Why did the adoption of Christianity by the Franks coincide with the folding of the Frankish state?

The adoption of Christianity by the Franks coincided with the creation of the state, because the ruler of the Frankish tribes Clovis sought to create a single state, and the monotheistic religion only contributed to the rallying of the people. Clovis baptized himself and baptized his people. He independently formed an empire in order to compete with other states and increase his own authority. The church supported the ruler, and Clovis, in turn, bestowed privileges, lands, privileges and other riches on the church.
