How to Get Casus Belli in Civ 6

▶

To get Casus Belli in Civ 6, you need to reach the Renaissance Era with the Civic Diplomatic Service in the civic tree, which provides a Casus Belli to use against another leader or civilization, but before using it, you must first denounce the civilization you wish to go to war against. The Casus Belli system allows for more nuanced and strategic warfare, enabling players to declare war with a justifiable reason, such as “Holy War” or “Liberation“, and avoiding unnecessary warmonger penalties.
