Gallienus

Also known as Publius Licinius Egnatius Gallienus

Publius Licinius Egnatius Gallienus (, ; – September 268) was Roman emperor with his father Valerian from 253 to 260 and alone from 260 to 268. He ruled during the Crisis of the Third Century that nearly caused the collapse of the empire. He won numerous military victories against usurpers and Germanic tribes, but was unable to prevent the secession of important provinces. His 15-year reign was the longest in half a century.

AI overview

Gallienus was a Roman emperor who ruled jointly with his father from 253 to 260 and then alone until his death in 268, making his 15-year reign the longest in fifty years. Though he won many battles against rival claimants and Germanic invaders during the empire's near-collapse in the third century, he could not stop major provinces from breaking away, leaving a fractured empire at the end of his rule.

Born into a wealthy and traditional senatorial family, Gallienus was the son of Valerian and Mariniana. Valerian became Emperor in September 253 and had the Roman Senate elevate Gallienus to the rank of Augustus. Valerian divided the empire between him and his son, with Valerian ruling the east and his son the west. Gallienus defeated the usurper Ingenuus in 258 and destroyed an Alemanni army at Mediolanum in 259.
