The Question: Who did Pope Leo III crown “Emperor of the Romans” in 800 CE?
Constantine the Great
In medieval times, popes played a big role in determining the future of various Catholic kingdoms. Elected pope in 795 CE, Pope Leo III acquiesced to the growing power of Frankish King Charlemagne, a big departure from his predecessor, Adrian I, who tried to remain independent of the king’s growing empire. On Christmas Day, 800 CE, Leo III crowned Charlemagne “Emperor of the Romans,” over 400 years after the fall of the Western Roman Empire.
The correct answer is Charlemagne.
