So let me go get that for you and we'll be right back and we'll teach you more. Alrighty then. So I guess the next big step towards capitalism and market-based economies is going to be the commercial revolution. The commercial revolution, kind of 1500s, right around there, I'm not great with years, but basically the Crusades is what made that happen. The Crusades were a holy war that the Christian world had fought against the Muslim world and along that crusade, which is unsuccessful, you get that scarcity thing kick in. When people find out that there's spices and silks and different raw materials or different products around the world within the mannerism system, that breaks up and you start to develop trade routes with the Middle East. And now you have cultural diffusion and the spread of ideas and the mannerism system is going to break up.
