For some reason the Zulu never improve toward me. If they get cautious they will never become polite unless I get an alliance with them. Even when I give them techs they stay the same. Most times they eventually become furious with me for no reason. Is it normal for them to never become more freindly. i usually just get so mad that I demand stuff from them just to make them furious.

I don't have the link on hand, but I know Bamspeedy wrote an article about AI attitude that explains everything... I don't remember is fully, but it explains that the attitude has to do with current deals, culture groups, governments, etc. Besides, the Zulu in particular are very aggressive, and I thought (not sure about this though) that that affects attitude as well.

Is this the thread you are talking about? (http://forums.civfanatics.com/showthread.php?s=&threadid=44999)

I just left a game (playing as Monkey Faced Twit of the Smelly Morons, formerly known as the Ottomans:lol: ) where I noticed a alot of Zulu units massing near one of my cities that only had a warrior defending. Before anything happened (they werent even in my city radius yet) I gave them 250 gold hoping to buy some breathing space so I could build up defenses, but they went ahead and attacked me anyway, even after they said that my gift went a long way to bringing the Zulus and the Smelly Morons closer together. I saved before offering them the money so I'll go back later and try maybe offering them more or rush building a spearman at least. Oh and a couple of turns before this happened, they wiped out the Persians. Aggressive seems to be the keyword when it comes to the Zulus, in this game anway, although Ive seen them behave occasionally like fat happy housecats too lazy to chase a mouse.

Having a ROP agreement with a civ usually keeps them polite towards you. But you have to be weary of sneak attacks even with a ROP agreement.

Dumb: In your situation, reloading wouldn't stop the Zulus from attacking you. They made the decision to attack a few turns ago.
