Effectively the last king of the Merovingian lineage, Dagobert II was murdered, along with (claims history) his son, by his seneschal, who went on to found the Carolingian dynasty which later ruled the Holy Roman Empire from Charlemagne on. Some people today still claim descent from Dagobert, and there are several conspiracies, most notably the Priory of Sion, rumoured to be plotting the return of these people to the throne of alternatively France, Europe or the world. Dagobert is claimed by some to have lived in the city of Rhedae, which today is called Rennes-le-Chateau, and has a history of its own.
