The History of the United States

The First Peoples

Before European settlers arrived in the Americas, diverse Indigenous tribes and nations thrived for thousands of years. These First Nations had complex cultures, religions, and social structures. The archaeological site at Clovis, New Mexico, offers evidence of human presence in America from around 13,500 years ago.

European Exploration

Europeans began exploring the Americas in the late 15th century, with Christopher Columbus’ 1492 voyage. Sponsored by Spain, Columbus stumbled upon the Caribbean while seeking a western route to Asia. These explorations soon led to a “Columbian Exchange” — a massive transfer of plants, animals, disease, and culture between the Old and New Worlds.

Spanish Colonization

Spain established the first permanent European settlements in the Americas, including St. Augustine in Florida (1565), the oldest continuously inhabited European-founded city in the U.S. Spanish explorers sought riches, conversions to Christianity, and territorial claims. In the Southwest, Spanish missions, like those in modern-day California, New Mexico, and Texas, sought to convert Indigenous peoples.

English Settlements

In 1585, Sir Walter Raleigh tried establishing the first English colony on Roanoke Island (present-day North Carolina), but it failed mysteriously, becoming known as the “Lost Colony.”

The English had more success in 1607 with Jamestown in Virginia. Initially, the settlers faced starvation and conflicts with Indigenous tribes, but the colony survived, especially after the introduction of tobacco cultivation by John Rolfe.

In 1620, the Mayflower delivered the Pilgrims, a group of religious separatists, to Plymouth in modern-day Massachusetts. The Plymouth colony, while small, was significant for its Mayflower Compact, a pioneering effort in self-governance.

Dutch and French Exploration

The Dutch established New Netherland, encompassing parts of modern-day New York, New Jersey, Delaware, and Connecticut. The city of New Amsterdam on Manhattan Island later became New York City.

The French explored the Mississippi River basin, laying the groundwork for the fur trade in the Great Lakes and Midwest regions. They founded Quebec in Canada and established a vast territory known as New France, which included parts of modern-day Louisiana.

The Emergence of Slavery

The English colonies began practicing African chattel slavery in the early 17th century. In 1619, the first African slaves were brought to Jamestown. Over the next two centuries, the transatlantic slave trade grew, and African slavery became institutionalized in the colonies, especially in the Southern plantations where labor-intensive crops like tobacco, indigo, and rice were grown.

Religious Diversity and Tensions

The mid-17th century saw the formation of Maryland as a haven for Catholics. Meanwhile, the Puritans established the Massachusetts Bay Colony in 1630, practicing a strict form of Protestantism. Religious tension was prevalent. The persecution of dissenters in Massachusetts led to the founding of other New England colonies, including Rhode Island by Roger Williams and Connecticut by Thomas Hooker.

Colonial Expansion and Conflicts

As European colonies expanded, they displaced Indigenous peoples and often came into conflict. Wars such as the Pequot War (1636–1638) and King Philip’s War (1675–1678) were brutal and had devastating impacts on Indigenous tribes.

Simultaneously, tensions among European powers led to numerous colonial wars, setting the stage for global conflict in the 18th century.

The Late 17th Century: Tensions and Changes

The late 1600s saw the English taking over New Netherland from the Dutch, renaming it New York. The establishment of the Carolinas and Pennsylvania expanded English territorial claims.

In 1676, dissatisfaction with Virginia’s colonial government led to Bacon’s Rebellion, a precursor to future colonial revolts against perceived injustices.

By the end of the 17th century, the thirteen English colonies, each with its unique characteristics and governance, were taking shape along the Atlantic seaboard. Their population, a mix of English settlers, Indigenous peoples, enslaved Africans, and other Europeans, set the stage for a dynamic and often turbulent 18th century.

Colonial Growth and Diversification

By the 18th century, the American colonies were growing rapidly. Trade, agriculture, and a high birth rate led to a population boom. Major cities like Boston, Philadelphia, New York, and Charleston became hubs of commerce and culture. The colonies also became more diverse, with increased immigration from Europe, including Germans, Scots-Irish, and other groups, further enriching the cultural fabric.

The Enlightenment and Great Awakening

The Enlightenment, a European intellectual movement emphasizing reason and individual rights, began to influence colonial thought. Key figures like Benjamin Franklin epitomized the American Enlightenment with his experiments, inventions, and writings.

Simultaneously, the Great Awakening, a religious revival movement, swept the colonies from the 1730s to 1760s. Itinerant preachers like George Whitefield and Jonathan Edwards emphasized personal salvation and emotional religious experiences. This movement not only revived religious fervor but also fostered a sense of shared American identity.

Continued Native American Displacement

European expansion and settlement continued to push Native American tribes westward, leading to further tensions and conflicts. Tribes were forced to adapt, resist, or form alliances with various colonial powers.

Colonial Wars and Global Conflict

Throughout the 18th century, European powers clashed, and their colonial territories became theaters of war. Key among these was the French and Indian War (1754–1763), known globally as the Seven Years’ War. It began over territorial disputes in the Ohio River Valley between the British and French, with various Native American tribes siding with both powers. The war ended with the Treaty of Paris in 1763, which saw the British emerge as the dominant colonial power, taking control of Canada from France and Florida from Spain.

British Policies and Colonial Discontent

To pay off war debts and finance the administration of its vast empire, Britain sought to extract more revenue from the colonies. The Sugar Act (1764), Stamp Act (1765), and Townshend Acts (1767) imposed new taxes and duties on the colonies. These measures were met with widespread resistance, as colonists believed they violated their rights as Englishmen to “no taxation without representation.”

Protests erupted, with notable events like the Stamp Act Congress and the formation of groups like the Sons of Liberty. By 1770, tensions peaked with the Boston Massacre, where British troops killed five colonists during a confrontation.

Emergence of Revolutionary Ideals

Colonial leaders began to articulate grievances against British policies. Publications like Thomas Paine’s “Common Sense” (1776) and the Virginia Resolves challenged British authority and advocated for colonial rights.

Furthermore, committees of correspondence, formed throughout the colonies, facilitated inter-colonial communication and united opposition against British measures.

The Boston Tea Party and the Intolerable Acts

In 1773, to protest the British monopoly on tea, the Sons of Liberty, dressed as Mohawk Indians, dumped an entire shipment of tea into Boston Harbor, an event now known as the Boston Tea Party.

In response, the British enacted the Coercive Acts (known in the colonies as the Intolerable Acts) in 1774. These acts closed Boston Harbor, altered the Massachusetts charter, and allowed British officials to be tried in Britain or Canada for crimes committed in the colonies. Another act allowed for the quartering of British troops in colonial homes.

These actions further alienated the colonists and pushed them toward open revolt.

Boston Tea Party

The First Continental Congress

In September 1774, representatives from 12 of the 13 colonies met in Philadelphia for the First Continental Congress. They debated their relationship with Britain and agreed to boycott British goods until the Intolerable Acts were repealed. They also began preparing for possible military conflict.

As 1775 dawned, the stage was set for the beginning of the American Revolution, a conflict that would determine the fate of the colonies and lead to the birth of a new nation.

The Outbreak of War

The simmering tensions between the British and the colonists erupted into open conflict in April 1775. British troops, aiming to seize colonial weapons in Concord, Massachusetts, clashed with local militias at Lexington and Concord. The “shot heard round the world” marked the beginning of the Revolutionary War.

The Second Continental Congress and the Declaration of Independence

Meeting in May 1775, the Second Continental Congress acted as a de facto government for the colonies. They appointed George Washington as the commander of the Continental Army and began to manage the war effort.

By 1776, it was clear that reconciliation with Britain was unlikely. On July 4th, the Congress adopted the Declaration of Independence, penned mainly by Thomas Jefferson. This document proclaimed the colonies’ right to be free and independent states.

Major Battles and Turning Points

The war saw several pivotal moments:

• The Siege of Boston (1775–1776): Washington’s first significant military engagement, resulting in a British withdrawal.
• Battle of Saratoga (1777): A significant American victory that convinced France to enter the war on the American side.
• Winter at Valley Forge (1777–1778): A period of immense hardship for the Continental Army, but one that also saw its transformation into a more effective fighting force under the training of Baron von Steuben.
• Battle of Yorktown (1781): With the aid of the French, Washington’s troops cornered British General Cornwallis, leading to his surrender and effectively ending the war.

Foreign Assistance

The American Revolution was not just a colonial rebellion. It became a global conflict with France, Spain, and the Netherlands entering the war against Britain. The French, especially, played a vital role, providing troops, supplies, and naval support.

The American Revolution

Life on the Home Front

The war impacted every aspect of colonial life. While many supported the Revolution, loyalists (colonists loyal to the King) faced persecution and often fled to Canada or Britain. Women took on new roles, running farms and businesses in the absence of men and even serving as spies or camp followers.

The Treaty of Paris (1783)

After years of fighting, both sides were ready for peace. The Treaty of Paris formally ended the war and recognized the independence of the United States. The new nation’s borders extended from the Atlantic Ocean to the Mississippi River and from Canada to Florida.

The Articles of Confederation

The newly independent states first governed themselves under the Articles of Confederation, adopted in 1781. This document established a weak central government with limited powers. Over time, its inadequacies became apparent, with economic turmoil and the inability to address interstate disputes or maintain a standing army.

Shays’ Rebellion (1786–1787)

Economic hardships, particularly among farmers, led to this uprising in Massachusetts. While quickly put down, it highlighted the weaknesses of the Articles of Confederation and the need for a stronger central government.

The Constitutional Convention (1787)

In response to the issues arising from the Articles, delegates from the states gathered in Philadelphia. Initially meant to amend the Articles, the Convention ended up drafting a new document, the United States Constitution. This new framework of government created a federal system with a balance of powers between three branches: executive, legislative, and judicial.

After a spirited debate between Federalists (supporters of the Constitution) and Anti-Federalists (opponents who feared a strong central government), the Constitution was ratified in 1788.

The New Republic

In 1789, George Washington was inaugurated as the first President of the United States, symbolizing the birth of a new republic. The following years would test the resilience of the young nation’s institutions and its commitment to its founding ideals.

George Washington’s presidency set numerous precedents. Among his significant achievements were:

• Establishment of the Federal Judiciary: The Judiciary Act of 1789 laid the groundwork for the federal court system.
• Whiskey Rebellion (1794): When a federal tax on whiskey led to rebellion in Pennsylvania, Washington personally led troops to quell it, asserting federal authority.
• Farewell Address: As he declined a third term, Washington warned against permanent foreign alliances and political factions.

George Washington

Advent of Political Parties

Despite Washington’s warnings, political factions emerged. The Federalists, led by John Adams and Alexander Hamilton, advocated for a strong central government and close ties with Britain. The Democratic-Republicans, led by Thomas Jefferson and James Madison, championed states’ rights and favored France in foreign policy.

The Adams Presidency (1797–1801), John Adams faced various challenges:

• XYZ Affair: A diplomatic incident with France almost led to war, but Adams chose peace, a decision that hurt his political standing but likely benefited the young nation.
• Alien and Sedition Acts (1798): These controversial laws targeted foreigners and critics of the government, leading to claims of overreach and tyranny.

The Revolution of 1800

The election of 1800 was a pivotal moment. Thomas Jefferson defeated John Adams, marking the first peaceful transfer of power between political rivals in U.S. history.

The Jefferson Presidency (1801–1809), Jefferson’s tenure was marked by significant events:

• Louisiana Purchase (1803): The U.S. bought a vast territory from France, doubling its size. This acquisition sparked debates over its constitutionality and the expansion of slavery.
• Lewis and Clark Expedition (1804–1806): Commissioned by Jefferson, this exploration of the West gathered scientific data and made contact with numerous Indigenous tribes.
• Embargo Act (1807): Aiming to pressure Britain and France during the Napoleonic Wars, this act halted American exports, but it severely hurt the U.S. economy.

The Madison Presidency (1809–1817), James Madison, the “Father of the Constitution,” faced significant foreign policy challenges:

• War of 1812: Persistent British provocations, like the impressment of American sailors and interference with American trade, led the U.S. to declare war on Britain. The war saw the burning of Washington, D.C., but also American victories like the Battle of New Orleans. It concluded with the Treaty of Ghent in 1814, restoring the status quo.
• Hartford Convention (1814–1815): New England Federalists, opposing the war, met to discuss their grievances. While they didn’t call for secession, the convention further weakened the already declining Federalist Party.

The Era of Good Feelings

Post-war, a sense of national purpose and a desire for unity characterized American politics, leading to what’s often termed the “Era of Good Feelings.” However, underlying tensions, especially concerning slavery and economic interests, hinted at future conflicts.

Post-War Nationalism

After the War of 1812, a surge of nationalism swept the U.S. This was evident in various facets:

• American System: Proposed by Speaker of the House Henry Clay, this plan aimed to unify the nation’s economy. It advocated for a strong national bank, protective tariffs, and federally funded internal improvements.
• Monroe Doctrine (1823): Under President James Monroe, this policy warned European powers against further colonization or intervention in the Americas. It became a cornerstone of U.S. foreign policy.

Economic and Technological Changes

The early 19th century saw rapid economic and technological growth:

• Industrialization: The Northeast became a hub for manufacturing, with innovations like the cotton gin and textile mills transforming the economy.
• Transportation Revolution: Canals like the Erie Canal, steamboats, and later, railroads, improved connectivity, fueling economic growth.
• The Market Revolution: Improved transportation and communication allowed for a broader market-based economy, impacting labor, agriculture, and production methods.

The Missouri Compromise (1820)

As the U.S. expanded westward, the issue of slavery in new territories became contentious. The Missouri Compromise admitted Missouri as a slave state and Maine as a free state, maintaining the Senate’s balance. It also prohibited slavery above the 36°30' parallel in the Louisiana Purchase territory.

Era of the Common Man: The 1820s and 1830s witnessed greater political democratization:

• Election of Andrew Jackson (1828): A war hero and the people’s champion, Jackson’s presidency marked a shift towards populism.
• Indian Removal Act (1830): Despite its populist veneer, Jackson’s era had dark aspects. This act led to the forced removal of Native American tribes from their ancestral lands, culminating in the tragic “Trail of Tears.”
• Nullification Crisis (1832–1833): South Carolina, opposing high federal tariffs, declared them null and void. The crisis, which threatened secession, was resolved when Jackson took a firm stand, and a compromise tariff was introduced.

Reform Movements: Several movements aimed to improve society:

• Religious Revival: The Second Great Awakening spurred religious fervor, emphasizing individual salvation and morality.
• Abolition: Calls to end slavery grew louder, with figures like Frederick Douglass, William Lloyd Garrison, and Harriet Tubman playing pivotal roles.
• Women’s Rights: The Seneca Falls Convention (1848) marked the beginning of the organized women’s rights movement. Leaders like Elizabeth Cady Stanton and Lucretia Mott advocated for women’s suffrage and equality.
• Temperance and Education: Movements aimed to curb alcohol consumption and promote public education, seeing both as means to improve society.

Art and Literature

This period also witnessed a cultural renaissance. The Hudson River School painters celebrated American landscapes, while writers like Washington Irving, James Fenimore Cooper, and Edgar Allan Poe shaped American literature.

Manifest Destiny

The belief that the U.S. was destined to stretch from the Atlantic to the Pacific was termed “Manifest Destiny.” This idea, rooted in economic, racial, and religious sentiments, drove westward expansion.

Texas and the Mexican-American War

• Annexation of Texas (1845): Initially an independent republic after breaking away from Mexico in 1836, Texas was annexed to the U.S., which angered Mexico and added another slave state.
• Mexican-American War (1846–1848): A conflict over Texas’s southern border and broader U.S. ambitions in the Southwest. The U.S. emerged victorious.
• Treaty of Guadalupe Hidalgo (1848): This treaty ended the war, with Mexico ceding a vast territory (including present-day California, Arizona, and New Mexico) to the U.S. in exchange for $15 million.

California Gold Rush (1849)

The discovery of gold in California led to a massive migration. “Forty-niners” from across the world flocked to the state, transforming its economy and demographics.

California Gold Rush

Compromise of 1850

With new territories acquired, the slavery question resurfaced. Senator Henry Clay proposed a series of measures:

• California was admitted as a free state.
• The territories of Utah and New Mexico could decide on slavery via popular sovereignty.
• The slave trade (but not slavery) was abolished in Washington, D.C.
• A stringent Fugitive Slave Act was introduced, requiring citizens to assist in capturing runaway slaves.

Kansas-Nebraska Act (1854)

Proposed by Senator Stephen Douglas, this act allowed the territories of Kansas and Nebraska to decide on slavery via popular sovereignty. It nullified the Missouri Compromise’s restriction on slavery expansion, leading to violent conflicts in Kansas, known as “Bleeding Kansas.”

Rise of the Republican Party

In response to the perceived pro-slavery tilt of national politics, the Republican Party emerged in the mid-1850s. Comprising former Whigs, Free-Soilers, and anti-slavery Democrats, it aimed to halt slavery’s expansion.

Dred Scott v. Sandford (1857)

In this controversial Supreme Court decision, Chief Justice Roger B. Taney declared that African Americans couldn’t be citizens and that Congress had no authority to ban slavery in the territories. The ruling further inflamed sectional tensions.

John Brown’s Raid (1859)

Abolitionist John Brown’s attempt to incite a slave rebellion by capturing the federal arsenal at Harpers Ferry ended in his capture and execution. While many condemned his tactics, his commitment deepened the North’s resolve against slavery.

Election of 1860

The election saw four main candidates, with Abraham Lincoln representing the Republicans. Lincoln’s victory, without carrying a single southern state, convinced many southerners of their diminished voice in national affairs. His election set the stage for the most significant crisis in American history.

The Civil War (1861–1865)

The conflict between the North and South, rooted in economic, cultural, and political differences — most significantly over slavery — escalated into a full-blown war.

• Secession: Following Lincoln’s election, South Carolina seceded in December 1860. By February 1861, seven states had left the Union, forming the Confederate States of America under President Jefferson Davis.
• Fort Sumter (April 1861): The first shots of the Civil War were fired in South Carolina, pushing more states to secede and rallying the North.
• Major Battles: Among the numerous significant battles were Bull Run, Antietam (the bloodiest single day), Gettysburg (a turning point), and Sherman’s March to the Sea.
• Emancipation Proclamation (1863): Lincoln declared all slaves in Confederate-held territory free, giving the war a moral purpose beyond preservation of the Union.
• End of the War: On April 9, 1865, Confederate General Robert E. Lee surrendered to Union General Ulysses S. Grant at Appomattox Courthouse in Virginia. Lincoln’s assassination shortly after, on April 15, further shook the nation.

American Civil War

Reconstruction (1865–1877)

This period aimed to reintegrate the South into the Union and redefine African Americans’ status.

Presidential Reconstruction: Lincoln’s plan aimed for leniency, requiring only 10% of voters in a southern state to pledge loyalty to the Union for readmission. His successor, Andrew Johnson, tried to continue this approach but faced criticism for being too lenient on the South.

Radical Reconstruction: The Radical Republicans in Congress sought to ensure African Americans’ rights. They passed the Civil Rights Act of 1866 and the Reconstruction Acts, placing the South under military occupation.

Constitutional Amendments:

• 13th (1865): Abolished slavery.
• 14th (1868): Granted citizenship to all born or naturalized in the U.S. and ensured equal protection under the law.
• 15th (1870): Prohibited voting discrimination based on race or previous servitude.

Rise of the Ku Klux Klan: This white supremacist group formed to intimidate Black voters and white Republicans, using violence to restore white Democratic power in the South.

End of Reconstruction: The contested election of 1876 resulted in a compromise. Republican Rutherford B. Hayes became president in exchange for the withdrawal of federal troops from the South, effectively ending Reconstruction.

Legacy of Reconstruction

While Reconstruction saw landmark achievements in African Americans’ rights, its collapse enabled the rise of Jim Crow laws, disenfranchising Black citizens and enforcing racial segregation. The struggle for civil rights would continue for nearly another century.

The Gilded Age

Named after Mark Twain’s novel, this era was marked by significant economic growth but also stark income inequality, political corruption, and corporate excess.

• Industrialization: Innovators like Thomas Edison and Andrew Carnegie transformed industries. Railroads expanded, factories proliferated, and the U.S. became a leading industrial power.
• Robber Barons and Philanthropists: Figures like John D. Rockefeller, Carnegie, and J.P. Morgan amassed huge wealth. They were criticized for their business practices but also established enduring philanthropic legacies.
• Labor Movement: Poor working conditions and low wages led to the rise of labor unions and strikes, like the Haymarket Riot (1886) and the Pullman Strike (1894).
• Urbanization: Cities grew rapidly, leading to both architectural marvels and overcrowded tenements. Newcomers, including immigrants and rural migrants, flocked to urban centers.

Populist Movement

Facing economic challenges, farmers joined forces with labor activists to challenge big business’s power. The Populist Party’s 1892 platform called for the direct election of senators, a graduated income tax, and the coinage of silver to combat deflation.

Westward Expansion

• Indian Wars: As settlers pushed west, Native American resistance was met with military force. Battles like Little Bighorn (1876) were followed by tragedies like the Wounded Knee Massacre (1890).
• Homestead Act (1862): This act granted land to settlers willing to develop it, promoting westward movement.
• Closing the Frontier: In 1890, the U.S. Census declared the frontier closed, signifying the end of westward expansion.

American Homesteaders

American Imperialism

Fueled by economic, strategic, and ideological motivations, the U.S. began to seek territories beyond its borders:

• Purchase of Alaska (1867): Secretary of State William Seward purchased Alaska from Russia, a move initially mocked as “Seward’s Folly” but later recognized as a strategic acquisition.
• Annexation of Hawaii (1898): American businessmen and settlers, having overthrown Queen Liliuokalani, pushed for Hawaii’s annexation.
• Spanish-American War (1898): Sympathy for Cuban rebels, economic interests, and the mysterious sinking of the USS Maine propelled the U.S. into war with Spain. The U.S. emerged victorious, acquiring the Philippines, Guam, and Puerto Rico.
• Open Door Policy (1899): Seeking to protect its interests in China, the U.S. proposed this policy, ensuring all nations could trade with China on equal terms.

Cultural and Social Changes

• Progressive Ideas: Even as the Gilded Age glittered, the seeds of the Progressive Era were sown. Muckraking journalists began exposing societal and governmental issues.
• Jim Crow South: Post-Reconstruction South saw the rigid imposition of segregationist laws and practices, disenfranchising Black Americans.

The Progressive Era (1900–1920): This era saw reforms addressing the problems of the Gilded Age:

• Muckrakers: Journalists like Upton Sinclair and Ida Tarbell exposed societal and corporate ills, influencing public opinion and policy changes.
• Reforms: Initiatives included antitrust laws, consumer protection (Pure Food and Drug Act), and conservation of natural resources by figures like President Teddy Roosevelt.
• Women’s Suffrage: After decades of activism, the 19th Amendment (1920) granted women the right to vote.
• Temperance and Prohibition: Advocacy from groups like the Women’s Christian Temperance Union culminated in the 18th Amendment (1919), prohibiting alcohol. It was later repealed by the 21st Amendment (1933).

Susan B. Anthony

World War I (1914–1918): Although the war began in Europe in 1914, the U.S., under President Woodrow Wilson, remained neutral until 1917.

• U.S. Involvement: The sinking of the Lusitania, the Zimmerman Telegram, and unrestricted submarine warfare by Germany influenced the U.S. to join the Allies.
• Home Front: The war accelerated American industry. Propaganda campaigns bolstered support, while acts like the Espionage Act (1917) suppressed dissent.
• End of War and Treaty of Versailles: The war concluded in 1918, and the subsequent treaty imposed heavy reparations on Germany. The U.S., however, never ratified the treaty or joined the League of Nations, signaling a return to isolationism.

The Roaring Twenties: This decade was marked by economic prosperity, cultural dynamism, and social change:

• Economic Boom: Innovations, mass production (especially in the auto industry), and consumerism drove prosperity.
• Cultural Movements: The Harlem Renaissance celebrated African American culture. The Lost Generation, including writers like F. Scott Fitzgerald and Ernest Hemingway, critiqued society.
• Social Changes: The flapper symbolized new freedoms and roles for women. Meanwhile, the Scopes Trial (1925) showcased the clash between modernity and traditional values.

The Great Depression (1929–1939): The stock market crash of 1929 triggered a severe economic downturn:

• Economic Collapse: Banks failed, businesses shuttered, and unemployment soared.
• Dust Bowl: Mismanaged farming and drought led to massive dust storms in the Midwest, displacing many families.
• New Deal: President Franklin D. Roosevelt introduced a series of programs and reforms to alleviate the Depression’s effects, strengthen the banking system, provide jobs, and stimulate recovery.
• Cultural Impact: The Depression influenced literature, music, and art. The plight of ordinary Americans was captured by figures like John Steinbeck in “The Grapes of Wrath.”

The Great Depression

World War II (1939–1945)

• Path to War: While the war began in 1939 with Germany’s invasion of Poland, the U.S. remained neutral until the Japanese attack on Pearl Harbor on December 7, 1941.
• Allied Powers: The U.S. joined the UK, USSR, and other nations against the Axis Powers — Germany, Italy, and Japan.
• European Front: D-Day (June 6, 1944) marked a significant turning point, as Allied forces stormed the beaches of Normandy. The war in Europe culminated with Germany’s surrender on May 7, 1945.
• Pacific Front: Key battles included Midway and Iwo Jima. The U.S. dropped atomic bombs on Hiroshima and Nagasaki in August 1945, leading to Japan’s surrender on September 2.
• Home Front: Wartime production ended the Great Depression. Women took on roles in factories (symbolized by “Rosie the Riveter”), and propaganda campaigns galvanized support. However, racial tensions persisted, evidenced by the Zoot Suit Riots and the internment of Japanese Americans.

World War II

Post-War World and the United Nations

• In the war’s aftermath, the United Nations was established in 1945, aiming to foster international cooperation and prevent future conflicts.

The Cold War Begins

The post-war era saw the U.S. and the USSR, former allies, become adversaries due to ideological differences — capitalism vs. communism.

• Iron Curtain and Containment: Winston Churchill’s term described the division of Europe. The U.S. adopted a policy of containment, seeking to prevent communism’s spread.
• Truman Doctrine and Marshall Plan: These initiatives aimed to support nations resisting communism and help war-torn European countries rebuild, respectively.
• Berlin Airlift (1948–1949): When the USSR blockaded West Berlin, the U.S. and its allies supplied the city via air, highlighting Cold War tensions.

Korean War (1950–1953)

A proxy war in the broader U.S.-Soviet rivalry, this conflict saw North Korean communist forces, backed by China and the USSR, face off against South Korean and U.S.-led United Nations forces. The war ended in an armistice, with Korea remaining divided at the 38th parallel.

Domestic Impacts of the Cold War

• Red Scare and McCarthyism: Fears of communist infiltration led to a nationwide witch hunt, notably by Senator Joseph McCarthy, targeting alleged communist sympathizers.
• Space Race: After the USSR launched Sputnik in 1957, the U.S. intensified its space exploration efforts, marking another competitive front in the Cold War.
• Civil Rights Movement: Post-war America saw growing calls for civil rights, particularly from African Americans. Landmark moments included the Brown v. Board of Education decision (1954) and Rosa Parks’ Montgomery Bus Boycott (1955–1956).

Civil Rights Movement

• Sit-Ins and Freedom Rides (1960–1961): Nonviolent protests such as sit-ins at segregated lunch counters and Freedom Rides challenging segregation in interstate buses took center stage.
• March on Washington (1963): Over 200,000 demonstrators gathered in a unified call for justice and equality. Martin Luther King Jr.’s “I Have a Dream” speech became an emblematic moment.
• Civil Rights Act of 1964: Signed by President Lyndon B. Johnson, this legislation aimed to end segregation in public places and banned employment discrimination on the basis of race, color, religion, sex, or national origin.
• Voting Rights Act of 1965: This act prohibited racial discrimination in voting, ensuring federal oversight in areas with historic discrimination.

Martin Luther King

Vietnam War (1965–1973): Although U.S. involvement began earlier, large-scale troop deployment started in 1965.

• Reasons for U.S. Involvement: To prevent a communist takeover of South Vietnam and to contain the spread of communism.
• Tet Offensive (1968): A massive, coordinated communist assault on numerous South Vietnamese cities, this event, although militarily repelled, marked a turning point by eroding U.S. public support for the war.
• Anti-War Protests: As the war dragged on, protests escalated, especially on college campuses. The 1968 Democratic National Convention in Chicago saw significant clashes between protesters and police.

Cultural and Social Upheavals

• Counterculture: Embodying anti-establishment sentiments and a desire for change, this movement was embodied by the hippies, with its epicenter in San Francisco’s Haight-Ashbury district. The 1969 Woodstock festival became a symbol of this era.
• Women’s Liberation Movement: Building on earlier feminist movements, the 1960s saw renewed calls for women’s rights. Betty Friedan’s “The Feminine Mystique” (1963) criticized societal expectations, and organizations like NOW (National Organization for Women) pushed for equality.
• Other Movements: The decade witnessed a surge in other movements, including environmentalism (spurred by Rachel Carson’s “Silent Spring”), the Chicano Movement advocating for Mexican American rights, and the Stonewall Riots (1969) in New York, marking the beginning of the modern LGBTQ+ rights movement.

Harvey Milk

Assassinations

The ’60s were marred by the assassinations of significant figures, leaving indelible marks on the nation’s psyche:

• John F. Kennedy (1963): The 35th president was assassinated in Dallas, Texas.
• Martin Luther King Jr. (1968): The civil rights leader was shot in Memphis, Tennessee.
• Robert F. Kennedy (1968): JFK’s brother and a presidential candidate, he was killed in Los Angeles.

Vietnam War’s Conclusion

• Paris Peace Accords (1973): These accords ended U.S. military involvement in Vietnam. However, fighting continued between North and South Vietnam until the North’s victory in 1975, leading to Vietnam’s unification under communist rule.
• War’s Aftermath: The conflict left deep scars on American society. Veterans faced challenges reintegrating, and the public grappled with the war’s moral and political implications.

Watergate Scandal

• Break-In and Cover-Up (1972): A break-in at the Democratic National Committee headquarters in the Watergate complex was traced back to members of President Nixon’s reelection campaign.
• Investigations: Reporters, notably Bob Woodward and Carl Bernstein of The Washington Post, played a pivotal role in uncovering the depth of the scandal. Televised Senate hearings revealed a web of deceit, cover-ups, and illegal activities.
• Nixon’s Resignation (1974): Facing near-certain impeachment, Richard Nixon became the first U.S. president to resign. Gerald Ford, his successor, controversially pardoned him.

Nixon Resigns
