Religion is an important element of Crusader Kings 3. Often, an area or person’s faith dictates your relationship with them. Religion in CK3 also controls marriage doctrines, criminal doctrines, how your clergy works, and any special doctrines. Your faith also influences how you can gain a significant resource in the game, Piety. There is an immense list of religions in CK3, and you can find every one below.
How does Religion work in Crusader Kings 3?
Each character in the game is assigned a default religion. This is usually closely linked to their culture and region. So, you can expect Europe to be mostly Christian and Pagan, the Middle East and Northern Africa to be Islamic, and the East to be a mixture of Buddhism, Taoism, and Hinduism.
Each religion stems from one of three religious families (which are closely linked to region and culture):
- Abrahamic
- Eastern
- Pagan
Within these families, you’ll find a massive amount of different faiths. In fact, religions within the same family don’t necessarily have anything to do with one another. For example, Islam and Christianity are both Abrahamic faiths but are antagonistic to one another.
Instead, it’s best to think of your religion as rivaling every other religion. Here are the different modifiers you can get depending on your faith:
Righteous
- This faith is considered legitimate:
- Intermarriage is common.
- Can Usurp their titles.
Astray
- Character is of a similar faith (ex. Insular Christian and Catholic):
- Intermarriage may still happen. Character Opinion: -10
- Popular Opinion: -15
- Can Usurp your titles.
Hostile
- Character’s faith deviates significantly:
- Intermarriage may still happen.
- Holy Wars can be waged.
- Character Opinion: -20
- Popular Opinion: -30
- Can start Great Holy War against them.
- Cannot Usurp their Titles.
- Can use Holy Orders against them.
Evil
- This faith is considered anathema:
- Intermarriage rarely happens.
- Holy Wars can be waged.
- Character Opinion: -30
- Popular Opinion: -45
- Can start Great Holy Wars against them.
- Cannot Usurp their titles.
- Can use Holy Orders against them.
These modifiers can be to your detriment when you’re playing a diplomatic character. However, if you are more martially inclined, you can use them to justify military action and conquer lands.
