Why can't I release Flanders?

[Pugman]

I have Calais and Picardie as England. Flanders has cores in both. I'm not at war. Why can't I release Flanders as a vassal?

You need a province with the Flemish culture.

You need a province with the Flemish culture.

What's the reason for this? Or is it just another arbitrary thing to have to remember?

 

[TheChronoMaster]

It's because the cores are not the culture of the primary culture of the nation, and you don't control the capital of that nation (Vlaanderen).

Just wait to create a client state, or something.

Pretty much. But it's always been like that.

Just for future reference: Mouse over a grey core shield. If it says 'The nation could be created from this province', or something like that, you can create them as a vassal. If it doesn't, find the province that does.
