I have two allied city-states that are at war with each other. How can I stop this?

    Are you certain they are actually both your allies? If they are both allied to the same person they shouldn't be at war

  • I think it is a bug. This happened to me once. City-states should make peace with any city-state that is not at war with their ally. Commented Aug 25, 2013 at 15:35
  • After I wrote this post, I also pledged to protect them both, hoping they would stop because they were my ally; no luck. Could be a bug then.. Commented Aug 26, 2013 at 9:41

    I thought there was a bug where city-states didn't always declare peace after losing the alliance that brought them into a war. I can't seem to find the mod that fixes it anymore...

This isn't much of an answer, but I feel like it adds enough to be more than a comment. I've done a little research and it appears this case happens exclusively when each city state is allies with different civilization that are at war, thus at war with themselves. When the two city-states are allied to you they continue their wars.

Unfortunately, there is no way to force a city state to make peace with any other entity. Although, it is very rare for a city-state to actually conquer another city.


Could you ask another Civ to go to war with one of the city states and allow it to capture it, then declare war on that Civ and capture the city back and liberate it?

  • Well, that would be tedious..

Actually, I think it IS possible (or at least that's how I did this) but you must be an ally of both city-states. Then you can declare war on one of them → the other one will declare war on him as your ally (which isn't too terrible given the already ongoing war between them ;D). Then you can immediately end the war with the city-state (by declaring peace, even in the same turn!) → this will make your allied city-states also make peace with that city-state (even if their war had been going on before).

It is worth mentioning, that in a city-state that you have declared war on - you will lose all your influence (it will drop to -60, as always when you declare war with a city-state). It is not so terrible if you can easily rebuild it with gold or, for example, freedom ideology skills.

*I'm not sure if it works with only one allied city-state, but I think it should.
