Victor

Flavius Victor was co-emperor from 384-388 AD, after being declared Augustus by his father, Magnus Maximus.
In 386 AD, Theodosius recognised Magnus and Victor's legitimacy. But then, a year later, war broke out between the Augusti. While Magnus campaigned in Italy, Victory was in Trier. After his father was defeated, the general Arbogastes was sent to Trier and killed Victor.
