1215
📜DocumentMagna Carta
King John of England signs Magna Carta, establishing that even the king is subject to the rule of law. Key clauses guarantee due process and prohibit arbitrary imprisonment.
Why it matters: The foundational document of Anglo-American constitutionalism. The phrase due process of law traces directly to Magna Carta.
1620
📜DocumentMayflower Compact
Before disembarking in Plymouth, the Pilgrims sign a self-governing compact, the first written framework of self-government in the New World.
Why it matters: Placeholder. The Compact demonstrated that legitimate government requires the consent of those governed, a principle that would anchor the Declaration 156 years later.
1689
💡PhilosophyEnglish Bill of Rights and Locke's Two Treatises
England's Glorious Revolution produces the English Bill of Rights. John Locke publishes his Two Treatises of Government, articulating natural rights theory that would directly shape the American founding.
Why it matters: Locke's argument that governments derive their just powers from the consent of the governed became the philosophical backbone of the Declaration of Independence.
1735
⚖️Court DecisionZenger Trial: Freedom of the Press
John Peter Zenger is acquitted of seditious libel after his lawyer argues that truth is a defense, establishing an early American precedent for press freedom.
Why it matters: Placeholder. The Zenger case planted seeds for what would become the First Amendment's press freedom guarantee.
1761
⚖️Court DecisionJames Otis Argues Against Writs of Assistance
Boston lawyer James Otis argues against British general search warrants, invoking natural law. John Adams later called this the moment the child independence was born.
Why it matters: Otis's argument directly inspired the Fourth Amendment's protection against unreasonable searches and seizures.
1765
⚔️ConflictStamp Act and Colonial Resistance
Britain imposes the Stamp Act, direct taxation without colonial representation. No taxation without representation becomes the rallying cry, and the Stamp Act Congress unites the colonies for the first time.
Why it matters: Placeholder. The Stamp Act crisis crystallized the constitutional argument that would lead to independence: a government may not tax those it does not represent.
1776
📜DocumentDeclaration of Independence
Thomas Jefferson drafts the Declaration, asserting that all men are created equal and endowed with unalienable Rights including Life, Liberty and the pursuit of Happiness.
Why it matters: The Declaration established the moral foundation of the American republic: natural rights, consent of the governed, and the right to alter or abolish destructive government.
1781
🏛️InstitutionArticles of Confederation Ratified
The first American constitution creates a weak central government with no power to tax, no executive, and no federal courts.
Why it matters: The Articles' failure demonstrated that limited government still requires sufficient power to function. This lesson directly shaped the Constitution's design.
1786
⚔️ConflictShays' Rebellion
Massachusetts farmers stage an armed uprising against the state government. The federal government is powerless to respond, exposing the fatal weakness of the Articles of Confederation.
Why it matters: Placeholder. Shays' Rebellion was the immediate catalyst for the Constitutional Convention, proving that a government without power to maintain order is no government at all.
1787
📜DocumentConstitutional Convention
Fifty-five delegates meet in Philadelphia and draft the Constitution, establishing three branches with separated powers, enumerated grants of authority, and federal supremacy.
Why it matters: The Constitution's architecture of enumerated powers, separation of powers, checks and balances, and federalism remains the framework of American government.
1787-1788
💡PhilosophyThe Federalist Papers
Hamilton, Madison, and Jay publish 85 essays defending the Constitution under the pen name Publius. They remain the most authoritative commentary on the Constitution's original meaning.
Why it matters: Federalist No. 10, 51, and 78 are still cited by the Supreme Court as evidence of the Constitution's original meaning.
1791
📜DocumentBill of Rights Ratified
The first ten amendments protect freedom of speech, press, religion, and assembly; the right to bear arms; protection from unreasonable search and seizure; due process; and rights retained by the people and states.
Why it matters: Many of the most contested constitutional debates today turn on these amendments.
1798
📉ErosionAlien and Sedition Acts
Congress criminalizes criticism of the government. Madison and Jefferson respond with the Virginia and Kentucky Resolutions. The Acts expire under political pressure in 1801.
Why it matters: Placeholder. The Sedition Acts crisis established the principle that political dissent is constitutionally protected, a principle the Supreme Court took 150 years to formally adopt.
1803
⚖️Court DecisionMarbury v. Madison
Chief Justice John Marshall establishes judicial review, the Supreme Court's authority to strike down laws that violate the Constitution.
Why it matters: Judicial review is the primary mechanism for enforcing constitutional limits. Without it, the Constitution's restraints would be aspirational rather than enforceable.
1819
⚖️Court DecisionMcCulloch v. Maryland
The Supreme Court upholds Congress's power to charter a national bank, establishing broad implied powers under the Necessary and Proper Clause.
Why it matters: Placeholder. McCulloch set the template for expansive federal power, shaping constitutional interpretation for two centuries.
1830
📉ErosionIndian Removal Act
Congress authorizes the forced relocation of Native American tribes. President Jackson defies the Supreme Court's ruling in Worcester v. Georgia protecting Cherokee sovereignty.
Why it matters: Placeholder. Jackson's defiance of the Supreme Court was among the most serious violations of the rule of law in early American history.
1857
📉ErosionDred Scott v. Sandford
The Supreme Court rules that Black Americans cannot be citizens and have no rights which the white man was bound to respect.
Why it matters: Placeholder. Dred Scott is widely considered the worst decision in Supreme Court history, a catastrophic failure of the rule of law that pushed the nation toward Civil War.
1863
📜DocumentEmancipation Proclamation and Gettysburg Address
Lincoln transforms the Civil War into a war for human freedom. At Gettysburg, he reframes the founding promise: a new birth of freedom dedicated to the proposition that all men are created equal.
Why it matters: Placeholder. Lincoln's Gettysburg Address is the most powerful restatement of founding values in American history.
1865-1870
📜DocumentReconstruction Amendments
The Thirteenth Amendment abolishes slavery (1865), the Fourteenth guarantees equal protection and due process (1868), and the Fifteenth protects Black men's right to vote (1870).
Why it matters: The Fourteenth Amendment became the constitutional vehicle for applying almost all of the Bill of Rights to state governments.
1873
📉ErosionSlaughter-House Cases: Privileges or Immunities Gutted
The Supreme Court's first interpretation of the Fourteenth Amendment effectively reads the Privileges or Immunities Clause out of the Constitution.
Why it matters: Placeholder. By gutting Privileges or Immunities, the Court crippled the Fourteenth Amendment just five years after ratification, a decision Justice Thomas has long argued should be revisited.
1896
📉ErosionPlessy v. Ferguson: Separate but Equal
The Supreme Court upholds racial segregation under the doctrine of separate but equal, gutting the Reconstruction Amendments' promise of equality for the next 58 years.
Why it matters: Placeholder. Plessy represents the ultimate betrayal of Reconstruction, the Court ratifying the Jim Crow system that replaced slavery with a new architecture of racial subordination.
1905
⚖️Court DecisionLochner v. New York
The Supreme Court strikes down a New York law limiting bakers' working hours, holding that freedom of contract is a protected liberty.
Why it matters: Placeholder. Lochner is controversial: conservatives see it as legitimate protection of economic liberty; progressives as judicial activism. Its repudiation in 1937 opened the door to unlimited economic regulation.
1913
🏛️InstitutionIncome Tax, Federal Reserve, and Direct Senate Elections
The Sixteenth Amendment authorizes the income tax, the Seventeenth requires direct election of senators, and Congress creates the Federal Reserve, reshaping the federal-state balance.
Why it matters: The Seventeenth Amendment removed an important check on federal power by breaking the link between state legislatures and Senate representation.
1917-1918
📉ErosionEspionage and Sedition Acts: WWI Speech Suppression
Congress criminalizes anti-war speech during World War I. The Supreme Court upholds these convictions, producing Holmes's clear and present danger standard.
Why it matters: Placeholder. The WWI speech cases were the Court's first serious engagement with First Amendment limits. Holmes's later dissents laid the groundwork for modern free speech doctrine.
1937
📉ErosionThe New Deal Court Revolution
After FDR's court-packing threat, the Supreme Court abandons its resistance to New Deal legislation, dramatically expanding federal power and ending meaningful judicial review of economic regulation.
Why it matters: The switch in time that saved nine marked the end of the era in which courts actively policed the limits of congressional power. The administrative state expanded rapidly.
1944
📉ErosionKorematsu v. United States
The Supreme Court upholds the internment of 120,000 Japanese Americans without charges or trial, deferring to military necessity during World War II.
Why it matters: Placeholder. Korematsu is now universally condemned as proof that constitutional democracies can betray their own values under pressure.
1954
⚖️Court DecisionBrown v. Board of Education
A unanimous Supreme Court strikes down school segregation, overruling Plessy v. Ferguson and holding that separate educational facilities are inherently unequal.
Why it matters: Placeholder. Brown is the most celebrated Supreme Court decision of the 20th century, the Court finally making good on the Fourteenth Amendment's 86-year-old promise.
1964-1965
✊ProgressCivil Rights Act and Voting Rights Act
Congress prohibits discrimination based on race, color, religion, sex, or national origin (1964) and protects Black Americans' voting rights (1965).
Why it matters: These laws represent the most significant fulfillment of the Fourteenth Amendment's equal protection guarantee since Reconstruction.
1965
⚖️Court DecisionGriswold v. Connecticut: Right to Privacy
The Supreme Court strikes down a Connecticut law banning contraception, discovering a constitutional right to privacy in the penumbras of the Bill of Rights.
Why it matters: Placeholder. Griswold launched the modern constitutional privacy doctrine. Originalists question whether the Constitution contains such a right.
1966
⚖️Court DecisionMiranda v. Arizona
The Supreme Court requires police to inform suspects of their constitutional rights before interrogation, producing the now-iconic Miranda warning.
Why it matters: Placeholder. Miranda extended Fifth and Sixth Amendment protections into the police station, ensuring the right against self-incrimination is meaningful in practice.
1973
⚖️Court DecisionRoe v. Wade
The Supreme Court holds that the Constitution protects a right to abortion, striking down abortion laws in all 50 states. The decision becomes the most contested in modern constitutional law.
Why it matters: Placeholder. Roe, later overruled by Dobbs in 2022, exemplified living constitutionalism: the Court reading new rights into the Constitution based on evolving values.
1984
📉ErosionChevron Deference: Agencies Interpret Their Own Power
The Supreme Court holds that courts must defer to federal agencies' reasonable interpretations of ambiguous statutes, giving agencies enormous power to define their own authority.
Why it matters: Placeholder. Chevron became the legal foundation of the administrative state, allowing the executive branch to effectively legislate. The Court began correcting this in Loper Bright (2024).
1991
🏛️InstitutionClarence Thomas Joins the Supreme Court
Following a contentious confirmation hearing, Clarence Thomas joins the Supreme Court. He would go on to become its most consistent originalist voice over the following decades.
Why it matters: Thomas's jurisprudence, insisting on original public meaning and skeptical of administrative deference, represents the most sustained effort to return constitutional interpretation to founding-era foundations.
1995
⚖️Court DecisionUnited States v. Lopez: Commerce Clause Limits Restored
For the first time since 1937, the Supreme Court strikes down a federal law as exceeding Congress's Commerce Clause power, signaling a revival of constitutional limits.
Why it matters: Placeholder. Lopez was a landmark victory for limited government constitutionalism. After 58 years, the Court said: Congress has gone too far.
2008
⚖️Court DecisionHeller: Second Amendment as Individual Right
The Supreme Court holds that the Second Amendment guarantees an individual right to keep and bear arms for self-defense, unconnected to militia service.
Why it matters: Placeholder. Heller was one of the most significant originalist victories in constitutional history, establishing that the Second Amendment means what it says.
2010
⚖️Court DecisionCitizens United: Political Speech and the First Amendment
The Supreme Court strikes down limits on corporate and union independent political expenditures, holding that political speech does not lose First Amendment protection because its source is a corporation.
Why it matters: Placeholder. Citizens United turned on the foundational question: does the First Amendment protect speech based on its content, or its speaker?
2022
⚖️Court DecisionBruen: Originalism Becomes the Court's Dominant Method
Justice Thomas writes the majority opinion in NYSRPA v. Bruen, establishing that firearm regulations must be evaluated against historical tradition at the founding.
Why it matters: Bruen signaled that originalism is no longer a dissenting voice on the Supreme Court but the dominant methodology.
2022
⚖️Court DecisionDobbs v. Jackson: Roe Overruled
The Supreme Court overrules Roe v. Wade, holding that the Constitution does not confer a right to abortion and returning the question to state legislatures.
Why it matters: Placeholder. Dobbs is the most consequential application of originalism in the Court's history, a genuine return to the principle that the Constitution's meaning is fixed by its text and history.
2024
⚖️Court DecisionLoper Bright: Chevron Deference Overruled
The Supreme Court overrules the 40-year-old Chevron doctrine, holding that courts, not agencies, must interpret statutes. The most significant check on administrative state power in a generation.
Why it matters: Placeholder. Loper Bright restores judicial independence in statutory interpretation, taking a major step toward the founders' separation of powers.
2026
⭐MilestoneThe 250th Anniversary
The United States marks 250 years since the Declaration of Independence. The occasion invites reflection on how faithfully the nation has preserved the founding values of liberty, limited government, and the rule of law.
Why it matters: The semiquincentennial is not merely a celebration but a reckoning. The founding values are not self-executing. Each generation must understand, defend, and transmit them anew.
