As the Netherlands, I'm on a quest for world domination. My current enemies are Great Britain, Spain and Portugal, and I would love to take over their colonies. In my last war against GB, I annexed all of British Columbia, thinking it would immediately trigger into forming Dutch Columbia. But it didn't. Instead I was left hanging with 175% overextension. (Although I didn't get any rebels or events. Also, I don't think I should get overextension for overseas provinces. Anyone know what's going on here?) However, once one of my nearby colonies became self-sustaining, this triggered the entire area into forming Dutch Columbia.

So if I want to take over enemy colonial nations, I should just annex them, ignore the overextension, and then settle nearby. Once the colony finishes, the entire region will form a new colonial nation. However, many of the colonial nations I want to conquer don't have free land nearby (or in some cases, I'm unsure as to whether the nearby land falls under the same colonial region). How do I get these colonies to trigger?

If anyone else is having this problem, you just need to core 5 provinces, or the amount of provinces you need to have 5 in that place. You dont need 5 to colonize, you need 5 cores to make a colonial nation. Of course, colonize give you free cores.

  • This is certainly the right answer now. Not sure if this was already the case at the time of the question (2 and a half years ago), but that doesn't really matter.

I also asked this question on the Paradox Forums, where Heliocon and londoner247 were kind enough to answer.

In the words of londoner247:

Once you have five cored provinces in a Colonial Region then all the provinces you control in that region will switch to your new Colonial Nation and they will get cores on all of them. So, in your situation, if you can handle the overextension and there are five spare provinces in the Colonial Region (assuming you have no colonies there already) then your best bet is to build five colonies and let it all switch at that stage.

If you conquer territory in a Colonial Region where you already have a Colonial Nation then each province you take will immediately switch but without a core so your Colonial Nation may get overextension issues and you may need to keep an eye on it to help with the rebel stomping.
