Found a stratagy..

[Avahz Darkwood]

This happend by accident. I had three resources that I could trade. Gems, Silk, and something else. These were luxery in nature. So I traded them to a nation nearest to me. Eventually I figured what Luxery tradeing did. So out of ceriosity I just *gave* them those rescouces. They had 3 luxery points to keep their ppl happy. I then invaded them. Stoped the trade routes and noted that almost half of their cities whet up in smoke (riots). I caused them to count on my goods for their nation and as soon as I felt like it, they were mine and crumbled easily.

Of course seeing that they had the only reserves left of Iron (mine we depleted) I had no option but to invade...
