Macrianus the younger was one of the 30 usurper emperors written about in the Historia Augusta. He was appointed in 260 CE along with his father Titus Fulvius Macrianus in response to the disastrous defeat and capture of Valerian by King Shapur. Macrianus the elder would only accept the emperorship upon the condition that his sons, Fulvius Julius Macrianus and Fulvius Julius Quietus, share the position. Macrianus and his sons then drove the Persians out of Antioch, where they would establish the center of their power in the East. Soon they gained control of Egypt but were killed in Ilyricum in 261 CE by Aureolus and Domitianus, generals of Gallienus. Andrew Carroll 2011.
