Map of Charlemagne's empire, 768-843. Charlemagne, a.k.a Charles the Great or Charles I, was king of the Franks from 768, king of the Lombards from 774, and was crowned emperor in 800. Charlemagne died in 814 and was succeeded by his only surviving son, Louis I. Louis's death in 840 was followed by civil war between his three sons, which resulted in the split (and the end) of the empire in three parts in 843.
