Who served as the first holy Roman Emperor from to 814?

Answer 1

charlemagne...

Answer 2

Charlemagne was crowned emperor by Pope Leo III in 800.

But Charlemagne was not crowned as Holy Roman Emperor. Instead he was crowned as Emperor of the Romans. There was much controversy about this because at that time there was a country in the East called the Roman Empire , and the implication was that the pope was making Charlemagne its emperor.

Today, historians call the medieval Roman Empire the Byzantine Empire, a term that was not used during the Middle Ages, to avoid confusing it with the ancient Roman Empire, though the Byzantine Empire was legally a continuation of the Roman Empire.

Charlemagne's empire, which the Franks called the Roman Empire briefly, is now called the Carolingian Empire.

The Carolingian Empire broke up; it was retained, as a legal entity, though it did not function for several decades. Historians now regard Otto I as the first Holy Roman Emperor, though no one seems to have called the empire by that name until the middle of the 12th century.
