In the Norte Chico, Haas told me, government seems not to have arisen from the need for mutual defense, as philosophers have often speculated. The twenty-five cities were not sited strategically and did not have defensive walls; no evidence of warfare, such as burned buildings or mutilated corpses, has been found. Instead, he said, the basis of the rulers’ power was the collective economic and spiritual good. Norte Chico was the realm of King Cotton.
