Culture groups in 1444
Individual cultures in 1444

Culture icon.png In the game, cultures are divided into groups. Each province has one dominant culture, and each country has one primary culture and possibly one or more accepted cultures.

Primary culture[edit]

All countries have one primary culture. This is normally fixed, although the "Accept Cultural Shift" decision can change it, as can certain national decisions.

For the cultural shift decision to be available, your capital must be situated in a province that does not have your primary culture. To then enact the decision, the culture in your capital province must be the dominant culture in your nation. The culture with the most provinces in your nation defines which is the dominant culture, for the decision, this can be greater than or equal to any other culture type.

Accepted cultures[edit]

Many countries have one or more accepted cultures alongside their primary culture, and they may change over time. These cultures comprise a significant minority, or even majority, of the country's population, and are treated as well as the primary culture.

A culture will become accepted if owned, cored provinces of that culture provides at least 20% base tax of total base tax from all your cored provinces . If the tax percentage drops below 10%, accepted cultures will be lost. With the 'Cultural Ties' idea, from the 'Humanist' Idea group, the percentage needed for accepted cultures is lowered to 10% and loss of accepted cultures is reduced to 5% of the total base tax.

Accepted culture threshold

These national ideas and other modifiers reduce the base tax needed for a culture to gain acceptance.

In addition, Cultural Unions such as Scandinavia, France, Spain and Byzantium will automatically accept all cultures within their respective culture group. (e.g. French cultures for France, German cultures for Germany and so on). As of patch 1.6, this applies even if a nation's primary culture isn't of the union group (for example, if Navarre forms Spain, all Iberian cultures will be accepted even though Basque is in a different group).

Penalties for unaccepted cultures[edit]

A province with a non-accepted culture will pay less tax and have higher revolt risks alongside other penalties. A province of a culture in the same culture group, but not the same culture as the owner will get lighter penalties:

Culture change[edit]

It is possible to change the culture of a given province.

25 diplomatic points per base tax[1] (100 for a base tax 4 province for instance) are needed to change the culture of a province to your primary culture. Overseas provinces are converted at 5 diplomatic points per base tax (no longer true). Changing culture takes 24 months per base tax.[2] Like coring, building and converting, a siege will suspend this, and cancel it if it succeeds. Furthermore, the region must have the state religion, be a core, and not have Nationalism in order to convert culture. Culture also cannot be converted if the primary country of that culture exists.


These ideas and other modifiers reduce the diplomatic points needed for a cultural conversion.

Primary nation[edit]

Most cultures have a "primary nation." The primary nation of a culture will keep uncontested cores indefinitely, as opposed to 150. Primary nations for each culture can be found in the list below.

List of culture groups[edit]

Note that culture groups are not just based on linguistic criteria - for example, Turkish is in the same group as the Semitic peoples due to cultural similarities and gameplay purposes, rather than Altaic.

Primary nations of each culture are listed to right of each culture. Struck-through nations are listed as primary nations in the code but only receive 150 year cores in-game.
