Charlemagne
Charlemagne or Charles the Great, a member of the Carolingian Dynasty, was King of the Franks from 768, King of the Lombards from 774, and the first Holy Roman Emperor from 800. Charlemagne succeeded in uniting the majority of western and central Europe and was the first recognized emperor to rule from western Europe since the fall of the Western Roman Empire around three centuries earlier. The expanded Frankish state that Charlemagne founded was known as the Carolingian Empire. He was later canonized by Antipope Paschal III— later treated as invalid—and he is now regarded as beatified by the mainstream Catholic Church. Charlemagne was the eldest son of Pepin the Short and Bertrada of Laon. He was born before their canonical marriage. He became king of the Franks in 768 following his father's death, and was initially as co-ruler with his brother Carloman I until the latter's death in 771.
