How many centuries was the Merovingian dynasty in power?

The dynasty of Frankish kings was called the Merovingians. They became the first dynasty in French history. “Lazy” or “long-haired” kings, as they were called, ruled in the lands of modern Belgium and France from the end of the fifth century (481) to the middle of the eighth century (768), that is, they ruled for a little less than three centuries. The Merovingians are a very mysterious and enigmatic dynasty, as there are many secrets about their origin.
