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.
