Understanding the intricate tapestry of cultures and traditions is fundamental to success in Crusader Kings III. Your character's culture dictates their starting traits, available innovations, and even their opinion of other characters. Each culture possesses unique traditions, which are powerful modifiers that can significantly impact your realm's development, military strength, and social cohesion.
Cultures
When you begin a new game, you'll select a starting character, and their culture will be a defining aspect of your playthrough. Cultures are organized by culture groups (e.g., Norse, Iberian, Persian) and then by individual cultures within those groups (e.g., Norse, West Germanic, Andalusian). Different cultures have different starting technologies and can adopt new innovations at varying speeds. For instance, a character of the Norse culture might have an easier time adopting seafaring technologies, while a character of the Byzantine culture might benefit from advancements in administration and warfare.
Traditions
Traditions are the bedrock of cultural identity and offer substantial bonuses or penalties. These are unlocked as your culture progresses through the innovation tree. Examples include:
- Warrior Lodges: Grants combat bonuses and unique martial events for cultures that adopt it.
- Syncretism: Allows for easier religious conversion and can reduce religious hostility.
- Feudal Elective: A succession law that can be adopted by certain cultures, influencing how your titles are inherited.
- Gavelkind: A succession law that divides titles among heirs, often leading to fragmentation of your realm.
As your ruler, you can actively work to develop your culture by investing in innovations. The higher your cultural acceptance and the more innovations you research, the more traditions you can unlock and adopt. Be mindful of your neighbors' cultures; high cultural acceptance with a neighboring culture can lead to easier assimilation of provinces and characters, while low acceptance can breed dissent and rebellion.
Cultural Acceptance & Assimilation
Cultural acceptance represents how well your culture is integrated within your realm. Provinces with a different culture than your own will have lower acceptance, making them more prone to revolts. You can increase cultural acceptance through various means, such as appointing a steward with high learning to the "Promote Culture" task in a province, or by having your ruler adopt a fore culture through an event. Conversely, you can also choose to convert fore provinces to your culture, which takes time and resources but can lead to a more unified and stable realm.
