In-Depth Description

The add_cb command in Europa Universalis IV (EU4) is used to add a casus belli, also known as a cause for war, against a specific target country.

Casus belli are various reasons a state could use to start a war and are presented in game as specific war goals.

To use the command, you would need to input add_cb [casus_belli_id] [target_country_tag] [source_country_tag].

The casus_belli_id is the ID of the casus belli that you want to add. The target_country_tag is the tag of the country that you want to declare war on, and the source_country_tag, which is optional, is the tag of the country that you want to be able to declare war.

This command is useful in situations where you want to have a justified reason to go to war against another country without suffering the unstability that usually come from declaring an unjustified war.

For instance, you might want to use it when you are playing as a small nation surrounded by larger countries and need a valid reason to expand your borders without aggravating other countries too much or dealing with the internal repercussions of an unjustified war.

Type your command into the console, and then press ENTER .
