Which country has the most interesting history?

I kinda look at the different histories of various regions more like how much did one culture advance in 'x' amount of time. That's more interesting to me. The US advanced incredibly, it's a relatively young nation yet it's a major world power. Places in Africa are ancient as far as civilazation goes, but didn't, and haven't, advanced much. I enjoy the history of the Roman Empire, a lot of parallels can be drawn from that and the US, and it's interesting to use the history to predict the future of a super-power. I also enjoy figuring out where the next big super-poweer will be. My prediction is that South America is up and coming. Give it a decade or two, but I'd buy real estate there now while the getting's good.
