Charlemagne ( /ˈʃɑrlɨmeɪn/; ; c. 742 – January 28, 814 at Aachen), also known as Charles the Great (Latin: Carolus Magnus or Karolus Magnus; German: Karl der Grosse) or Charles I, was the founder of the Carolingian Empire, reigning from 768 until his death. He expanded the Frankish kingdom, adding Italy, subduing the Saxons and Bavarians, and pushed his frontier into Spain. The oldest son of Pepin the Short and Bertrada of Laon, Charlemagne was the first Emperor in Western Europe since the fall of the Roman Empire three centuries earlier.
Becoming King of the Franks in 768 following the death of his father, Charlemagne was initially co-ruler with his brother Carloman I. Carloman I's sudden death in 771 under unexplained circumstances left Charlemagne as the undisputed ruler of the Frankish Kingdom. Through his military conquests, he expanded his kingdom into an empire that incorporated much of Western and Central Europe.
Charlemagne continued his father's policy towards the papacy and became its protector, removing the Lombards from power in Italy, and leading an incursion into Muslim Spain. He also campaigned against the peoples to his east, forcibly Christianizing them along the way (especially the Saxons), eventually subjecting them to his rule after a protracted war. Charlemagne reached the height of his power in 800 when he was crowned as "Emperor" by Pope Leo III on Christmas Day.
Called the "Father of Europe" (pater Europae), Charlemagne's empire united most of Western Europe for the first time since the Roman Empire. His rule spurred the Carolingian Renaissance, a revival of art, religion, and culture through the medium of the Catholic Church. Through his foreign conquests and internal reforms, Charlemagne encouraged the formation of a common European identity. Both the French and German monarchies considered their kingdoms to be descendants of Charlemagne's empire.
Charlemagne died in 814 after having ruled as Emperor for just over thirteen years. He was laid to rest in his imperial capital of Aachen. His son Louis the Pious succeeded him as Emperor.
