Charlemagne also known as Charles the Great or Charles I, was the first emperor in western Europe since the collapse of the Western Roman Empire 3 centuries earlier. Called the Father of Europe, He united most of Western Europe.
Famously, Charlemagne was crowned Emperor of the Roman People on December 25, 800 by Pope Leo III. After that the subsequent emperors of the Carolingian and Holy Roman Empires were generally, but not all, crowned by the pope. When a person was elected emperor, he was not called the emperor, but King of Germany until the pope crowned him, but sometimes this took years to happen.
Charlemagne was crowned as emperor on the Romans in 800 by pope Leo III. He was given the title of emperor of the Romans to signify the independence of Latin Christian (Catholic) western Europe form the eastern Roman (also called Byzantine by historians) Emperor and the Greek Christian (Orthodox) east. He ruled over what historians have called the Carolingian Empire which covered much of continental Western Europe.
In 800, Pope Leo III (750-816) crowned Charlemagne emperor of the Romans.
Between the coronation of Clovis in 496 and the eighth century, the Franks expanded their territory through much of Western Europe. Charlemagne was crowned Holy Roman Emperor in 800.
