Co-belligerent question in eu4

[Sam_Orda]

Hello!

A quick qustion regarding designating co-belligerents in a declaration of war and the war score.

If in a war I have two opponents in which I designate the secondary one, the ally, as a co-belligerent, when I conquer all the provinces of the main opponent without conquering anything from the secondary one, will I have a lower or higher war score than if the secondary opponent was not designated as a co-belligerent?

Thank you.

Designating a co-belligerent has no bearing whatsoever on the warscore cost of the main target's provinces.

Worth pointing out is that you can safely cobelligerent HRE states if you declare on a member that is rivalled by the emperor. He still won't intervene even if he would have in case you had declared directly against the cobelligerent.

My thought was that if you name a co-belligerent in the declaration of war, to have 100% war score you must conquer not only all the provinces of the main target but also those of the co-belligerent.

You don't. Designating another country a co-belligerent just removes the warscore cost and aggressive expansion penalties you'd otherwise incur when taking their land in a peace deal. Earning any war score in a war is independent of that, you can get 100% after a set amount of time if you fully occupy the main target only. Designating another country a co-belligerent could actually decrease the overall warscore you get from occupying provinces if they end up calling in their own allies into the war who otherwise wouldn't have participated, but as you peace them out separately during the war you end up back where you would've been without co-belligerenting the secondary target.
