Diplomacy

The key to the first half of a diplo game is to avoid negative attitute modifiers. The early positive modifiers will expire before the final vote, but negative ones last forever.

- You traded with our worst enemy!
Before trading techs, look at the international reputation of your partner. If anyone is annoyed with them, don't trade! I only had 2 trade partners for most of the game (Huayna Capac and Asoka), and they were all I needed.

- You refused to stop trading with our worst enemy!
- You stopped trading with us!
Don't sign open borders, unless you have a real strategic need to do so.

- You declared war on us!
- You declared war on our friend!
Don't declare war.

- You have fallen under the sway of a heathen religion!
Don't adopt a state religion. I spread Confucianism for border expansions, but never switched to it.

- You refused to give us help!
Give in to all demands, unless they want you to declare war or convert religion.
