Galicia in the NW served as a launchpad for an invading Cornish army to begin an entirely different Conquest.
Substantial numbers of French knights adhered to the cause of Carvajal, Castile and Leone over the several centuries it took to achieve dominance, but the "native" people in the South did nothing other than become good Moslems!
Then, as the Reconquista was wrapped up, most of the Moslems and most of the Jews then in Spain who had not already become Christians, did so.
There really wasn't any mass explulsion of any kind. People were given a choice and took it.
