Aurelian set out for another campaign against the Sassanids

The deaths of the Sassanid Kings Shapur I (272) and Hormizd I (273) in quick succession, and the rise to power of a weakened ruler (Bahram I), presented an opportunity to attack the Sassanid Empire, and in 275 Aurelian set out for another campaign against the Sassanids. On his way, he suppressed a revolt in Gaul—possibly against Faustinus, an officer or usurper of Tetricus—and defeated barbarian marauders in Vindelicia (Germany).
