I disagree vehemently with the assertion that the state is a modern invention. Humans have organised themselves into states for the vast majority of human history. The earliest examples of writing were state records. In fact, to my knowledge, there are no ancient civilisations who (1) have developed writing and (2) did not organise themselves into states. Ancient Egypt, Sumner and Mesopotamia, Ancient China—all of the earliest known civilisations in recorded history—had states, the basic function of which has remained unchanged throughout history. They had rulers or bodies that created laws, collected taxes, raised armies to maintain their power and fight other states, and enforced their laws on their subjects.

While the Great Law of Peace of the Iroquois Confederacy was certainly known to the writers of the US Constitution, we know for a fact what their inspirations were, without needing to speculate, because they produced a large body of essays defending and explaining their reasoning. These are the Federalist Papers. You may have heard of them. We know that the writers draw inspiration from primarily European sources, such as the English Bill of Rights, the operation of the Roman Republic and of Athenian democracy, and of documents like the Magna Carta.

“enlightenment ideas”, like democracy and such. This framing is very cynical, since the european upper class probably got those concepts from the native Americans which the US displaced/genocided.

What an absolutely bizarre idea.
