The crisis began in March 235, when Severus Alexander was murdered by his own troops near Mogontiacum (Mainz). Over the next fifty years more than fifty men claimed the title of emperor, about half of them with some claim to legitimacy, and most died violently. Goths and other peoples raided the Balkans and Asia Minor, Franks and Alamanni crossed the Rhine, and in 260 the Persian king Shapur I captured the emperor Valerian. The West broke away as the Gallic Empire (260–274), the East came under Palmyra, the Plague of Cyprian (249–262) ravaged the cities, and the debased silver coinage became almost worthless.

Soldier-emperors from the Danubian provinces — Claudius II, Aurelian, Probus — turned the tide. Aurelian reunited the empire in 272–274, and Diocletian, proclaimed at Nicomedia on 20 November 284, rebuilt the state on new foundations. Historians date the end of the crisis to 284 or to his final victory over Carinus in 285.
