How to get AIs to fight amongst one another

I've been wondering- what actions can I take in the editor to get Civilizations to make war amongst one another. I think everyone can agree the game is a little more fun and interesting when the player isn't the one engaged in war. Can anyone offer any advice?

Make an invisible unit available (Attack=1, Def=1 and able to pillage and capture), and AI will build them a lot and send them out on exploration. Whenever an AI rival unit moves into the same tile as the invisible unit, war is triggered. With many civs and cities, the game can become pretty volatile.

Or add units with hidden nationality to each civ, they might have a peace but units itself will be slaughtering each otter.

Not sure what your circumstances are, but if your doing this for a scenario, you could either make the AI seem more powerful than they are by giving them super attacking immobile units or since the AI is programmed to go after strategic resources give a resource to a certain civ that one civ needs for a unit, building, etc and they will attack them to get it. I also asked this question to a couple of people. There are also a few other things which the AI also respond to negatively (may not be the best word), the AI can act a bit differently to civs in a different culture group. The AI can also act a bit negatively to people that have a favourite gov that is shunned for them.

If you have a preset map that requires building, the AI tend not to attack much if there is still building space, so if you make a big map you should think about this and adjust accordingly the settings and the amount of civs, so the AI will not constantly build. You may even want to make certain tiles unable to build upon.

These are things ive learned after making quite a few scenarios.

Also the strategic resource thing can also work if you dont want a certain civ to attack a civ, but instead you give both balanced resources so they dont need to attack each other to get a certain resource.

In the Scenario Properties section there's "Locked Alliances" (or smth like that) tab. You can set alliances which will be constantly in war with each other. Drawbacks - they'll never sign the peace treaty (1), they'll weaken each other (2).

Set the Civs powerful enough to go to War either from the start or later as you like. Each CIV wants to gain the world and if they have the power, they will go to War with other CIVs to gain what they have, be it a resource or merely their land. This is especially true IF the way to Win is Conquest rather than the other ways to Win such as Own the Most Territory, etc...

The reason Civs build as many Cities as they can by default is for Power... Domination and the ability to take all later. IF you have a Scenario where the Civs cannot build any new Cities, they will go after the other Civs to gain more.

Constant War is OK in some Scenarios with Locked Alliances. War Weariness is something that has to be addressed if that is done but easy to do.

The easiest way to have CIVs go to War is indeed using invisible Units and setting them with the Scout flag because other CIVs run into them and that causes War. Of course this requires that the CIVs are close enough to run into them on the Map.

IF a CIV is perceived as being Very Powerful or will become Very Powerful later, the AI will go after that CIV as soon and as much as they can when they themselves have enough Power to go after them. Generally this happens to be the Human Player but settings can be made to provide more Power to CIVs. Just keep an imbalance of the Power or all will be a "stalemate". Power can and should be adjusted so each CIV can gain Great Power at different times. This provides the "Power Conflicts" at different times for the CIVs and that causes Wars because the AI wants to limit or stop them and it provides a way for each CIV to possibly become the Dominant CIV in the game. Generally, if a CIV has the Power they will use it

All of the above Posts concerning this are correct. Just a matter of what you are wanting for a "Normal" game or a Scenario.

Perhaps a simpler solution:

1. Put the Civs you want at odds in different Culture Groups (increases odd of warfare)
2. Give Civs very high Aggression levels.
3. Use "shunned governments:" e.g., in my 18th Century Mod, Sweden's Gov Type is "Protestant Monarchy" whereas its "shunned type" is "Tsarism;" Russia's Gov Type is "Tsarism" with its shunned Gov "Ottoman Empire," etc.

Also, IIRC having "Mutual Allowed Passages" treaties enabled tends to make all Hades break out ...
