The border between the empire of Charlemagne and that of the visigoths ran through here. After that the Moors arrived from Spain, controlling an area that extended north of Toulouse. Places like Castelmaur (Castle-Moor) and Castelsarrazin (Castle-Saracen) still bear witness to their presence. When they were driven back south the area came under the control of the Counts of Barcelona, who later got themselves promoted to Kings of Aragon.Umayyad Caliphate did not control southern France for any extended period like they did in Spain.
In fact, way more recently than that, white French people lived in Algeria until Algerian independence in 1960 and the white French went back to France.
Yes there are lots of Muslims in France today but it's not because of anything that happened centuries ago... It's because of immigration taken place in the last 10 years or so.
the moors ( Arabs ) were not as present as they were in Spain for a super long period , but they still were in south of France
prior to that , the Carthaginians ( the ancestors of the moors) were there till the romans conquered France from them
then you had the conquest of Algeria, and the French protectorate of morroco and Tunisia , which was for like 100 years…which brought a lot of Arabs in France , then from the 60s when they retired , they had immigrants coming from there
