Translate the following English sentence to French:
"For Flanders, "national minority" in such a context can only refer to a minority which has been established within a certain area for centuries, whilst the French-speakers only moved to the periphery some three centuries ago and have since refused to integrate, which is to be expected in the normal course of events (compare this with the Flemish migration to Wallonia and their perfectly integrated descendants)."
Or, les francophones se sont installés dans la périphérie depuis une trentaine d'années seulement et ont refusé de s'intégrer comme on aurait pu s'y attendre (cf. la migration des Flamands vers la Wallonie et la parfaite intégration de leur descendance).
