Dynamic Culture Conversion

(for EU4 1.22.x, available in English, French, German and Spanish)

Have you ever wondered why the culture of provinces does not change dynamically even if the same country owned a province for houndreds of years? This mod enables such dynamic culture conversions.


Since no existing files are changed, the mod should also be compatible with any other mods used. It will also work with any cultures added or altered by other mods. Since version EU4 1.14 all cultural unions are now correctly identified as such, because they depend solely on the government rank now (or total development if playing without 'Common Sense').

While using this mod no achievements can be earned.

The mod can be turned on and off in any saved games without any issues. The save might be marked as incompatible by the game afterwords, but it can be loaded and played without any problems.


If a province suitable for a culture conversion exists, an event will be triggered. After some time, the culture of a province will change to the owner's primary culture or to an owner accepted culture. The MTTH will normally be between 65 and 130 years for changing to the primary culture and between 90 and 190 years for the spreading of accepted cultures. However, the MTTH can be much higher or lower depending on the exact conditions. The owner can always prevent this change which will in return grant some small temporary bonuses.

To trigger the events, the following conditions must be met:
- The culture of the province is not currently changed by force
- The religion of the province has to be tolerated (i.e. positive tolerance)
- The province must be a core province of the owner and has to be under his control
- The province has to be free of separatism and must not have an autonomy value above 80
- At least one neighboring core province of the same owner, which is also under the owner's control, must have the culture to which the current province will change

The mean time to happen after those conditions are met is reduced by:
- The province is completely surrounded by provinces of the owner's culture
- The province is in the same area as the owner's capital
- The ideas Adaptability and the effect Inquisition
- A tolerance towards the religion of the province of at least 2
- High prestige (above 89) but only if the stability is also at least 2
- Being a coastal province
- Some buildings: market places, trade depots, stock exchanges and universities
- The government type administrative republic
- The owner being a colonial nation

The MTTH is increased by the following:
- If the province is the last province of that specific culture
- The ideas Local Nobility and Cultural Ties
- The culture is an accepted culture or belongs to the owner's cultural union
- The culture of the province is not in the same cultural group as the primary culture of the owner
- Local autonomy, the steps are: 5%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%
- Being granted to an estate (this will increase the MTTH only slightly)
- Development below 7 -- except for hordes if the province is located in a plain like terrain -- or above 15, steps: 16, 26, 46
- Harsh terrain: glacier, hills, mountain, jungle, marsh or -- if not a horde -- savannah, desert and coastal desert
- The government type enlightened despotism if the culture of the province is an accepted culture
- The province being part of a trade company
