Western civilization has been at war with tribalism for 3,000 years. And that war was brought to the New World by the English colonists. A very early point in American law Chief Justice John Marshall is asked to decide the status of Indian tribes. And what he does.

But it is still the most important doctrine in American constitutional law.
