With the exception of Roussilon and a few other bits of southern France that were once part of Catalonia/Aragon (https://en.wikipedia.org/wiki/History_of_Spain#/media/File:506-Castile_1210.png https://en.wikipedia.org/wiki/History_of_Spain#/media/File:5...). Before that some of the area was part of the Umayyad Caliphate at their peak (https://en.wikipedia.org/wiki/History_of_Spain#/media/File:Map_Iberian_Peninsula_750-en.svg https://en.wikipedia.org/wiki/History_of_Spain#/media/File:M...). Before that is was part of Visigothic Hispania (https://en.wikipedia.org/wiki/History_of_Spain#/media/File:Hispania_700_AD.PNG https://en.wikipedia.org/wiki/History_of_Spain#/media/File:H...). Also, unlike much of Spain, Catalonia was never under Carthaginian control. So for much of history Catalonia and parts of Occitania were tied together to varying degrees.
