--------------------------------------------------
Marcus Annius Florianus Augustus was Roman Emperor for a few months in 276. Florian was reportedly a maternal half-brother to the Emperor Marcus Claudius Tacitus. Appointed Praetorian Prefect in Tacitus's army in his campaign against the Goths, according to the available sources, he was chosen by the army in the West to succeed Tacitus in 276, without the Roman Senate consensus. However he minted coins bearing the "SC" legend, thus showing some bonds to the Senate.

He was fighting against the Heruli when the army in the East elected Probus. Probus had the support of Italia, Gaul, Hispania, Britain, Africa, and Mauretania. The two rival emperors met in battle in Cilicia. Florianus had the larger army, but Probus was a more experienced general, and avoided a direct clash. Florian's western army was unused to the dry and hot eastern climate and Probus likely secured a small victory. Florian was assassinated by his own troops near Tarsus once their confidence was lost. Florianus died in September 276, having been emperor for only eighty-eight days.
