Another important element that decides about the country' integrity is its culture. Each country in the world has its main culture that rises from the Founding Fathers of that country. In some countries, there also is an accepted culture which, although it does not spring from its founders, enjoys the same rights and privileges as the main culture. Some countries become an utter melting pot with five, or more, accepted cultures. An ideal example of such a country is France.

The cultures of the world have been divided into cultural groups. All of the cultures that spring from the same group, as the main national culture, come with limited adverse effects (as long as they are not the accepted ones because then they will have no adverse effects). Every province of the same cultural group lowers the Manpower and Tax modifiers by 15%. While a province of an absolutely foreign culture lowers these values by, as much as, 33%, and will raise the Revolt Risk by 2%, and weaken missionaries by 2%.

The more foreign cultures within the boundaries of a country, the more problems you will have. Is you plan on expanding your boundaries, the range of your cultural group is a good place to start.
