In honor of the Ides of March, a poll....
Who was the actual Last Roman Emperor?
Romulus August (The "Intro the History" answer)
Julius Nepos (The "I've read up on the Roman Empire" answer)
Constantine VI (The "I'm being clever" answer)
Constantine XI Palaiologos (The correct answer)
Francis II, Holy Roman Emperor (The "I'm looking for an argument" answer)
Mehmed VI/Nicholas II/Wilhelm II/other (The "I want a LOUDER argument" answer)
Romulus Augustus is, as I noted, the answer you're often given in basic history courses. The uncontested last de facto emperor of the Western Roman Empire, he was the last emperor whose administration had even a semblance of authority in the western territories. I say his "administration" instead of himself because he was a child during his one year of rule and his father, Orestes, had actual control. But his father gave him the title, and for about a year the title had meaning (Not a lot, but some). After he was deposed by Odoacer in 476, nobody else within the western lands had any authority except Odoacer and the other new states that were springing up.
Julius Nepos was the last de jure emperor in the west. He actually ruled before Romulus Augustus, until Orestes deposed him and put his son on the throne. But despite being deposed he lived, and for several years after the overthrow of Romulus Augustus he was offered symbolic obeisance by the people who had actual power. Odoacer, who at this point was 'King of Italy', claimed that Julius Nepos still ruled as emperor, and even minted coins using his image. Zeno, who was emperor in the Eastern Roman Empire, likewise recognized Julius Nepos as the emperor in the west. It wasn't until his death in 480 that Zeno formally dissolved the position of emperor in the west and claimed sole rulership of the entire empire.
Constantine VI gets on this poll mainly as a point of technicality, but technicalities often have merit. He is the last person who was universally acknowledged as the Roman Emperor. Both in the Eastern Roman Empire (Generally called the Byzantine Empire at this point) which he ruled directly, and also the polities in western Europe that were independent in practice but acknowledged the authority of the Roman Empire. After he was deposed by his mother Irene in 797 she successfully seized the throne for herself in the east, but the western states refused to acknowledge her authority. They declared that the position of Roman Emperor was vacant, and Pope Leo III declared a new emperor (Charlemagne, from which the later Holy Roman Emperors claimed descending authority).
Constantine XI Palaiologos was the last ruler of the Eastern Roman Empire (Byzantine Empire), which had directly continued the institutions, law, and culture of the Roman Empire despite the collapse of its territories in the west. He died during the conquest of Constantinople itself in 1453, after which there was no remaining Roman Empire for anybody to claim authority over.
Francis II wasn't the last Roman Emperor, don't be a dick. We don't truck with the translatio imperii in this day and age.
Mehmed VI/Nicholas II/Wilhelm II/other weren't the last Roman Emperors, either. I SAID don't be a dick.
