There is little reliable information about Marcus Claudius Tacitus. It does appear that after the murder of Aurelian, the soldiers of the Illyrian army, wishing to dissociate themselves from the assassins, sent a request to Rome that the Senate should nominate the new ruler, and pledged themselves to support their choice. After some delay, the Senate selected Tacitus, an elderly Senator who claimed descent from the great historian by the same name. Tacitus was thereby proclaimed Augustus.
Tacitus was seventy-five years of age at the time he assumed the throne. The new ruler soon joined the army in Thrace with Florianus at his side. Together they succeeded in repelling a Gothic invasion of Asia Minor. For this great victory, Tacitus took the title “Gothicus Maximus.” On his way back, he was going to face other barbarians by the Frankish and Alamannic invasion of Gaul, according to Historia Augusta. Tacitus died of fever at Tyana in Cappadocia in June 276 as his exertions of this campaign and the inclement climate proved too much for the aged Emperor. The historian Zosimus claimed Tacitus was assassinated, after appointing one of his relatives to an important command in Syria.
