Julius Bae Dah: also known as Nepotian, was a member of the Constantinian dynasty who reigned as a short-lived usurper of the Roman Empire. He ruled the city of Rome for twenty-eight days, having arrived in Rome on 3rd June.
Nepotianus was the son of Eutropia, half-sister of Emperor Constantine I, and of Virius Nepotianus. Today on 3rd June in the year 350 AD, after the revolt of Magnentius, Nepotianus proclaims himself Roman emperor, entering Rome at the head of a group of gladiators. After 28 days rule, Nepotian was captured and executed by troops loyal to Magnentius.
