American History

Colonial Era (1607–1763)

• John Peter Zenger trial (1735) — New York printer John Peter Zenger acquitted of seditious libel after his lawyer Andrew Hamilton argued truth as a defense; established an early precedent for freedom of the press in the colonies.
• Jamestown (1607) — first permanent English settlement in North America; founded by the Virginia Company in present-day Virginia; nearly failed; tobacco cultivation (introduced by John Rolfe) saved the colony.
• Pocahontas (c. 1596–1617) — daughter of Powhatan, the paramount chief of the Algonquian-speaking Confederacy in the Tidewater Virginia region; the story of her saving John Smith’s life (c. 1607) is recorded by Smith but is debated by historians; she was captured by English colonists (1613), converted to Christianity, took the name Rebecca, and married tobacco planter John Rolfe (1614); traveled to London as a symbol of colonial relations and died there in 1617; her son Thomas Rolfe was an ancestor of many Virginians.
• Pequot War (1636–1638) — one of the earliest and most violent conflicts between English colonists and Native Americans in New England; the Pequot tribe of southern Connecticut was targeted by Massachusetts Bay and Plymouth colonies and their Narragansett and Mohegan allies; the Mystic Massacre (May 1637) saw English and allied forces burn a Pequot village and kill approximately 400–700 people, mostly women, children, and elderly; the war ended the Pequot as an independent political force and opened Connecticut to English settlement.
• Plymouth Colony (1620) — Separatist Pilgrims arrived on the Mayflower; signed the Mayflower Compact, an early model of self-governance; made peace with the Wampanoag, associated with Massasoit.
• Massachusetts Bay Colony (1630) — Puritan settlement led by John Winthrop; “city upon a hill” rhetoric; established the General Court (legislature).
• Roger Williams — expelled from Massachusetts Bay; founded Providence (1636) in Rhode Island; early advocate for separation of church and state and Native American rights.
• Anne Hutchinson — antinomian controversy; banished from Massachusetts Bay (1638); settled in Rhode Island and later New York.
• Thirteen original colonies — founded throughout the 17th–18th centuries; by 1733 the original thirteen were established. Divided into New England (Mass., Conn., R.I., N.H.), Middle (N.Y., N.J., Pa., Del.), and Southern (Md., Va., N.C., S.C., Ga.) colonies.
• King Philip’s War (1675–1676) — Wampanoag chief Metacom (called “King Philip” by colonists) led a coalition of tribes against New England settlements; one of the deadliest per-capita conflicts in American history; ended with Metacom’s death and the collapse of Native resistance in southern New England.
• Bacon’s Rebellion (1676) — armed uprising in Virginia led by Nathaniel Bacon against Governor William Berkeley; grievances over frontier defense and power; significant because it shifted Virginia planters toward enslaved African labor to reduce reliance on indentured servants.
• Salem Witch Trials (1692) — mass hysteria in Salem, Massachusetts; approximately 20 executed after accusations of witchcraft; led by a special court; eventually discredited; later viewed as a cautionary tale about collective hysteria and the abuse of judicial authority.
• Great Awakening (c. 1730s–1740s) — religious revival sweeping the colonies; key preachers Jonathan Edwards (“Sinners in the Hands of an Angry God”) and George Whitefield (open-air itinerant preacher who drew enormous crowds); democratized religion and fostered a shared colonial identity that prefigured revolutionary sentiment.
• Albany Plan of Union (1754) — proposed by Benjamin Franklin at the Albany Congress; would have created an inter-colonial government to coordinate defense against the French; rejected by both the colonies and the Crown; seen as a forerunner of the Constitutional Convention.
• Salutary neglect — British policy (especially under Walpole) of loosely enforcing colonial trade laws; ended after the French and Indian War, fueling colonial resistance.
• French and Indian War (1754–1763) — North American theater of the Seven Years’ War; Britain and its colonies vs. France and allied Native nations; young George Washington fought at Fort Necessity (1754); British general Braddock defeated near Fort Duquesne (1755); General Wolfe’s capture of Quebec (1759) proved decisive; ended with the Treaty of Paris (1763), giving Britain Canada and territory east of the Mississippi.
• Proclamation of 1763 — British decree forbidding colonial settlement west of the Appalachians; angered colonists who had fought in the war expecting western land.

The American Revolution (1763–1783)

Causes and escalation

• Navigation Acts / mercantilism — pre-existing trade restrictions; tightened enforcement after 1763 triggered colonial protest.
• Stamp Act (1765) — first direct internal tax on colonists; “No taxation without representation”; Stamp Act Congress met in New York; repealed 1766 after the Stamp Act Congress and economic boycotts; Parliament simultaneously passed the Declaratory Act asserting full legislative authority over the colonies.
• Townshend Acts (1767) — taxes on imported goods (glass, tea, paper); imposed by Charles Townshend; partial repeal 1770; led to the Boston Non-Importation Agreement.
• Sons of Liberty — colonial resistance organization; Samuel Adams a key organizer in Boston; chapters in multiple colonies; coordinated protests, boycotts, and direct action against British taxation; operated through Committees of Correspondence.
• Boston Massacre (1770) — British soldiers killed five colonists during a crowd confrontation; victims included Crispus Attucks; publicized by Paul Revere’s engraving; inflamed colonial opinion; soldiers defended by John Adams at trial, most acquitted.
• Boston Tea Party (1773) — Sons of Liberty, including Samuel Adams, dumped 342 chests of British East India Company tea into Boston Harbor protesting the Tea Act.
• Intolerable Acts (1774) — also called the Coercive Acts; punitive British response to the Tea Party; closed Boston Harbor, revoked Massachusetts self-governance, expanded the Quartering Act; drove colonies toward the First Continental Congress.
• First Continental Congress (1774) — delegates from twelve colonies coordinated trade boycotts; agreed to reconvene.
• Lexington and Concord (April 1775) — first military engagements; “the shot heard round the world”; Paul Revere’s midnight ride warned colonists of British march.

Key figures and documents

• Thomas Paine, Common Sense (January 1776) — pamphlet arguing for independence in plain language; broad popular impact.
• Declaration of Independence (July 4, 1776) — drafted primarily by Thomas Jefferson; adopted by the Second Continental Congress; asserted natural rights (life, liberty, pursuit of happiness) derived from Locke; listed grievances against George III.
• George Washington — Commander-in-Chief of the Continental Army; key victories at Trenton (December 1776) and Yorktown (1781).
• Valley Forge (1777–1778) — harsh winter encampment; Continental Army survived with help from Friedrich von Steuben (training) and Marquis de Lafayette (morale and later aid).
• Saratoga (1777) — American victory over General Burgoyne; persuaded France to ally with the United States.
• Yorktown (1781) — final major battle; Cornwallis surrendered to Washington (aided by French fleet and troops under Rochambeau).
• Treaty of Paris (1783) — formally ended the war; Britain recognized U.S. independence; U.S. boundaries set at the Mississippi River to the west, Canada to the north, Florida to the south.

Founding and Early Republic (1783–1820)

• Articles of Confederation (1781–1789) — first U.S. governing document; weak central government; no power to tax or regulate commerce; Shays’ Rebellion (1786) exposed its failures.
• Shays’ Rebellion (1786–1787) — Massachusetts farmers led by Daniel Shays rose against debt and tax collection; state militia suppressed it; alarmed nationalists such as Washington and Hamilton into convening the Constitutional Convention to create a stronger central government.
• Constitutional Convention (1787) — Philadelphia; delegates including Madison, Hamilton, Franklin, Washington; produced the Constitution. Key compromises: Connecticut Compromise (bicameral legislature), Three-Fifths Compromise (enslaved persons counted as three-fifths for apportionment), Electoral College.
• Federalists vs. Anti-Federalists — Federalists (Hamilton, Madison, Jay) favored ratification; Anti-Federalists (Patrick Henry, George Mason) feared tyranny; Anti-Federalist demand for a bill of rights ultimately succeeded.
• Federalist Papers (1787–1788) — 85 essays by Hamilton, Madison, and Jay arguing for ratification; Federalist No. 10 (factions) and No. 51 (checks and balances) are most cited.
• Bill of Rights (1791) — first ten amendments; guarantees of speech, religion, press (1st), arms (2nd), against unreasonable search (4th), self-incrimination (5th), speedy trial (6th), and reserved powers (9th, 10th).
• Hamilton’s financial program — Secretary of the Treasury Alexander Hamilton proposed assumption of state debts, a national bank (the First Bank of the United States), and protective tariffs; Jefferson and Madison opposed it as unconstitutional; the compromise that placed the national capital on the Potomac broke the legislative deadlock; laid the foundation of the Federalist/Democratic-Republican split.
• Whiskey Rebellion (1794) — Pennsylvania farmers rebelled against Hamilton’s excise tax on whiskey; Washington personally led federal militia to suppress it; first major test of federal authority under the new Constitution; demonstrated the government could enforce its laws.
• XYZ Affair (1797–1798) — French agents (X, Y, Z) demanded a bribe before diplomatic negotiations with the Adams administration; when the correspondence was published, it outraged Americans; led to an undeclared Quasi-War with France at sea and nearly a full-scale war.
• Alien and Sedition Acts (1798) — passed under John Adams; restricted immigration and criticism of the government; Virginia and Kentucky Resolutions (Jefferson and Madison) asserted states’ right to nullify federal law; these resolutions later became a touchstone for states’ rights arguments.
• Election of 1800 — “Revolution of 1800”; Jefferson defeated Adams in a bitter contest; marked the first peaceful transfer of power between opposing parties in U.S. history; a tie in the Electoral College (Jefferson–Burr) sent the election to the House, where Hamilton’s support for Jefferson proved decisive.
• Marshall Court — Chief Justice John Marshall (1801–1835) shaped the federal judiciary; key decisions: Marbury v. Madison (1803, judicial review), McCulloch v. Maryland (1819, implied powers, federal supremacy), Gibbons v. Ogden (1824, broad commerce clause); established the Supreme Court as a co-equal branch.
• Marbury v. Madison (1803) — Chief Justice John Marshall established judicial review; landmark in constitutional law.
• Louisiana Purchase (1803) — Napoleon sold the Louisiana Territory to the U.S. for ~$15 million; doubled the nation’s size; Lewis and Clark Expedition (1804–1806) explored the new territory.
• War of 1812 (1812–1815) — conflict with Britain over impressment and frontier grievances; British burned Washington, D.C. (1814); Battle of New Orleans (Jackson’s victory, January 1815, fought after the peace treaty was signed); ended with the Treaty of Ghent.
• Era of Good Feelings (1817–1825) — period of relative political unity following the War of 1812 under President James Monroe; the Federalist Party had collapsed; one-party politics masked growing sectional tensions; the Missouri Crisis of 1819–1820 foreshadowed future conflict.
• American System — economic program championed by Senator Henry Clay of Kentucky; three components: protective tariffs to nurture domestic manufacturing, a national bank to provide stable currency and credit, and federal funding of internal improvements (roads, canals); opposed by strict constructionists and Southern agrarians; a major organizing principle of the Whig Party.
• Monroe Doctrine (1823) — declared the Western Hemisphere closed to further European colonization and that European intervention in the Americas would be considered a hostile act against the U.S.; largely symbolic at first (enforced by British naval power); became a cornerstone of U.S. foreign policy.
• Missouri Compromise (1820) — admitted Missouri as a slave state, Maine as a free state; banned slavery north of the 36°30’ line in the Louisiana Territory; authored by Henry Clay; Thomas Jefferson called it “a fire bell in the night.”

Expansion and Sectionalism (1820–1860)

• Nullification Crisis (1832–1833) — South Carolina, led by John C. Calhoun, declared federal tariffs of 1828 (“Tariff of Abominations”) and 1832 null and void within the state; President Jackson threatened military force and pushed a Force Bill through Congress; crisis resolved through a compromise tariff engineered by Henry Clay; established federal supremacy while also demonstrating sectional tensions over the tariff and states’ rights.
• Bank War (1832–1836) — Andrew Jackson vetoed the recharter of the Second Bank of the United States, calling it a monster of privilege; directed Treasury to withdraw federal deposits and place them in “pet banks”; Nicholas Biddle, the Bank’s president, contracted credit, causing a brief recession; Jackson’s destruction of the Bank contributed to the Panic of 1837.
• Andrew Jackson / Jacksonian Democracy — expanded voting rights for white men; championed “the common man”; spoils system (rotation in office); destroyed the Second Bank; Kitchen Cabinet of informal advisers; opposed nullification but also championed states’ rights against federal internal improvements.
• Spoils system — practice of rewarding political supporters with government jobs; Jackson systematized it under the principle of “rotation in office,” arguing it democratized government; critics saw it as corruption; later targeted by Pendleton Civil Service Act (1883).
• Indian Removal Act (1830) / Trail of Tears (1838–1839) — forced relocation of the Five Civilized Tribes (Cherokee, Creek, Choctaw, Chickasaw, Seminole) to Indian Territory (present-day Oklahoma); Supreme Court ruled in favor of Cherokee in Worcester v. Georgia (1832) but Jackson refused to enforce it; approximately 4,000–8,000 Cherokee died during the Cherokee removal.
• Second Great Awakening (c. 1790s–1840s) — wave of Protestant revivals; camp meetings on the frontier; Charles Grandison Finney a leading revivalist in the “burned-over district” of upstate New York; fueled reform movements including temperance, abolition, and women’s rights.
• Abolitionism — William Lloyd Garrison founded The Liberator (1831) and the American Anti-Slavery Society (1833); Frederick Douglass, escaped slave, became the movement’s most prominent Black voice, publishing Narrative of the Life of Frederick Douglass (1845) and the North Star newspaper; Harriet Beecher Stowe’s Uncle Tom’s Cabin (1852) galvanized Northern antislavery opinion; John Brown used violent methods.
• Whig Party (1833–1854) — formed in opposition to Jackson’s perceived executive tyranny; supported the American System; elected presidents William Henry Harrison (1840) and Zachary Taylor (1848); collapsed over slavery after the Compromise of 1850; succeeded by the Republican Party.
• Know-Nothing Party (American Party, c. 1850s) — nativist, anti-Catholic, anti-immigrant political movement; flourished briefly amid Whig collapse; secret fraternal origins (members told to say they “know nothing”); won several governorships and congressional seats; collapsed by 1856 as slavery overshadowed nativism.
• Free Soil Party (1848–1854) — opposed the expansion of slavery into the territories, primarily on grounds that free white labor would be degraded; “Free Soil, Free Speech, Free Labor, Free Men”; ran former president Martin Van Buren in 1848; absorbed into the Republican Party.
• Manifest Destiny — belief that U.S. expansion across the continent was inevitable and divinely sanctioned; coined by journalist John L. O’Sullivan (1845).
• Texas Annexation (1845) — Texas admitted as a state after earlier independence from Mexico (1836, Battle of the Alamo, San Jacinto).
• Mexican-American War (1846–1848) — sparked by disputed Texas boundary; ended with the Treaty of Guadalupe Hidalgo, ceding California, New Mexico, Arizona, and other territory; paid $15 million; Wilmot Proviso (1846), attempting to ban slavery in acquired territories, passed the House but failed in the Senate.
• Seneca Falls Convention (1848) — first major women’s rights convention; Stanton and Mott organized; “Declaration of Sentiments” modeled on the Declaration of Independence; demanded women’s suffrage.
• Compromise of 1850 — admitted California as free state; strengthened Fugitive Slave Act; abolished slave trade (not slavery) in D.C.; popular sovereignty for new territories; proposed by Henry Clay, brokered by Stephen Douglas; Daniel Webster’s support cost him Northern antislavery backing.
• Harriet Tubman and the Underground Railroad — Tubman escaped slavery in Maryland (1849) and made approximately 13 missions to rescue around 70 enslaved people; the Underground Railroad was a network of safe houses and conductors guiding enslaved people to freedom in the North and Canada.
• Kansas-Nebraska Act (1854) — replaced the Missouri Compromise line with popular sovereignty; led to “Bleeding Kansas” (pro- and anti-slavery violence, including John Brown’s Pottawatomie massacre); gave rise to the Republican Party.
• Lincoln-Douglas Debates (1858) — seven debates between Abraham Lincoln (Republican) and Stephen Douglas (Democrat) for the Illinois Senate seat; Douglas articulated the “Freeport Doctrine” (territories could effectively exclude slavery despite Dred Scott); Lincoln gained national prominence despite losing the Senate race.
• Dred Scott v. Sandford (1857) — Supreme Court (Chief Justice Taney) ruled enslaved people were not citizens and Congress could not prohibit slavery in territories; declared the Missouri Compromise unconstitutional; intensified sectional crisis and inflamed Republicans.
• John Brown’s Raid on Harpers Ferry (1859) — attempted to seize the federal arsenal and incite enslaved insurrection; captured by Robert E. Lee’s marines; tried and hanged; Brown was celebrated as a martyr in the North and terrified the South.
• Election of 1860 — Lincoln won with no Southern electoral votes; four-way race (Lincoln, Douglas, Breckinridge, Bell); South Carolina seceded December 1860; six more states followed before Lincoln’s inauguration.

Civil War and Reconstruction (1861–1877)

Civil War

• Confederate States of America — Jefferson Davis, president; Montgomery then Richmond as capital; eleven states in total.
• Fort Sumter (April 1861) — Confederate attack on the federal garrison; Lincoln called for troops; four more states seceded.
• First Bull Run (July 1861) — Confederate victory; dispelled illusions of a short war.
• Antietam (September 1862) — bloodiest single day of the war (~23,000 casualties); Union tactical victory; provided Lincoln political cover to issue the Emancipation Proclamation.
• Emancipation Proclamation (January 1, 1863) — executive order freeing enslaved people in Confederate states in rebellion; transformed the war into a moral crusade against slavery; freed no one in border states or occupied Confederate territory.
• Gettysburg (July 1–3, 1863) — turning-point Union victory; Confederate General Lee’s invasion of the North repulsed; ~50,000 total casualties.
• Vicksburg (July 4, 1863) — Grant’s siege gave the Union control of the Mississippi River, splitting the Confederacy.

• Sand Creek Massacre (November 29, 1864) — Colorado militia under Colonel John Chivington attacked a peaceful Cheyenne and Arapaho encampment at Sand Creek; killed approximately 150–200 people, mostly women, children, and elderly; Congress condemned it as a massacre; emblematic of the federal policy of violence against Native peoples during westward expansion.
• Appomattox Court House (April 9, 1865) — Lee surrendered to Grant; end of the Civil War. Lincoln assassinated April 14, 1865, by John Wilkes Booth at Ford’s Theatre.

Reconstruction

• 13th Amendment (1865) — abolished slavery throughout the United States.
• Black Codes (1865–1866) — laws passed by former Confederate states restricting the freedom of formerly enslaved Black people; limited mobility, required labor contracts, criminalized unemployment; functionally attempted to re-impose conditions of servitude; Congress’s outrage helped drive Radical Reconstruction.
• Freedmen’s Bureau (1865) — federal agency assisting formerly enslaved people with education, labor contracts, legal disputes, and resettlement; headed by General O. O. Howard; widely undermined by Southern resistance and presidential vetoes; disbanded 1872.
• Radical Reconstruction (1867–1877) — Congress took control from President Andrew Johnson via Reconstruction Acts (1867); divided the South into five military districts; required states to ratify the 14th and 15th Amendments and draft new constitutions granting Black male suffrage.
• 14th Amendment (1868) — citizenship to all persons born or naturalized in the U.S.; equal protection and due process clauses; overturned Dred Scott; later applied to corporations; basis for much 20th-century civil rights law.
• 15th Amendment (1870) — voting rights could not be denied on account of race, color, or previous servitude; women’s suffrage advocates such as Elizabeth Cady Stanton and Susan B. Anthony opposed it because it excluded women.
• Andrew Johnson impeachment (1868) — first presidential impeachment; acquitted by one vote in the Senate; conflict over Tenure of Office Act (which prohibited the president from removing Senate-confirmed officials without Senate approval); Johnson violated it by firing Secretary of War Stanton.
• Ku Klux Klan (founded 1865) — white supremacist organization founded in Pulaski, Tennessee; used terrorism, murder, and intimidation to suppress Black political participation during Reconstruction; Force Acts (1870–1871) temporarily broke the first Klan; it was revived in the 1910s–1920s as a mass nativist organization.
• Compromise of 1877 — disputed Hayes-Tilden election of 1876; Electoral Commission awarded Hayes the presidency; federal troops withdrew from the South; ended Reconstruction; ushered in the “Redeemer” governments and Jim Crow era.

Gilded Age and Progressive Era (1877–1917)

• Transcontinental Railroad completed (1869) — Central Pacific (building east from Sacramento, using Chinese labor) and Union Pacific (building west, using Irish and Civil War veteran labor) met at Promontory Summit, Utah; linked the coasts.
• Black Friday (September 24, 1869) — speculators Jay Gould and James Fisk attempted to corner the U.S. gold market; when the Grant administration released Treasury gold to break the corner, the gold price collapsed, wiping out many investors; tarnished the Grant administration with scandal.
• Credit Mobilier scandal (1872–1873) — construction company insiders (linked to Union Pacific Railroad) distributed stock to congressmen to avoid investigation of fraudulent billing; implicated Vice President Schuyler Colfax and other prominent politicians; exposed during the Grant era.
• Boss Tweed and Tammany Hall — William M. “Boss” Tweed led the Democratic political machine in New York City from the late 1860s until his arrest (1871); Tammany Hall controlled city patronage and contracts through bribery and electoral fraud; Thomas Nast’s cartoons in Harper’s Weekly fueled his downfall; emblematic of Gilded Age urban machine politics.
• Robber barons — powerful industrialists who accumulated enormous wealth: John D. Rockefeller (Standard Oil, used horizontal integration and rebates to monopolize refining), Andrew Carnegie (steel, later “Gospel of Wealth” philanthropy), J.P. Morgan (finance, bailed out the U.S. Treasury twice), Cornelius Vanderbilt (railroads), Jay Gould (railroads and financial manipulation).
• Dawes Act (1887) — General Allotment Act; divided tribal lands into individual 160-acre parcels for Native American heads of household; “surplus” land opened to white settlement; intended to assimilate Native peoples by making them individual landowners; resulted in the loss of approximately 90 million acres of tribal land over the following decades; repealed by the Indian Reorganization Act (1934).

• Haymarket riot (May 4, 1886) — labor rally in Chicago’s Haymarket Square turned violent when a bomb was thrown at police; eight anarchists convicted, four hanged; set back the eight-hour-workday movement and linked labor organizing to radicalism in public opinion.
• American Federation of Labor (AFL) — founded by Samuel Gompers in 1886; organized skilled craft workers rather than unskilled laborers; pursued “bread and butter” unionism (higher wages, shorter hours, better conditions) over political radicalism; dominant labor federation through much of the 20th century.
• Industrial Workers of the World (IWW / “Wobblies,” founded 1905) — radical industrial union that sought to organize all workers regardless of skill, race, or gender under the motto “One Big Union”; opposed the AFL’s exclusionary craft unionism; founders included Eugene V. Debs, “Big Bill” Haywood, and Mother Jones; led major strikes including the Lawrence “Bread and Roses” strike (1912); explicitly anti-capitalist, advocating worker control of industry; suppressed heavily under the Espionage Act (1917) and subsequent raids; Haywood fled to the Soviet Union; the IWW survived but remained small; its decentralized, industrial-union model influenced later labor organizing.
• Homestead Strike (1892) — Carnegie Steel workers at Homestead, Pennsylvania struck against wage cuts; Carnegie and manager Henry Clay Frick brought in Pinkerton agents, leading to a gun battle; state militia crushed the strike; major setback for the Amalgamated Association of Iron and Steel Workers.
• Pullman Strike (1894) — workers at George Pullman’s model company town near Chicago struck against wage cuts without corresponding rent reductions; Eugene V. Debs’s American Railway Union boycotted Pullman cars nationwide, paralyzing rail traffic; President Cleveland obtained an injunction and sent federal troops over Illinois Governor Altgeld’s objection; Debs imprisoned; established the power of federal injunctions in labor disputes.
• Coxey’s Army (1894) — unemployed workers led by Jacob Coxey marched on Washington to demand a federal public works program during the depression of the 1890s; Coxey was arrested for trespassing on the Capitol lawn; early example of a protest march on Washington.

• Populist Party / People’s Party (1890s) — agrarian movement rooted in the Farmers’ Alliances; Omaha Platform (1892) demanded free silver coinage at 16:1 ratio, graduated income tax, government ownership of railroads, direct election of senators, and the secret ballot; nominated James B. Weaver for president in 1892; William Jennings Bryan’s “Cross of Gold” speech at the 1896 Democratic convention fused Democrats and Populists; Bryan lost to McKinley; party declined afterward.
• Cross of Gold speech (1896) — William Jennings Bryan’s electrifying address at the Democratic National Convention attacking the gold standard: “You shall not press down upon the brow of labor this crown of thorns; you shall not crucify mankind upon a cross of gold”; won him the Democratic presidential nomination at age 36; he lost to William McKinley.
• Spanish-American War (1898) — “Splendid little war”; U.S. defeated Spain; gained Guam, Puerto Rico, the Philippines; Cuba nominally independent. “Remember the Maine” (the battleship USS Maine exploded in Havana harbor in February 1898, killing 266 Americans).

• Tuskegee Airmen — the 332nd Fighter Group and 477th Bombardment Group of the U.S. Army Air Forces; the first Black military aviators in the United States Armed Forces; trained at Tuskegee Army Air Field, Alabama; flew over 15,000 missions in WWII (1941–1946); their success refuted claims of Black inferiority and directly contributed to President Truman’s desegregation of the armed forces by Executive Order 9981 (1948).
• U.S. recognition of the Soviet Union (1933) — FDR normalized diplomatic relations with the USSR in November 1933, sixteen years after the Bolshevik Revolution; driven by trade interests during the Depression and strategic concerns; a significant Cold War-era predecessor issue in discussions of containment and engagement.
• Whaling industry — the American whaling industry, centered in New England ports such as New Bedford and Nantucket, peaked in the mid-19th century; at its height the U.S. whale fleet numbered over 700 ships; whale oil illuminated homes and lubricated machinery; Herman Melville’s Moby-Dick (1851) drew on his own whaling experience; the industry declined sharply after petroleum (kerosene) replaced whale oil in the 1860s.
• WikiLeaks (founded 2006) — international non-profit organization founded by Julian Assange; published classified and sensitive government and corporate documents; major releases include the Collateral Murder video (2010, U.S. airstrike in Baghdad), the Afghan War Diary and Iraq War Logs (2010), and State Department cables (2010); Assange sought asylum in the Ecuadorian embassy in London (2012–2019) before arrest; U.S. government pursued his extradition on espionage charges.
• Victoria Woodhull (1838–1927) — first woman to run for U.S. president, nominated by the Equal Rights Party in 1872 (with Frederick Douglass as her running mate, without his consent); stockbroker, newspaper editor, and suffragist; her candidacy predated women’s suffrage by nearly 50 years.
• Woodstock (August 15–18, 1969) — music festival on a farm in Bethel, New York; attracted approximately 400,000 people; featured Jimi Hendrix, Janis Joplin, The Who, Jefferson Airplane, and others; became the defining cultural event of the counterculture era; Hendrix’s rendition of “The Star-Spangled Banner” on the final morning became iconic.
• Yippies / Youth International Party (founded 1967) — countercultural and anti-war political group co-founded by Abbie Hoffman and Jerry Rubin; used street theater and provocative tactics; their disruption of the 1968 Democratic National Convention in Chicago (and the subsequent Chicago Seven trial) became major cultural flashpoints of the 1960s.
• Zoot Suit Riots (June 1943) — a series of attacks in Los Angeles in which U.S. servicemen (primarily white sailors and soldiers) attacked Mexican American, Black, and Filipino youths wearing the distinctive “zoot suit” (wide-lapel jacket, high-waist pleated trousers); the LAPD arrested many of the victims rather than the attackers; widely seen as racially motivated; Eleanor Roosevelt called them “race riots,” which Hearst newspapers denied.
