Charlemagne is the name of the king of the Franks and the first emperor of the Holy Roman Empire. His name is the French form of Latin Carolus Magnus, or Charles le Magne (Charles the Great). Charles comes from Old High German Karl meaning “man” via Proto-Germanic *karlaz (free man), of uncertain etymology but likely derived from a PIE origin. It was originally used to refer to men who were not thralls or or servants but who still lived at the bottom of society, connoting the idea of a “free man”. Magnus comes from a Latin word meaning “great; large, big”.
