The great scholar king of frank was

Charlemagne (c. 742-814), also known as Karl and Charles the Great, was a medieval emperor who ruled much of Western Europe from 768 to 814. In 771, Charlemagne became king of the Franks, a Germanic tribe in present-day Belgium, France, Luxembourg, the Netherlands and western Germany. Charlemagne was born around 742, the son of Bertrada of Laon and Pepin the Short, who became king of the Franks in 751. Charlemagne’s exact birthplace is unknown, although historians have suggested Liege in present-day Belgium and Aachen in modern-day Germany as possible locations. Similarly, little is known about the future ruler’s childhood and education, although as an adult, he displayed a talent for languages and could speak Latin and understand Greek, among other languages.
