it should be -15 to revolt

In the civilopedia for warriors it says they form up when their civ needs them, then disperse when the threat is dealt with. Warriors for uprising could be a really good idea

Is it compatible with Vanilla?

if you get -30 unhappiness in hte game without mods there would be a revoultion. three or more units spawn near you capital and are as advanced as you most advanced foot soidier(e.i swordman,musketman,rifleman,etc) this happended to me on numerous occasions when i completety ignored happiness while taking a lot of cities but it is very rare to get you happiness below -20

But is it compatible with "Revulotion" mod?
Just wandering

what happens to cities if they fall to the uprising

Oh okay then. Also, I'll check compatibility if I'll can

I don't know if it is compatible with other mods, please check it and report if you can. Answering your question - no, definitely no. This is the idea - in case of big problem you get the units that can help you to survive. People accepts you as a leader and they want you stay there - that is why you can control the insurgents. It is not the revolution - it is uprising!

Also, dont you think that those units that spawns should be barbarian to depict that the defeated player can not control them, and not to overload that unit's money pool?

First of all I think regular infantry units are fine. Second of all pla let me know if your mod is compatible with "Revolutions" mod and that one with the culture expantion of the borders? It may appear that they are compatible not.

If there will be any interest, I will extend it a bit. The plan is:
- arbitrary unit can spawn
- not only one kind of unit will spawn at the same time
- uprising possible also before Renaissance era

Would be nice to add specific models for some civilizations (like Polish Insurgents that are already included in Polish Empire Mod). But this requires a lot of time and therefore I will do it only if there will be enough interest.

What about more early eras?
