Merovingian dynasty

The frequent wars had weakened royal power, while the aristocracy had made great gains and procured enormous concessions from the kings in return for their support. These concessions saw the very considerable power of the king parcelled out and retained by leading comites and duces (counts and dukes). Very little is in fact known about the course of the seventh century due to a scarcity of sources, but Merovingians remained in power until the eighth century.

Clotaire's son Dagobert I (died 639), who had sent troops to Spain and pagan Slavic territories in the east, is commonly seen as the last powerful Merovingian King. Later kings are known as rois fainéants ("do-nothing kings"), despite the fact that only the last two kings did nothing. The kings, even strong-willed men like Dagobert II and Chilperic II, were not the main agents of political conflicts, leaving this role to their mayors of the palace, who increasingly substituted their own interest for their king's. Many kings came to the throne at a young age and died in the prime of life, weakening royal power further.
