What are some ideas of the enlightenment influenced the constitution?

The Enlightenment introduced ideas such as individual rights, the social contract, and separation of powers, which significantly influenced the U.S. Constitution. Thinkers like John Locke emphasized the importance of natural rights, which is reflected in the Declaration of Independence and the Constitution's Bill of Rights. Montesquieu's concept of separating governmental powers into distinct branches—executive, legislative, and judicial—ensured a system of checks and balances to prevent tyranny. These Enlightenment principles laid the foundation for a democratic government that prioritizes liberty and justice.
