territory was the same; but the human beings had changed. Hence the division by territories was chosen as the point of departure, and citizens had to exercise their rights and duties wherever they chose their abode without regard to gens and tribe. This organization of inhabitants by localities is a common feature of all states. It seems natural to us now. But we have seen what long and hard fighting was required before it could take, in Athens and Rome, the place of the old organization by blood kinship.
In the second place, the state created a public power of coërcion that did no longer coincide with the old self-organized and armed population. This special power of coërcion is necessary, because a self-organized army of the people has become impossible since the division of society into classes took place. For the slaves belonged also to society. The 90,000 citizens of Athens formed only a privileged class compared to the 365,000 slaves. The popular army of the Athenian democracy was an aristocratic public power designed to keep the slaves down. But we have seen that a police force became also necessary to maintain order among the citizens. This public power of coërcion exists in every state. It is not composed of armed men alone, but has also such objects as prisons and correction houses attached to it, that were unknown to gentilism. It may be very small, almost infinitesimal, in societies with feebly developed class antagonisms and in out of the way places, as was once the case in certain regions of the United States. But it increases in the same ratio in which the class antagonisms become more pronounced, and in which neighboring states become larger and more populous. A conspicuous example is modern Europe, where the class struggles and wars of conquest have nursed the public power to such a size that it threatens to swallow the whole society and the state itself.
