What are the advantages of converting provinces to your religion?

[Epsilon97]

What benefits do you get for converting provinces to your religion? Why is this important?

I am playing Russia. I am interested in the answers to this question generally and specifically as it applies to Russia.

Thanks!!

Revolt Risk is higher in provinces with a different religion, and having provinces with a different religion lowers your Religious Unity, which itself increases 'global' Revolt Risk and the cost of increasing stability.

It also has some negative effects for Catholic players, but since you're Russia that's not an issue.

The game is complex, the wiki still isn´t perfect but it´s a good start. Specially because your next question will be how to convert people fast.
