Is this your course?

This page is for AQA A-level History, option 1K: The Making of a Superpower: USA, 1865–1975.

It begins just after the American Civil War and ends as the United States leaves Vietnam. Your course is a breadth study: you need to see how politics, the economy, society and America’s role in the world changed across 110 years.

If your course begins in 1945 and ends in 1980, you probably need AQA 2Q: The American Dream instead. If it is called Civil Rights in the USA, 1865–1992, you probably need OCR Y319.

Start here: the United States in 1865

In 1865 the United States had survived a civil war. The Union had defeated the Confederacy, and slavery had been abolished. Yet victory did not answer the hardest question: what would freedom mean in practice for four million formerly enslaved people?

The country was a federation. Power was divided between the federal government in Washington and individual state governments. The Constitution separated authority among the president, Congress and Supreme Court. That system could protect liberty, but it could also make reform slow and allow hostile states to resist federal law.

The country was also expanding westward. That expansion created farms, railways, mines and new states, while dispossessing Native peoples through warfare, broken treaties and reservation policy. In the decades ahead, enormous industrial growth would create both spectacular wealth and deep inequality.

Six words to know

• Reconstruction: the attempt after the Civil War to rebuild the South and establish freedom and citizenship for formerly enslaved people.
• Federal: belonging to the national government of the United States.
• Segregation: the enforced separation of racial groups, especially through the Jim Crow system in the South.
• Industrialisation: the growth of factory production, railways, large businesses and urban work.
• Progressivism: a broad reform movement that tried to curb corruption and some abuses of industrial society.
• Superpower: a state with exceptional economic, military and political influence across the world.

The basic story

1. Reconstruction offered a new freedom — then the nation retreated

The Thirteenth Amendment abolished slavery. The Fourteenth made citizenship and equal protection part of the Constitution. The Fifteenth sought to protect Black male voting rights. During Congressional Reconstruction, Black men voted and held office, while schools, churches and community organisations expanded.

These changes met organised white resistance. Groups including the Ku Klux Klan used terror to destroy Black political participation. Southern states later built the Jim Crow system of segregation and disfranchisement. When federal commitment weakened and troops left the South in 1877, constitutional rights remained on paper but were often denied in practice.

Quick check: Why did the end of slavery not automatically produce equal citizenship?

2. Industry made the USA richer, larger and more unequal

Railways joined a continental market. Steel, oil, finance and mass production created giant corporations and fortunes. Millions of migrants moved to American cities, while farmers and workers faced insecure prices, low wages and dangerous conditions.

Government was often close to business, and politics acquired a reputation for patronage and corruption. Workers formed unions and sometimes went on strike; employers, courts and governments frequently resisted them. Farmers and reformers built the Populist movement, arguing that concentrated wealth had captured democracy.

Westward growth also depended on the seizure of Native land. Federal policy combined military force, reservations and forced cultural assimilation. The national success story therefore carried very different meanings for railroad owners, workers, Black citizens and Native nations.

Quick check: Give one way industrial growth increased American power and one way it created conflict.

3. Reform at home accompanied expansion abroad

From the 1890s, Progressives tried to make government more effective and restrain some abuses of corporate power. Theodore Roosevelt presented the presidency as a force for national reform. Woodrow Wilson introduced further economic changes, although Progressive reform often excluded Black Americans and accepted racial hierarchy.

At the same time, the United States became more active overseas. War with Spain in 1898 brought an American empire, including control of the Philippines. The language of liberty sat uneasily beside conquest abroad and segregation at home.

America entered the First World War in 1917. Its economic and military contribution showed its growing strength, but the post-war Senate rejected membership of the League of Nations. The USA was powerful without yet accepting permanent responsibility for world order.

Quick check: What contradiction connected reform, race and overseas expansion?

4. The 1920s boom collapsed into Depression

Cars, electrical goods, advertising and consumer credit transformed life for many Americans in the 1920s. Yet prosperity was uneven. Farmers struggled, racial violence continued, immigration was restricted and fear of radicalism narrowed political debate.

The Wall Street Crash of 1929 was followed by bank failures, unemployment and a collapse in demand. President Hoover took some action but remained wary of direct federal relief. Franklin D. Roosevelt’s New Deal greatly expanded the federal government’s responsibility for economic recovery and social security.

The New Deal provided work, relief and regulation, but it did not distribute protection equally. Black workers were often disadvantaged by local administration and by exclusions designed to preserve support from white southern Democrats. The Second World War, more than the New Deal alone, finally restored full employment.

Quick check: Why was the New Deal a turning point even though it did not end every inequality?

5. Global war turned great power into superpower

The United States entered the Second World War after Japan attacked Pearl Harbor in December 1941. Wartime production expanded industry and federal power. By 1945, much of Europe and Asia had been devastated while the American economy and military had grown enormously. The United States possessed the atomic bomb and helped design the new international order.

Rivalry with the Soviet Union then shaped American policy. The Truman Doctrine, Marshall Plan, NATO and wars in Korea and Vietnam reflected a policy of containing communism. Cold War fear also affected life at home through loyalty investigations and McCarthyism.

Superpower status brought influence, but also costs and contradictions. American leaders defended freedom abroad while millions of citizens still faced segregation and discrimination at home.

6. Civil-rights activism changed the nation, but equality remained unfinished

Black Americans were never passive. Across the period they built churches, newspapers, businesses and political organisations; challenged violence and segregation; migrated in search of safety and work; and pressed the federal government to enforce citizenship.

After 1945, legal challenges and mass activism intensified. Brown v. Board of Education, the Montgomery bus boycott, student sit-ins, Freedom Rides, Birmingham and Selma exposed the violence required to maintain segregation. Martin Luther King Jr was important, but so were local organisers, women activists, students, lawyers and ordinary participants.

Federal action mattered. The Civil Rights Act of 1964 and Voting Rights Act of 1965 attacked legal segregation and disfranchisement. Yet discrimination in housing, jobs, policing and education persisted, especially outside the simple legal framework of southern Jim Crow. Urban uprisings and Black Power expressed both new confidence and frustration at the limits of reform.

Quick check: Why would it be misleading to explain civil-rights change only through presidents and famous national leaders?

7. Vietnam exposed the limits of American power

Post-war prosperity helped sustain confidence in American leadership, but it did not remove poverty or political conflict. Presidents Kennedy and Johnson expanded involvement in Vietnam. Johnson also launched the Great Society, including anti-poverty measures and major civil-rights legislation, but war consumed money and political attention.

The Tet Offensive of 1968 deepened doubt about official claims of progress. Protest, racial conflict and political violence fractured the liberal confidence of the early 1960s. Richard Nixon reduced direct American involvement while widening parts of the war; the Watergate scandal then revealed serious abuse of presidential power.

In 1975 Saigon fell to communist forces. The United States remained immensely powerful, but it had discovered that economic strength, advanced weapons and global reach could not guarantee political success.

You can stop here

If you can explain the seven stages above in your own words, you already have a useful map of the course. You do not need to memorise every president or event today.

What the AQA Component 1 exam asks you to do

This breadth study is examined in a two-hour, 30-minute paper worth 80 marks. In Section A, you answer one compulsory 30-mark question comparing and evaluating three historians’ interpretations. You must test their arguments using accurate knowledge of the period. In Section B, you answer two 25-mark essays from a choice of three.

The essays are deliberately broad: AQA says each will cover at least 20 years. That is why this page keeps asking you to connect developments and judge change over time rather than memorise isolated events.

Six anchor dates

• 1865: Civil War ends and the Thirteenth Amendment abolishes slavery.
• 1877: federal Reconstruction effectively ends in the South.
• 1898: Spanish–American War signals a more assertive overseas role.
• 1929: Wall Street Crash begins the crisis that becomes the Great Depression.
• 1945: Second World War ends with the USA established as a global superpower.
• 1975: Saigon falls, exposing the limits of American power at the course endpoint.

A first course question

Which changed the United States more between 1865 and 1975: the growth of federal power or the actions of people outside government?

Use at least three parts of the story above. A good first answer may argue that the two forces depended on one another: organised people created pressure, while federal institutions could turn demands into national law—or refuse to enforce them.

What this first guide has not covered fully

This is a starting map, not the complete specification. You will still need detailed study of party politics and presidents; economic cycles; immigration; organised labour; Populism and Progressivism; both world wars; each Cold War administration; Korea and Vietnam; changing culture and living standards; and the experiences of different regions and communities.

The guide also introduces Native dispossession but does not yet teach it at the depth needed to understand continental expansion. It does not yet explain Alaska, tensions over Canada and the Monroe Doctrine; the Jazz Age, prohibition and women’s changing position need fuller coverage too. Nor does it provide the historical extracts and full essay practice required for the AQA Component 1 examination.

Keep exploring (optional)

Next, choose only one route:

• Race and citizenship: begin with Reconstruction, then trace the long struggle against Jim Crow.
• Economy and government: connect industrialisation, the Depression, the New Deal and the Great Society.
• America in the world: connect 1898, the world wars, the Cold War and Vietnam.
