Clovis I, king of the Franks, is baptized into the Catholic faith at Reims, by Saint Remigius.

Clovis was the first king of the Franks to unite all of the Franks under one ruler, changing the form of leadership from a group of petty kings 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. Clovis is important in the historiography of France as "the first king of what would become France."

The Franks were originally a group of Germanic peoples who lived near the Rhine-river military border of Germania Inferior, which was the most northerly province of the Roman Empire in continental Europe. These Frankish tribes lived for centuries under varying degrees of Roman hegemony and influence, but after the collapse of Roman institutions in western Europe, they took control of a large empire including areas that had been ruled by Rome, and what it meant to be a Frank began to evolve. Once they were deeply established in Gaul, the Franks became a multilingual, Catholic Christian people, who subsequently came to rule over several other post-Roman kingdoms both inside and outside the old empire. In a broader sense, much of the population of western Europe could eventually be described as Franks in some contexts.
