About Crusader Kings III
Crusader Kings III lets you pick a noble house and guide its dynasty through the Middle Ages. You can start in 867, 1066 or 1178, and every decision shapes the future of your heirs and realms.
The game spans from the Nordic north to Burma in the east, filling the map with peasants, knights, courtiers and historic figures. Traits, lifestyles and genetics affect each character, while you can customize appearance, titles and even create a new faith.
01 / THE GUIDE
Dynasty Management
Your lineage continues after each ruler’s death; the next heir automatically becomes playable and inherits titles, traits and any genetic traits passed from parents.
You can influence an heir’s development by assigning guardians or educating them yourself, and you may arrange marriages or remove unsuitable heirs by other means.
- Select guardians whose traits complement the heir’s strengths.
- Arrange marriages that bring titles without needing war.
02 / THE GUIDE
Realm Governance
Granting or revoking titles, adjusting laws and taxes, and appointing councilors let you keep vassals loyal and your treasury healthy.
Building castles, bastions and cultural innovations raises wealth, prestige and security, while designing a faith can shape long‑term development.
- Balance tax rates to avoid serf unrest.
- Invest in fortifications before hostile neighbors appear.
03 / THE GUIDE
Military Operations
Armies consist of men‑at‑arms, knights and mercenaries; you can also hire Holy Orders for major conflicts or raid nearby lands for loot.
Agents can sabotage, blackmail or murder rivals, adding a covert layer to warfare that can turn the tide of battle.
- Mix knights with men‑at‑arms for balanced combat power.
- Use mercenaries when your own levies are insufficient.
04 / THE GUIDE
Faith and Culture
Being pious attracts religious allies, while creating a new faith lets you tailor doctrines to your strategic goals.
Cultural innovations improve technology, architecture and societal bonuses, influencing both economy and military strength.
- Earn piety before declaring holy wars for extra support.
- Adopt cultural innovations that match your strategic focus.
