I've tried doing a search but couldn't find any...so apologies if this is a repeated thread. I have been playing Civ4 for about a week now and just finished a warlord level game. My question is: How do you force another civ to start a war with you? I have tried doing the following but to no avail: - Demand tribute (gold) - I tend to get up to -20 reaction after multiple "demand tribute" but it seems to stop at -20 and the civ just become furious. - Stop trading - Stop open borders My military is quite strong...is that the main reason? I was also thinking of using spies and setting them to sabotage some buildings...hopefully they would fail and the civ will become even angrier!
