Francia (Kingdom of the Franks) / King Carloman I

Carloman I, also Karlmann was king of the Franks from 768 until his death in 771. He was the second surviving son of Pepin the Short and Bertrada of Laon and was a younger brother of Charlemagne. Little is known of him, except such as touches upon his more famous father and brother. Carloman is mainly regarded by historians as Charlemagne's first steps towards acquiring the Holy Roman Empire, as his death allowed Charlemagne to take all of Francia and begin his expansion into other kingdoms.
