" The Iroquois Nation presumably understood the transformative power of war when they developed parallel systems of government that protected civilians from warriors and vice versa. Peacetime leaders, called sachems, were often chosen by women and had complete authority over the civil affairs of the tribe until war broke out. At that point war leaders took over, and their sole concern was the physical survival of the tribe. They were not concerned with justice or harmony or fairness, they were concerned only with defeating the enemy. If the enemy tried to negotiate an end to hostilities, however, it was the sachems, not the war leaders, who made the final decision. If the offer was accepted, the war leaders stepped down so that the sachems could resume leadership of the tribe. "
