War Score
From the game's encyclopedia
A measure of which side is winning in a War. It goes from -100 to 100, with e.g. -25 for one side being 25 for the other. At 100 War Score, you can force the other side to accept your Peace Offer.
War Score can be gained by:
• Imprisoning the enemy Ruler or their Heirs (not including their Allies)
• Occupying enemy Holdings (especially within the War Target)
• Occupying the enemy's Realm Capital
• Controlling all Objectives for an extended period of time
