Frankish king: Clovis (466-511)
Managed to unite all the Franks into one Frankish Empire.
How?
Two reasons:
1) Good army leader and defeated many enemies
2) He worked closely together with the Christian Church in Rome. --> Why? They could help Clovis govern his empire, because they were educated and had become very powerful!
