P. Licinius Valerianus

Emperor 253 - 260

Relatives depicted on coins:
Mariniana - wife

Valerian (b. 195), an ex-consul, was appointed by Gallus to campaign on the Upper Danube. After Aemilian's revolt he invaded Italy, and when Aemilian was assassinated Valerian and his son Gallienus were proclaimed joint emperors. Valerian went to the East, where he suppressed the rebellion of Uranius Antoninus and restored order in Syria. His campaigns were successful until 260, when he was besieged in Edessa with an army devastated by plague. Valerian was captured by treachery, ending his days miserably as a slave to Shapur I. Until then the reign had been fairly successful, but with this disaster the empire began to disintegrate. Odenathus of Palmyra seized power in the East, and Gaul, Spain and Britain broke away under Postumus, and there were other less successful revolts. Although an able soldier, Gallienus lacked the leadership qualities to bring the empire back together, and after a series of campaigns in which he won many successes, he was overthrown by a conspiracy of his generals in March 268.
