If the capitalist or aristocrat is at the top of the POP list when you 'view population' of the province... then he'll be the first one to revolt due to nationalism (it starts from the top). So, give the province to your enemy (for a HEFTY RANSOM *touches extended pinky finger to corner of wily grin*), then declare war, take the province back (along with many others), and there should be some nationalism revolt risk associated with the province now. If you want, you can fire it up even more by editing the save file a bit, should the % get too low. Then the aristo/capi will keep revolting, and you slaughter them mercilessly. Meanwhile, nothing else in the province is ever disturbed.
See, that's Jagdmaus... ALWAYS thinking out of the box, baby.
There's nothing like slaughtering the aristocracy in newly conquered foreign lands. Obviously they are not welcome. And the capis... pah. All the factories are closed, the people are put back in the fields/mines/uniform, so the fat men are obviously no longer useful. STRIKE THEM DOWN...!!
