A series of civil wars and repeated invasions by Germanic tribes caused the collapse of the Western Roman Empire. Following the end of imperial authority, several Germanic tribes struggled against each other for control of territory. The Franks became the dominant power in Gaul, but Greater Frankia repeatedly broke apart during wars between rival claimants for the throne. Finally, Charlemagne united the Franks, and greatly expanded the size of the kingdom. However, his grandsons proved unwilling to share the empire, and divided it in 843, laying the foundations for France and Germany. Episode Thirty-four explains that Charles' son, Louis, took advantage of domestic instability in the emirate of Cordoba to expand south of the Pyrenees. Charles then had to deal with a coup in Rome when the relatives of the previous pope attempted to capture Leo, the current pope. The two men clearly came to an agreement since Leo crowned Charles emperor. Honestly, the elevation in status should not have been a surprise since Charles had advanced beyond the status of a mere king by this time. Moreover, the eastern empire was ruled by empress Irene, who had seized power from her weak son.
