The U.S. Constitution: course overview

The U.S. Constitution is about 4,500 words in its original form plus 27 amendments. This course goes through all of it: the Preamble, all seven articles section by section, and every amendment. Each lesson shows the official National Archives text, explains it clause by clause, gives the history, shows how courts read it with linked cases, and says what it means for a city like Williams Verified1,2,3.

How each lesson is built

Every lesson follows the same order, so you always know where to look. Short lessons skip a step when there's nothing to say:

1. Official text. Shown in a shaded quote box, word for word from the National Archives transcription, with a link to the same spot on our full-text page. Old text that a later amendment changed gets a Changed. note right after the quote, using the Archives' own wording Verified3.
2. History. Why it's there, checked against the Library of Congress's Constitution Annotated.
3. Clause by clause. What each sentence does, in plain English. Long articles go section by section instead.
4. How courts read it. Supreme Court cases, each linked to the full opinion. Quotes from cases were machine-checked against the opinion text.
5. How it reaches Williams. Whether the clause binds only the federal government or also California and its cities, and how.
6. In Williams. Where the clause touches city government: code enforcement, inspections, fines, fees, property, speech at council meetings, and public records.
7. Common misconceptions, stated bluntly.
8. Check yourself. Short questions with hidden answers.

Three rules for reading the Constitution

1. It is mostly about the federal government. Articles I, II and III build Congress, the President and the federal courts. The Bill of Rights, as written, limited only the federal government. The Supreme Court said so in 1833: the first ten amendments "contain no expression indicating an intention to apply them to the State governments" (Barron v. Baltimore) Verified4. Most of it reaches Williams today only through the Fourteenth Amendment. See Amendment 14 and Incorporation.

2. A city is part of the state. For constitutional purposes, the City of Williams counts as the State of California acting locally. When the Fourteenth Amendment says "No State shall," it means the City Council, the city manager and a code enforcement officer too. See State law and the city.

3. The text is the start, not the end. Courts have read every clause for more than two centuries. A phrase like "unreasonable searches and seizures" means what the cases say it means. That's why each lesson pairs the text with cases, and why this course never calls a Williams rule unconstitutional as settled fact. Only a court can decide that.

The lessons

The Preamble and the seven articles

1. The Preamble: who creates the government, and why — "We the People": what the opening sentence does, and why courts say it grants no power.
2. Article I, Sections 1–7: How Congress is built and how a bill becomes law — The House, the Senate, elections, rules, pay, and the path from bill to law.
3. Article I, Section 8: The powers of Congress — All 18 clauses: taxing and spending, commerce, money, war, and the Necessary and Proper Clause.
4. Article I, Sections 9–10: What Congress and the states may not do — Habeas corpus, bills of attainder, ex post facto laws, the Contracts Clause, and other limits that bind cities too.
5. Article II: The President and the executive branch — How the President is chosen, what the office can do, and the limits courts have set.
6. Article III: The federal courts — Judicial power, life tenure, cases and controversies, standing, jury trials and treason.
7. Article IV: How the states treat each other — Full faith and credit, privileges and immunities, extradition, new states, federal land, and the Guarantee Clause.
8. Article V: How the Constitution is amended — The two ways to propose and two ways to ratify an amendment, and why it's so hard.
9. Article VI: The supreme law of the land — Old debts, the Supremacy Clause, the oath, and the ban on religious tests for office.
10. Article VII: Ratification, and how the Constitution took effect — Nine state conventions, the signing, why ratification by the people mattered, and how California voters still ratify their own constitution's changes.

The Bill of Rights (Amendments 1–10)

1. First Amendment: Religion, speech, press, assembly and petition — Five freedoms in 45 words, and the tests courts use when a city regulates signs, protests, prayer or public comment.
2. Second Amendment: The right to keep and bear arms — An individual right, applied to states and cities, judged by history and tradition since 2022.
3. Third Amendment: No quartering of soldiers — The least-litigated amendment, and why it still matters as a statement about the privacy of the home.
4. Fourth Amendment: Searches, seizures and warrants — When police or city inspectors need a warrant, what counts as a search, and what happens when the rule is broken.
5. Fifth Amendment: Grand juries, double jeopardy, self-incrimination, due process and takings — Five protections in one sentence, including the Takings Clause that governs every city permit condition and fee.
6. Sixth Amendment: Rights of the accused at trial — Speedy and public trial, an impartial jury, notice of the charge, confronting witnesses, and a lawyer.
7. Seventh Amendment: Civil jury trial — Jury trial in federal civil suits at common law. Not applied to the states, but California guarantees its own.
8. Eighth Amendment: Bail, fines and punishment — No excessive bail, no excessive fines, no cruel and unusual punishment, and why the fines clause reaches city code penalties.
9. Ninth Amendment: Rights not listed are still rights — Why the Bill of Rights isn't a complete list, why courts rarely enforce the Ninth Amendment on its own, and why California spells out rights like privacy instead.
10. Tenth Amendment: Powers reserved to the states and the people — Federalism in one sentence: where cities fit, what states keep, and the anti-commandeering rule.

Amendments 11–27

1. Eleventh Amendment: Suits against states — Why you can't usually sue California for money in federal court, and why you can sue Williams.
2. Twelfth Amendment: Separate electoral votes for President and Vice President — Why electors cast separate votes for President and Vice President, and what happens when no one wins a majority.
3. Thirteenth Amendment: Abolition of slavery — Slavery and involuntary servitude banned everywhere, with one exception for punishment of crime, plus Congress's power to end its badges and incidents.
4. Fourteenth Amendment: Citizenship, due process and equal protection — The amendment that makes the Bill of Rights bind Williams, plus the due process and equal protection rules behind most local disputes.
5. Fifteenth Amendment: No race discrimination in voting — No government may deny the vote on account of race, color or previous servitude, including city elections and city boundaries.
6. Sixteenth Amendment: Federal income tax — Lets Congress tax incomes without dividing the tax among the states by population; why it was needed, what counts as income, and why Williams can't have a city income tax.
7. Seventeenth Amendment: Popular election of senators — Voters, not state legislatures, elect U.S. senators; governors can fill vacancies temporarily. Why it changed, and how vacancies work for Senate seats and Williams council seats.
8. Eighteenth Amendment: Prohibition (repealed) — Banned making, selling and transporting alcohol nationwide from 1920 until its 1933 repeal; the only amendment ever repealed, and the source of two lasting rules about how amendments are ratified.
9. Nineteenth Amendment: Women's right to vote — Bars denying the vote on account of sex; how two California lawmakers figure in its history, why the Fourteenth Amendment wasn't enough, and what it guarantees in Williams elections.
10. Twentieth Amendment: Terms begin in January — Moved the start of presidential and congressional terms from March to January, shortening the lame-duck period, and fixed what happens if a President-elect dies or isn't chosen. Plus: when newly elected Williams council members take office.
11. Twenty-first Amendment: Repeal of Prohibition — Ended Prohibition, left alcohol regulation to the states, and was the only amendment ratified by state conventions.
12. Twenty-second Amendment: Presidential term limits — No one can be elected President more than twice. What it does and doesn't cover, how term limits work for California legislators, and how a city like Williams could adopt council term limits.
13. Twenty-third Amendment: Electoral votes for Washington, D.C. — Gives the District of Columbia presidential electors, capped at the number of the least populous state, and nothing more.
14. Twenty-fourth Amendment: No poll taxes in federal elections — Bans poll taxes in federal elections; Harper v. Virginia extended the ban to state and local elections under equal protection.
15. Twenty-fifth Amendment: Presidential succession and disability — What happens when a President dies, resigns, is disabled or can't serve, and how a Vice President vacancy is filled; how each part has been used; and how California and Williams fill the same kinds of gaps.
16. Twenty-sixth Amendment: Voting at 18 — Citizens 18 and older can't be denied the vote on account of age, in any election. How it passed so fast, a California Supreme Court case on student and young-adult voters, and how young people in Williams register.
17. Twenty-seventh Amendment: Congressional pay — A change in congressional pay can't take effect until after the next House election. Proposed in 1789, ratified in 1992, and echoed in California's rules for city council pay.

Where the text comes from

The text is the National Archives transcription of the Constitution Verified1, the Bill of Rights Verified2 and Amendments 11–27 Verified3. The Archives keeps the original spelling ("defence," "chuse") and capitalization. History is checked against the Constitution Annotated, the Library of Congress's official legal treatise on the Constitution, which we read on the Cornell LII copy Verified5. Case quotes come from the full opinions on Cornell's Legal Information Institute.
