Answer: Clovis
Step-by-step explanation:
Clovis was the first king of the Franks to unite all of the Frankish tribes under one ruler, changing the form of leadership from a group of royal chieftains to rule by a single king and ensuring that the kingship was passed down to his heirs.
He is considered to have been the founder of the Merovingian dynasty, which ruled the Frankish kingdom for the next two centuries.
