The Constitution in Plain Language

The short answer. The Constitution is mostly not a list of rights. It is a set of instructions for building a government: who gets which power, how they check each other, and what the government is forbidden to do. The rights everybody quotes are amendments added afterward. There are 27 of them in more than two centuries, because changing it is deliberately very hard.

Written in 1787, ratified in 1788, in effect since 1789. Seven articles and 27 amendments. It is short enough to read in an afternoon and most Americans never have.

The American Bar Association surveyed 1,000 residents in March 2025 and found 45 percent knew that “We the People” opens it, and 39 percent could correctly identify the Constitution, federal statutes and treaties as the supreme law of the land.

The Seven Articles, in Order

Article	What it does
I	Creates Congress and lists what it may do. The longest article by far, which tells you what the drafters thought the center of gravity would be.
II	Creates the presidency. Notably brief and vague, which is the source of a great many modern arguments.
III	Creates the Supreme Court and lets Congress create the rest of the federal courts.
IV	How the states relate to each other and to the federal government.
V	How to amend the document.
VI	The supremacy clause. Federal law made under the Constitution outranks conflicting state law.
VII	How it was originally ratified. Of historical interest only.

Notice what is missing from that list. No mention of political parties, which the drafters did not anticipate. No mention of a right to vote in the original text. No cabinet departments, no agencies, no primaries. Most of the government you interact with was built later, by statute, inside the space Article I left open.

The Bill of Rights

The first ten amendments, ratified together in 1791 as the price of getting the Constitution approved in the first place.

First. Religion, speech, press, assembly, and petitioning the government. Five rights, and in a 2025 Annenberg survey about nine percent of adults could name all five. Only 12 percent named petition, which is the one that underwrites every public comment and every letter to an official.
Second. Keeping and bearing arms.
Third. No quartering of soldiers in private homes. Effectively dormant.
Fourth. No unreasonable searches and seizures, and warrants require probable cause.
Fifth. Grand jury for serious federal charges, no double jeopardy, no compelled self incrimination, due process, and no taking of private property without just compensation.
Sixth. Speedy and public trial, an impartial jury, notice of the charges, confronting witnesses, and counsel.
Seventh. Jury trial in certain civil cases.
Eighth. No excessive bail or fines, no cruel and unusual punishment.
Ninth. Listing some rights does not mean those are the only ones people have.
Tenth. Powers not given to the federal government are reserved to the states or the people.

The Fourteenth Amendment, Which Changed Everything

Ratified in 1868 after the Civil War, and arguably the most consequential amendment in the document. Three things in one sentence structure.

Citizenship. It defines who is a citizen, including people born in the United States and subject to its jurisdiction.

Due process. No state may deprive any person of life, liberty or property without due process of law.

Equal protection. No state may deny to any person within its jurisdiction the equal protection of the laws.

Here is why it changed everything. The Bill of Rights originally restrained only the federal government. A state could, as a matter of federal constitutional law, do things the federal government could not. Through a long line of cases interpreting the Fourteenth Amendment, the Supreme Court applied most of the Bill of Rights to the states as well. That process is called incorporation, and it is the reason your local police are bound by the Fourth Amendment.

Person Versus Citizen, and Why the Wording Matters

This is the part that surprises people, and it is worth stating precisely because it is so often misstated in both directions.

Most constitutional protections are written to cover persons, not citizens. The Fifth and Fourteenth Amendments say “any person.” The Fourth Amendment says “the people.” The Sixth Amendment speaks of “the accused.” The Supreme Court has read these as reaching noncitizens within the United States. In Yick Wo v. Hopkins in 1886 the Court struck down the discriminatory enforcement of a San Francisco ordinance against Chinese laundry operators, holding that equal protection reaches all persons within a jurisdiction regardless of nationality. In Plyler v. Doe in 1982 the Court held that a state could not deny free public education to children present without lawful status.

A smaller set of rights is explicitly tied to citizenship. The amendments dealing with voting are phrased that way: the Fifteenth, Nineteenth, Twenty Fourth and Twenty Sixth all protect the right of “citizens” to vote from being denied on particular grounds. Certain federal offices carry citizenship requirements written into Articles I and II, and the presidency additionally requires being a natural born citizen.

So the accurate summary is this. The Constitution protects persons broadly and reserves the ballot and certain offices to citizens. Immigration law itself is separate, it is statutory, and it gives the federal government powers over admission and removal that do not fit neatly into any of the above.

Which rooms are open to you, and what happens in them

How It Gets Amended

Article V sets out the usual path: two-thirds of both chambers of Congress propose an amendment, then three fourths of the states must ratify it, which today means 38 states. There is a second path in which two-thirds of state legislatures call a convention, which has never been used to produce an amendment.

Twenty-seven amendments in more than two centuries, and ten of those arrived together in 1791. The difficulty is the design. It means the document does not move with an election, and it also means the meaning of unchanged text shifts through court interpretation instead, which is why Supreme Court appointments carry the weight they do.

What the Constitution Does Not Do

It mostly restrains government, not private parties. The First Amendment stops the government from punishing your speech. It does not require your employer, your landlord or a website to host it. Most claims that begin “that violates my First Amendment rights” against a private company are describing something other than a constitutional question.

It grants very few positive entitlements. It generally tells government what it may not do rather than what it must provide. Rights to education, health coverage and benefits come from statutes and from state constitutions, several of which do guarantee public education explicitly.

It is not self enforcing. A right becomes real through a court case, a statute, an agency rule or an official who follows it. That is why the rest of this site is about the machinery.

What changes for you

Knowing that the First Amendment protects petitioning the government tells you that writing to an agency during a comment period is not a favor you are asking. Knowing that equal protection and due process cover persons rather than only citizens matters if your family includes people at different stages of status. Knowing that your state constitution may guarantee things the federal one does not is often where an actual remedy lives. And knowing that the Constitution restrains government rather than neighbors saves a great deal of wasted argument.

Common Questions About the Constitution

How long is the Constitution?

About 4,500 words in its original form, which is short enough to read in under half an hour. With all twenty-seven amendments it runs to roughly 7,600 words. It is the oldest written national constitution still in use and among the shortest.

What are the three branches the Constitution creates?

Article I creates Congress, which writes law. Article II creates the presidency, which carries law out. Article III creates the federal courts, which decide what law means in an actual dispute. The order is deliberate: the framers put the lawmaking branch first and gave it the longest article.

How is the Constitution amended?

Two-thirds of both chambers of Congress propose an amendment, or two-thirds of state legislatures call a convention, which has never happened. Ratification then requires three quarters of the states, currently thirty-eight. Thousands of amendments have been proposed and twenty-seven have been adopted.

What is the Bill of Rights?

The first ten amendments, ratified together in 1791. Several states made ratification of the Constitution conditional on adding them. They limit what government may do to people, and with narrow exceptions they speak of persons and the people rather than of citizens.

Does the Constitution apply to state and local government?

Most of it does now, and it did not always. The Bill of Rights originally restrained only the federal government. Through the Fourteenth Amendment, ratified in 1868, the Supreme Court has applied nearly all of its protections against the states, which is why your city police are bound by the Fourth Amendment and your school board by the First.

What is judicial review and where is it in the Constitution?

Judicial review is the power of courts to strike down a law that conflicts with the Constitution. It is not written in the document. The Supreme Court established it in Marbury v. Madison in 1803, reasoning that a written constitution is not supreme if ordinary legislation can override it.

What is the supremacy clause?

Article VI, which makes the Constitution, federal laws made under it and treaties the supreme law of the land, binding on state judges. It is the provision that settles what happens when valid federal law and state law genuinely conflict.

Where can I read the Constitution at no cost?

The National Archives publishes the full text and high resolution images of the original. It costs nothing and requires no account. Reading the actual words, rather than descriptions of them, is one of the most useful hours a citizen can spend.
