This mini-mod consists of events and decisions that simulate the migration of people of different religions from one province to another, and also the religious minorities that exist in each province.
Let me explain it a little better with a few screenshots:
Here we can see Ile de France has a protestant majority
However, reformed refugees have arrived from neighbor provinces Cambray and Othe...
Cambray, on its hand, has some protestant people, maybe refugees from Artois...
... or maybe "induced" people from Ile de France, who are trying to spread the protestant faith!
Pernambuco has received some slaves from Portuguese Zanzibar...
And protestants from Caracas are colonizing neighbor Cumana.
Here's some more details:
An event warns you when a minority appears in one of your provinces.
An event also warns you when that minority is getting larger.
When the minority reaches a certain number, the province will switch religions; the minority will become the province main religion, and the province will get a minority of the previous religion.
Owning a province with slaves will cause them to spread that province's faith throughout your colonies and overseas possessions.
People from neighbor provinces can (and will) move to your provinces if certain conditions are met (normally if they're of a different religion than their owner country, if the revolt risk is high, etc.)
There's a province decision to encourage religious emigration (and another to cancel it) that will cause your people to move to neighbor heretic provinces and create/enlarge minorities there.
PLEASE give me some suggestions and ideas to improve this mod further, and some feedback on how you liked/hated the mod if you happen to try it out.
DISCLAIMER: This mini-mod is in its "beta" phase. It may contain bugs, and it may crash your game. It has worked fine for me for dozens of years, though. It also may not be properly balanced as of now.
