History of France
Gaul
Settled mainly by the Gauls and related Celtic peoples (apart from a shrinking area of Basque population in the south-west), the area of modern France comprised the bulk of the region of Gaul (Latin Gallia) under Roman rule from the 1st century BC to the 5th century AD.
Franks
In 486, Clovis I, leader of the Salian Franks to the east, conquered the Roman territory between the Loire and the Somme, subsequently uniting most of northern and central France under his rule and adopting (496) the Roman Catholic form of Christianity in preference to the Arianism preferred by rival Germanic rulers.
