Flavius Victor - Augustus (usurper) of Imperium Romanum from 384 AD to 388 AD
Flavius Victor Augustus was the son of Magnus Maximus. He was proclaimed an Augustus by his father and ruled nominally from 384 to his death in 388.

Originally considered a usurper, Maximus and Victor gained recognition of their legitimacy for their co-reign by Theodosius in 386. In 387, Maximus campaigned in Italy against Valentinian II. Victor was left behind in Trier. His father defeated Valentinian but failed against a then hostile Theodosius in 388. Theodosius sent Arbogastes to Trier to slay Victor.

Victor's death left Valentinian II, Theodosius and Arcadius as the sole Augusti in the Empire.
