If a free city or an HRE member is marked as a co-belligerent neither the Emperor nor the Emperor's allies will be called in. A similar loophole also applies in the HRE. Note: If a nation is marked as a co-belligerent, but are also a tributary of another nation, neither the tributary overlord, nor the co-belligerent's allies will be called in. Taking that country's provinces will cost the same as the war leader's provinces.If that country has a guarantor, it is also called to war.That country can call on its own allies to fight as well.If a country is marked as a co-belligerent: Taking that country's provinces in a peace incurs +50% aggressive expansion and costs +100% warscore.Beware that the Holy Roman Emperor defending the empire is always a co-belligerent. That country can't call its allies to arms in that war (but its subjects are called as normal).If a country is not marked as a co-belligerent: If opinion is higher than 150, penalty increases to -2 stability and +2 war exhaustion.
