Each step costs 100 diplo mana. Note: For empires, their cultural union perk prevents them from switching to cultures within their culture group. You can work around this by shifting to another culture group and then shifting back to your desired culture.
I. Promoting Cultures
To promote a culture: Step 1: Open the Government tab Step 2: Make sure your desired culture has at least 20 dev in states
You can improve the base dev of your desired culture’s provinces. You can also conquer more provinces that have your desired culture. In both cases, turn those provinces into state cores. You can check how much dev you need by hovering over the percentage beside your desired culture.
Step 3: Click the “Promote Culture” button next to your desired culture
II. Shifting Cultures
To change your primary culture: Step 1: Open the Government tab Step 2: Adjust your states so your desired culture has over 50% of your total dev in states You have four ways of making this adjustment:
For provinces that have your desired culture: Turn their territories into states Improve their base dev For those that don’t have your desired culture: Revert their states back into territories Exploit their base dev
Warning: You may lose a lot of income if you choose to revert states into territories. Do that only if your economy can take the hit. Step 3: Click the “Cultural Shift” button next to your desired culture
Benefits of Changing Your Primary Culture
#1: Access to Culture-Locked Formable Nations
The main reason players change their primary cultures is to form certain countries. Most formables are hidden behind cultural requirements. For example, the Mughal Empire is only available to Iranians, Turkmens, Uzbeks, or Kyrgyz. If you shift your primary culture to any of those cultures, you’ll unlock the decision to form the Mughals, even if you started as a distant, unrelated nation. As to why you’d want to do this method instead of just starting as a culturally-related nation, consider these points: This all means that you can create your own combination of ideas and modifiers. You can basically optimize any nation beyond their existing parameters. Note: Culture-shifting for formables is only for fun. You won’t get their achievements with this method. Most of those achievements require that you start as a culture/nation related to the formable.
#2: Access To Larger Culture Groups
If the bulk of your culture group is in low-dev regions, it might be a good idea to shift to a larger group in a better region. It’s more cost-efficient than accepting individual cultures. For example, the Chinese culture group is one of the biggest in the world. They also have a lot of provinces with over 20–30 dev. Instead of accepting each Chinese culture individually, you can save up on diplo mana just by shifting to their culture group. When you become an empire, all cultures in your culture group automatically become an accepted culture.
