In my GC with Turkey, I'm in 1620 and I just politically annexed Crimea. It was a good thing the Crimeans had a large army, because revolts began in several provinces of Crimea. I didn't notice any revolts in Crimea before, and I noticed a +3 revolt modifier which can't be reduced due to nationalism. It only occurred in my new provinces, and there isn't any nationalism modifier for any of the Polish\Astrakhan provinces around me, so I don't think that any Ukrainian nationalism event is in play here. So is this a result of the political annexation? If so, how come it didn't occur when I politically annexed Cyrenica? Will it go away after a while?
