Main Events

Jun–Sep 276 Principate of Florian

After the death of Tacitus, the army in Asia Minor chose his half-brother Florian to succeed him as emperor in June 276. Florian seems to have been quickly recognized by the Roman Senate, but was unable to achieve much—and most likely never returned to Rome—before Aurelian’s general Probus revolted in Syria. After just over two months’ rule, Florian was either killed by his own troops or forced to commit suicide by opening his veins.in wikipedia

Jun 276 Probus’ Revolt

When the eastern legions learned of the death of Tacitus and his succession by Florian in June 276, they proclaimed Marcus Aurelius Probus—their general and a veteran of Aurelian’s restoration wars—as emperor. Probus quickly gained recognition in Syria, Phoenice, Palestina, and Egypt, but lacked both the troop numbers and wider support of his rival Florian.in wikipedia

Aug–Sep 276 Probus–Florian War

When Florian heard of Probus’ claim, he abandoned his pursuit of the Heruli—allowing these invaders to escape across the Black Sea—and headed south to Tarsus with his army. Outnumbered by his rival, Probus avoided direct combat until Florian’s troops—who were mostly European and therefore unaccustomed to the climate of Cilicia—began suffering from the summer heat and disease. Probus then attacked and easily defeating his weakened enemy outside Tarsus, deposing Florian.in wikipedia
