Valentinian II - Augustus of Imperium Romanum from 375 to 392
Flavius Valentinianus Augustus was Roman Emperor from AD 375 to 392.

Valentinian himself seems to have exercised no real authority, and was a figurehead for various powerful interests: his mother, his co-emperors, and powerful generals.

He was thoroughly dominated by the Frankish general Arbogast. When Valentinian formally dismissed Arbogast, the latter ignored the order, publicly tearing it up and arguing that Valentinian had not appointed him in the first place.

On 15 May 392, Valentinian was found hanged in his residence in Vienne. Arbogast maintained that the emperor’s death was suicide. Unlikely.
