirm Constantine and Maximinus Daza as Caesars, and for Maximian to step down. For a moment an unprecedented eight emperors ruled the Roman world, but even after Diocletian and Maximian returned to retirement, a still daunting six remained.

Main Events

Apr 308 Exile of Maximian ▲

In a public gathering in Rome in April 308, Maximian, angered by the execution of Severus, blamed his son Maxentius for the troubles they faced and attempted to relieve him of the rank of Augustus. The crowd and the army immediately sided with Maxentius, forcing Maximian to flee to Gaul and the court of his son-in-law Constantine. in wikipedia

308 Domitius Alexander ▲

Following the exile of Maximian, Maxentius sent his own image to Carthage to demonstrate that he was now sole Augustus, but was rebuffed by the African legions, who had great respect for Maximian. When an angered Maxentius tried further measures to assert his authority in the region, the African legions revolted and proclaimed their vicarius Domitius Alexander as Augustus. Alexander—an elderly man who may have earlier served as Maximian’s praetorian prefect—quickly gained support across Africa and as far as Sardinia. in wikipedia

11 Nov 308 Council of Carnuntum ▲

In 308 Diocletian emerged from retirement to support Galerius and together the two met with Maximian at Carnuntum in November. Under the watch of Diocletian and Maximian, Galerius promoted his officer Licinius to become the new western Augustus, and confirmed Maximinus Daza and Constantine as Caesars. With the empire thus ‘stabilized’, Diocletian returned to his palace and cabbages at Salonae, while Maximian retired to Gaul. in wikipedia
