Crusader Kings 3 : How to Declare War

Let’s see how to declare war on countries.

Declaring War in Crusader Kings 3

You need two things to war with other countries. These are Casus Belli and soldiers. A strong army means winning wars and ruling the world. After you have a strong military, you should have reasons to declare war against countries. The general name of these reasons for war is “Casus Belli”, such as De Jure Titles or Holy Wars, in Crusader Kings 3. On the other hand, you can declare war without a Casus Belli, but this will negatively affect you.

If you have a strong army and a Casus Belli against the country you will declare war on, you can easily fight other countries to strengthen your country.

After determining the country where you will declare war, follow the steps below:
