Which American document was influenced by Montesquieu's ideas about separation of powers?

I think it's The United States Constitution

Explanation:

His ideas about separation of powers became the basis for the United States Constitution. Despite Montesquieu's belief in the principles of a democracy, he did not feel that all people were equal. Montesquieu approved of slavery.

Although he published other works as well, his most influential volume was The Spirit of the Laws (1748). The Founding Fathers, most especially James Madison, drew upon Montesquieu's theory of the separation of powers when drafting the Constitution.

Montesquieu's oft-cited contribution to political discourse is his theory on the separation of powers between the legislative, executive and judicial branches, which became the bedrock of the U.S. Constitution and the way the founders envisioned a plan that would divide and thus balance the powers of the new government.
