Know Your Constitution

The Document That Secures Our Liberty

A foundational primer on the constitutional principles that have safeguarded American self-government for more than two centuries.

Separation of Powers

Articles I, II, and III divide the federal government into three co-equal branches — Congress writes the laws, the President enforces them, and the courts interpret them. Each branch checks the others so that, in James Madison's words, “ambition must be made to counteract ambition.”

The Bill of Rights

Ratified in 1791, the first ten amendments guarantee the freedoms of speech, religion, and the press, the right to keep and bear arms, protection from unreasonable searches and seizures, and due process of law — rights the Framers considered essential safeguards against government overreach.

Federalism and the Tenth Amendment

The Constitution grants the federal government only specific, enumerated powers. The Tenth Amendment reserves everything else “to the States respectively, or to the people,” preserving local self-government as a check on federal authority.

The Rule of Law

Article VI makes the Constitution “the supreme Law of the Land,” binding on every official and citizen alike. No president, judge, or legislator stands above it — a principle the Framers saw as the foundation of ordered liberty.
