The successor, Gallus, treated with the Goths, allowed them to keep their booty, and embarrassed the Senate with his barbarian concessions, but the Goths broke that treaty and began to harass the borders once again. The Roman general in the area, Aemilius Aemilianus, pushed them back and was rewarded with the proclamation of emperor by his troops. He rushed to Rome, and killed Gallus but was assassinated himself 88 days later. It was 253 A.D.
Aemilianus’ successor, Valerian, spent his reign fighting in Syria, only to be captured and die in prison circa 260 A.D. His son, Gallienus, tasked with fighting along the Danube frontier, defeated the Juthungi tribe 259 A.D. at Milan after they crossed into Italy intent on attacking Rome.
