Time: Sep, 253
Place: Spoletium, Italy, Roman Empire
Details: Valerian, governor of the Rhine provinces, was on his way south with an army which, according to Zosimus, had been called in as reinforcement by Gallus. But modern historians believe this army, possibly mobilized for an incumbent campaign in the East, moved only after Gallus' death to support Valerian's bid for power. Emperor Aemilian's men, fearful of civil war and Valerian's larger force, mutinied. They killed Aemilian at Spoletium or at the Sanguinarium bridge, between Oriculum and Narnia (halfway between Spoletium and Rome), and recognized Valerian as the new emperor.
