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

The formation of the Frankish state coincides with the period of their adoption of Christianity, because often the adoption of a monotheistic religion leads to the unification of peoples. Clovis decided to introduce Christianity into the Frankish tribes in order to create a single state. The faith that replaced paganism positively influenced the consciousness of the Frankish tribal unions. As a result of their rallying, the Frankish state was formed. The Christian religion explained the autocracy of the ruler by the fact that he was appointed by God.
