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 with possibly one or more accepted/promoted cultures

Primary culture

All countries have one primary culture. This is normally fixed, although it can be changed either through the culture mechanics or via certain national decisions.

Any accepted culture that has at least 50% of the total development of the country can be promoted to the primary culture of the nation.Changing your primary culture costs 100 Diplomatic power.png diplomatic power.The player's previous primary culture will consequently change as an accepted culture. The AI will never take this decision.

The player has the ability to promote a culture to make it accepted or to demote it, removing it from accepted cultures.The player can promote any culture in his nation that has at least 20 cored development in a state. It costs 100 Diplomatic power.png diplomatic power , but can be advantageous in the long run. Removing a culture from 'accepted cultures' costs 10 diplomatic and adds +5 National unrest.png unrest in all provinces with that culture, that will decay over time.

Cultural union

Cultural unions will automatically accept all sub-cultures within their respective culture group. Any nation can become a Cultural Union (CU) of its culture group upon reaching the Empire rank Empire government rank or 1000 development if the player does not have Common Sense. As part of this change it is possible for several nations to be a CU for the same culture group. A nation can become an empire as part of a decision, event, reaching a certain development level or by upgrading the government rank; Cultural Unions make it so brother cultures don't have to be promoted to be accepted by the country.

Penalties for unaccepted cultures

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

  • Same culture group (Culture name will be in yellow, will have a star next to their names on the culture tab)
Local tax modifier.png −15% Local tax modifier
Local manpower modifier.png −15% Local manpower modifier
Local sailors modifier.png −10% Local sailors modifier
  • Different culture group (Culture name will be in red)
Local tax modifier.png −33% Local tax modifier
Local missionary strength.png −2% Local missionary strength
Local manpower modifier.png −33% Local manpower modifier
Local sailors modifier.png −20% Local sailors modifier
Local unrest.png +2 Local unrest

Republican Cultural Sufferance

Republics get an additional cultural sufferance modifier in different culture-group provinces. This stacks with the usual penalty, mitigating but not eliminating it.

Local sailors modifier.png +5% Local sailors modifier
Local unrest.png −0.5 Local unrest

Culture change

The culture of a province can be changed to another culture if the province is cored by its owner, has the same religion as its owner and has no Separatism unrest. The cost for converting culture is 10 diplomatic power per development[1] and the duration for the change to take place is 10 months per development[2]. Like coring costs, culture conversion costs are capped at 30 development, so improving a 30 development province will not increase the cost of converting its culture. Sieges and occupations will pause culture conversion but will not cancel it, the culture conversion will continue as soon as the province is liberated, although conversion will be cancelled if the province's ownership changes. If the conversion is cancelled before progress reaches 10%, all diplomatic points will be refunded.

A province can have its culture changed to the primary culture of the province's owner. With The Cossacks, a province's culture can also be changed to any neighbouring province's culture or its culture can be restored to whatever it was originally. Changing to neighbouring culture can be beneficial if the neighbouring culture is accepted or close to being accepted.

Converting a province from culture A to culture B will incur a relations hit with every country whose primary culture is culture A.


The cultural conversion cost modifier reduces only the diplomatic power needed to change a province's culture. The time needed for the change to be complete cannot be reduced.

The following modifiers apply:

−25% if the province borders another owned province with the desired culture (adjacency bonus)
−50% if the province is being restored to its original culture

Primary nation

Most cultures have a "primary nation." These nation will keep uncontested cores indefinitely,[3] so long as their cores are in provinces of their culture - culture conversion will force these cores to obey the normal 50/150 year expiry timers for cores depending on whether or not the new culture is the same culture group as the nation with a core there. Primary nations of each culture can be found in the list below.

Culture Shift

To be able to "shift" the country's primary culture and set a new one if said country is at least in 50% of the country's cored state development, it costs 100 Diplomatic power.png diplomatic power, and substitutes the previous' "Culture Shift" decision.

It can be advantageous for a player to set a new primary culture to be able to form a country with a different tag ( With new national ideas ) or to be in a larger culture group, to have more brother cultures and save promoted cultures slots.

Lost cultures

Cultures in the Lost Cultures group do not exist at game start, but can be created as custom nations or during the invasion. The only culture that can be re-discovered is the Roman culture by Restoring the Roman Empire that change the primary culture of the nation. All provinces with the former nation's primary culture will change to Roman culture.

Culture groups

Note that culture groups are not just based on linguistic criteria - for example, Romanian is grouped with the Carpathian cultures due to cultural similarities and for gameplay purposes, even though Carpathian is not a linguistic family.

Primary nations of each culture are listed to the right of each culture.
