DIPLOMACY
As Civilization IV progresses and your units explore the world,
you will meet the leaders of the other civilizations around you.
Each leader is different: some are warlike; others, peaceful.
Some are backstabbing liars; others are (usually) honest.You’ll
have to learn how to deal with these characters: some you’ll
fight right away; others you’ll negotiate with – at least until it’s
time to destroy them a few centuries down the line.
You can accomplish a lot through diplomacy. You can trade
technologies, resources, maps, gold, and even cities. You can
form mutual protection pacts; you can declare war; you can
negotiate peace settlements. Success in Civilization IV depends
as much on your diplomatic skills as it does on your martial
and management prowess.
LEADERS
Each leader has his or her own agenda. They, too, seek to
achieve victory – some through force of arms, others through
technological prowess, others through cultural domination.
You’ll get clues to their intentions as the game progresses – the
more warlike leaders will usually not trade anything of military
value, the knowledge-focused leaders will seek advanced tech-
nologies, and so forth. See “Advanced Civilizations” and the
Civilopedia for more details about each leader.
Leader Attitudes
During the game, each leader will form an opinion of you:
how great a threat you are to their civilization, whether you
have fought them in the past, whether you have allied with
their enemies, how much you can be trusted to keep your
word, etc.
Leader attitudes come in five flavors: friendly, pleased,
cautious, annoyed, and furious.The more a leader likes you,
the more likely he or she is to be willing to trade with you, and
the better deal he or she will give you.You may be able to trade
with hostile leaders, but you’re likely to pay a stiff price for
whatever you get.You can check your relations with any leader
with whom you have contact by [rolling over] that leader’s
