There was a last Roman emperor, Romulus Augustus, who ruled the empire for less than a year before being deposed and sent into exile by Odoacer, who was some kind of barbarian, we don't know for sure. Ostrogoth, Han, Visigoth, Vandals, they all look the same to the Romans. Rome had been sacked by barbarians before, most notably by Olaric the Visigoth in 410. Is it Olaric or Olaric? The dictionary says Olaric, but the vampire diaries say Olaric, so I'm going to go with Olaric. But anyway, after 476 CE, there was never again a Roman emperor in Rome. Then there's the hipper, anti-imperialistic argument.
