If its the French Flanders/Crown Flanders/Nord that you refer to, then I'd say that the culture of the area never really changed.
"8. French Flanders
This region in the North of France, roughly speaking situated in the departement of Nord-Pas de Calais, became part of France by the Peace of the Pyrenees in1659, but originally belonged to Flanders. Until today, the regional language remains Vlaems, a Dutch dialect closely related to the dialects spoken in the South of the province of West-Vlaanderen. The city names, like Roubaix, Lille and Dunkerque--Robeke, Rijssel en Duinkerken in Dutch--still prove that this region used to be Flemish.
Since the annexation by France, an active policy of frenchification has been followed. In 1853, French became the language of education. In the last years, there has been a remarkable change though. There is new interest in Vlaems, and lots of language courses in Dutch are organized. The closer economical collaboration over the borders is responible for this, and as a consequence, it's already possible to use Dutch in some hospitals in French Flanders.
The Komitee voor Frans-Vlaanderen (Committee for French Flanders) has played a important role in this. It took initiatives like the reuse of the Flemish names of farms and villages. Since 1984, there is also a local branch of the well known Davidsfonds active in the region.
On short terms, French Flanders won't become part of Flanders again. In any case, it won't become part of the Belgian Kingdom. But on the long term, it would be wrong to consider the region to be lost for Flanders."
Just an interesting little thing about it. "Frenchification" was attempted, but I'd say it had as much effect as Austrian "Germanification".
I think the general picture is somewhat romantisised - original I'm west flemisch (born Izegem) and my last name has its equivalent in French...
I once saw a documentary about French Flanders, only old folks speek the Flemisch, in fact it's something very similar like the west-flemisch spoken by the west flemisch in Flandern.
Youngsters and immigrants have no tendency to speak Flemisch ... the Frenchification is based on " a dominant culture devoring a smaller one by eliminating the bases of a culture (like education in that language, church, socialising, etc.).
The only thing that has opposed the Frenchification is that Flanders - these days - is doing economical better compared to the north of France and that's always better... but when the goverment does not support this (like the French) there is a gradual loss of the culture.
Like "Fryslan" in the Netherlands is actively supported by local goverment, it's thriving...
Lots of French speaking people in Belgium once were Flemisch, this tendency of Frenchification is the best example - together with the more dreadfull Ottoman principle of the Jannisars (abducted Greek children converting them to the Islam) and the exponent example of Nazi and Communist beasts that broke lots of local cultures by shipping them around up to Siberia...
It seems culture change has different levels and is of all days =
1 - natural process, what is the dominant culture by nature,
2 - forced, by conquest and elimination of base structures,
3 - enforced, prohibit the native language,
4 - take over, convert people like Ottomans did - for me the Christian baptising paradigma is not here - that didn't break cultures!
5 - destroying cultures - deport them (Nazi and Communist),
