Crisis of the Third Century: An economic crisis strikes the Roman empire; due to the partition of the empire, invasions and usurpations and the sacking of the countryside and cities by invaders, agricultural and industrial production are significantly decreased, and mines lie unused. A monetary crisis ensues, including inflation of up to 1,000 % in certain areas of the empire.
Battle of Pavia: The Roman army pursues the Alamanni in Lombardy. Aurelian closes the passes in the Alps and encircles the invaders near Pavia. The Alamanni are destroyed and Aurelian receives the title Germanicus Maximus.
Felicissimus, financial minister of the state treasury, leads an uprising of mint workers against Aurelian. He is defeated and killed on the Caelian Hill.
Emperor Aurelian prepares a campaign against the Sassanids in Asia Minor. In Thrace, while waiting to cross the Bosphorus with his army, he hands out severe punishments to corrupt soldiers, and his secretary forges a list of high-ranking officers marked for execution.
