Operating with faulty intelligence and desperate to defeat the Goths on his own, Valens forced the disasterous Battle of Adrianople in August 378.

In 375 the Huns exploded into Gothic territory, sending refugees fleeing for the saftey of the Roman Empire.

Valens spent the late 360s and early 370s dealing with hostile Goths in the north and hostile Persians in the east. In 375 he would be left to face these threats alone when Valentinian suddenly died.

in the late 360s and early 370s AD Roman mismanagment of three different regions in the Western Empire led to armed conflict.

In the winter of 367 Britannia was hit from all sides by a coordinated barbarian invasion. It would be more than a year before the Romans were able to reassert control over the island.

Shortly after Valentinian and Valens ascended to the throne, one of Julian the Apostate's maternal cousins seized control of Constantinople.

Jovian extracted the Roman legions from the east at a heavy price. He then ruled the Empire for eight months before suddenly dying on his way to Constantinople in early 364.

In 363 Julian launched an invasion of Sassanid Persia. He would die in battle just three months later.

Julian came to power in late 361 and immediately set about trying to turn back the clock on both Church and State.

Once he was established as a force to be reckoned with in the west, Julian revolted against Constantius II in 360 after the Emperor ordered half the Gallic army redeployed to the eastern frontier.
