This page appears to be only for episode one of four, yet my comments are for all four episodes, each running just under one hour.This is a high quality PBS production, I was able to watch it on the 2-DVD set from my public library. Not only is the subject fascinating, leading right up to our modern cities and modern civilizations, but one can't help learning a lot about the history of the world. Good series.

War is necessary to civilisation & advancement? I don't think so!
