What Latin name is Charlemagne also known by?

Charlemagne is also known by the Latin name Carolus Magnus. The name means “Charles the Great”: Carolus is the Latin form of Charles, while magnus means “great.” His name entered many European languages through Latin scholarly, religious, and administrative writing.

Charlemagne was born around 742 and became king of the Franks in 768, ruling first with his brother Carloman and then alone after Carloman’s death in 771. Through conquest, diplomacy, and religious alliances, he expanded Frankish power across much of western and central Europe.

Pope Leo III crowned him emperor in Rome on Christmas Day 800. That imperial title helped shape the later idea of the Holy Roman Empire, although Charlemagne’s empire and the medieval empire that followed it were not identical institutions.

The alternative names in this question refer to other Carolingian figures or rulers. Pippinus Brevis means Pepin the Short, Charlemagne’s father; Ludovicus Pius was his son Louis the Pious; and Carolus Martellus was his grandfather Charles Martel. “Carolus Magnus” is the Latin form specifically associated with Charlemagne.
