The United States Constitution is the supreme law of the United States. It sets out the structure of the federal government, divides authority between national and state institutions, protects certain rights, and provides the process for constitutional amendment.
The Constitution was drafted at the Philadelphia Convention in 1787, signed on 17 September 1787, and came into force after ratification by the required states. It replaced the Articles of Confederation with a stronger federal framework while retaining a system of divided powers.
Structure
The Constitution contains a preamble, seven original articles, and later amendments.
The seven articles cover:
- Congress and the legislative power.
- The presidency and the executive power.
- The federal judiciary.
- Relations between states.
- The amendment process.
- Federal supremacy, public debts, oaths, and the rule that no religious test is required for federal office.
- Ratification.
The National Archives describes the first three articles as establishing the legislative, executive, and judicial branches. That structure is linked with checks and balances, so that no single branch is meant to dominate the whole federal system.
Preamble
The preamble begins with "We the People". It introduces the purposes of the Constitution, including forming a more perfect union, establishing justice, providing for defence, promoting general welfare, and securing liberty.
The preamble is important symbolically because it frames the Constitution as an act of the people rather than a grant from a monarch, state legislature, or foreign authority. It does not itself create detailed powers, but it shapes how the document is understood.
Federal Government
Article I vests legislative power in Congress, made up of the Senate and the House of Representatives. Congress makes federal law, controls taxation and spending, confirms some appointments through the Senate, and has powers including declaring war.
Article II vests executive power in the President. The President executes federal law, commands the armed forces, appoints officers with Senate involvement where required, negotiates treaties subject to Senate consent, and performs other constitutional duties.
Article III creates the federal judiciary. It establishes the Supreme Court and allows Congress to create lower federal courts. Federal courts interpret federal law and decide cases within constitutional and statutory limits.
Federalism
The Constitution divides authority between the federal government and the states. Some powers are given to the federal government, some are denied to states, and others remain with the states or the people.
The Tenth Amendment expresses this principle by reserving powers not delegated to the United States, and not prohibited to the states, to the states or the people.
Federalism is not only a legal design. It affects elections, policing, criminal law, education, health policy, taxation, civil rights litigation, emergency powers, and disputes over state and federal authority.
Amendments
The Constitution has 27 amendments. The first ten amendments are known as the Bill of Rights. They protect rights including freedom of speech, religion, press, assembly, petition, protections against unreasonable searches, due process, trial rights, and limits on federal power.
Later amendments abolished slavery, defined birthright citizenship, addressed equal protection and due process, expanded voting rights, changed presidential elections and succession rules, allowed federal income tax, and limited presidents to two elected terms.
The amendment process is deliberately difficult. It usually requires proposal by two-thirds of both houses of Congress and ratification by three-quarters of the states.
Interpretation
Constitutional interpretation is a central part of American law and politics. Courts, Congress, the President, states, lawyers, scholars, and voters all contest what constitutional language means in practice.
Major interpretive approaches include originalism, textualism, structural reasoning, precedent-based interpretation, and living constitutionalism. The Supreme Court has final authority in cases before it, but constitutional meaning also develops through legislation, executive practice, state action, political conflict, and amendment.
Influence and Criticism
The United States Constitution is one of the world's oldest written national constitutions still in force. It has influenced constitutional design elsewhere, especially federalism, judicial review, separation of powers, written rights, and presidential systems.
It has also been criticised. Arguments focus on slavery in the founding settlement, unequal representation in the Senate, the Electoral College, difficulty of amendment, broad executive power, judicial appointment politics, and disputes over rights and state power.
