The supreme law of the land: a short document — about 4,500 words — that builds a national government, divides its powers, and binds it to the people who created it.
of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
The framers wrote a framework, not a rulebook for daily life. Its power comes from a few durable ideas arranged in seven Articles.
The first three Articles create the three branches of government and give each its own job: Congress makes the laws, the President carries them out, and the courts interpret them. The remaining Articles handle the relationship between the states, how the document can be changed, what makes it supreme, and how it was to be ratified.
Two principles run through all of it. Separation of powers splits authority so no single branch can dominate, and checks and balances let each branch restrain the others — the President can veto laws, Congress can override vetoes and remove officials, and the courts can strike down acts that violate the Constitution. A third idea, federalism, divides power between the national government and the states.
Creates Congress, a two-house legislature: the House of Representatives (apportioned by population, elected every two years) and the Senate (two per state, six-year terms). It lists Congress’s powers — to tax, borrow, coin money, regulate commerce, declare war, and “make all Laws which shall be necessary and proper” to carry them out — and spells out limits on both Congress and the states. It is the longest Article, because the framers meant the elected legislature to be the government’s center of gravity.
Vests executive power in a President elected for four years through the Electoral College, alongside a Vice President. The President is Commander in Chief, makes treaties and appoints judges and officers (with the Senate’s advice and consent), and must “take Care that the Laws be faithfully executed.” This Article also provides that the President and other officers can be removed through impeachment for “Treason, Bribery, or other high Crimes and Misdemeanors.”
Establishes “one supreme Court” and lets Congress create the lower federal courts. Federal judges serve “during good Behaviour” — effectively for life — to keep them independent. It defines the reach of federal judicial power, guarantees jury trials in criminal cases, and carefully limits the crime of treason so it cannot be used against political enemies.
Governs how the states relate to one another and to the nation. States must give “Full Faith and Credit” to each other’s laws and court judgments, and treat one another’s citizens equally. It sets out how new states join the Union, gives Congress authority over federal territory, and guarantees every state “a Republican Form of Government” and protection against invasion.
Provides how the Constitution can be changed — deliberately difficult, but possible. An amendment may be proposed by a two-thirds vote of both houses of Congress (or by a convention called by two-thirds of the states) and becomes law only when ratified by three-fourths of the states. In more than two centuries this has happened just 27 times.
Declares the Constitution, and the federal laws and treaties made under it, “the supreme Law of the Land” — binding on judges in every state. It honors the debts the young nation had already taken on, requires officials to swear an oath to support the Constitution, and forbids any religious test for public office.
Sets the terms for putting the Constitution into effect: approval by conventions in nine of the thirteen states. New Hampshire became the decisive ninth state in June 1788, and the new government began the following year.
Congress — the House and the Senate — writes the laws, controls federal spending, and can declare war. It can override a veto and remove officials through impeachment.
The President enforces the laws, commands the military, conducts foreign policy, and appoints judges and officials — subject to the Senate’s approval and the courts’ review.
The Supreme Court and lower courts interpret the laws and the Constitution, and can strike down government actions that conflict with it — a power known as judicial review.
