You must be at war with one civ first, then you can form an alliance against them with second civ. Otherwise "they would never accept such a deal".

Depends on the difficulty to determine how often they will spontaneously declare war. On monarch I have seen the ENTIRE world declare war on one civ in just 2 turns, however I have also seen the game last until we had MA to see anyone but me declare war...
Depends on resources, terrain, techs, power, culture, anything can trigger wars between comps.
One thing that worked better than I could've hoped was using a stealth bomber between two civs, they declare war on each other probably thinking it was the other one...
Pretty much what the AI does, goes to war, makes an alliance with me against 3rd party, then soon after, breaks alliance and makes peace with 3rd party, leaving me in war.Originally posted by papamaverick
Yeah, best way is to declare war yourself, sign an alliance, and then simply sue for peace after the 10-turn deadline. They won't let you talk to them before that, but afterwords they're almost always peace-inclined.

But I was worried they would co-opt the americans (big civ as strong as me - but of course with more units already built - on the same continent, and I have a huuuuuuge border with them) into joining them. So I went to the americans, and gave them all my money and gpt to join the war. They joined. Soon they got the french, a big meanie on the Russians' continent, to join, as well as a couple other unimportant civs... About 40 turns later the russians were destroyed by the rampaging french forces

i usually don't worry about how to instigate wars, but that my allies might beat me to the cities i want. in which case, i might also declare war on them.
(heh, i never aim for the diplomatic victory anyway!)
