[[Jared Diamond]] in his award-winning books, Guns, Germs and Steel and The Third Chimpanzee provides sociological and anthropological evidence for the rise of large scale warfare as a result of advances in technology and city-states. The rise of agriculture provided a significant increase in the number of individuals that a region could sustain over hunter-gatherer societies, allowing for development of specialized classes such as soldiers, or weapons manufacturers. On the other hand, tribal conflicts in hunter-gatherer societies tend to result in wholesale slaughter of the opposition (other than perhaps females of child-bearing years) instead of territorial conquest or slavery, presumably as hunter-gatherer numbers could not sustain empire-building. | [[Jared Diamond]] in his award-winning books, Guns, Germs and Steel and The Third Chimpanzee provides sociological and anthropological evidence for the rise of large scale warfare as a result of advances in technology and city-states.
