Charlemagne
The Franks—one of the Germanic peoples who had moved their homes over the River Rhine into the Roman Empire as it was falling apart—were, by the year 700, the rulers of Gaul, and a lot of Germania east of the Rhine. They also protected the Papacy and the Roman Catholic faith. When their king Pepin the Short died, his sons, Charlemagne and Carloman were chosen to share the kingdom. They divided it into two parts: one half for Charlemagne, and the other for Carloman. Carloman died on December 4, 771, leaving Charlemagne as the leader of the whole Frankish kingdom.
