What you'll learn
This topic examines the United States across five transformative decades, from the economic prosperity of the 1920s through the Great Depression, the Second World War, and the social upheavals of the postwar era. You'll explore how American society experienced both unprecedented opportunity and deep-rooted inequality, particularly affecting African Americans, women, immigrants, and the working class. This revision guide covers every aspect of the AQA specification, focusing on the economic, social, and political changes that shaped modern America.

Core concepts
The economic boom of the 1920s
The 1920s witnessed extraordinary economic expansion in the United States. Industrial production nearly doubled between 1921 and 1929, driven by several key factors:
Mass production techniques revolutionised manufacturing. Henry Ford's assembly line methods reduced the time to build a car from over 12 hours to just 93 minutes, making automobiles affordable for ordinary Americans. By 1929, there was one car for every five Americans, compared to one for every 43 in 1920.
New consumer industries emerged, particularly electrical goods. Refrigerators, vacuum cleaners, radios, and washing machines became widely available. Advertising and hire purchase schemes (buying on credit) encouraged consumption. By 1929, $7 billion worth of goods were sold on credit.
The stock market boom saw share prices rise dramatically. Many Americans invested their savings or bought shares on the margin (borrowing money to invest), believing prices would continue rising indefinitely. The Dow Jones Industrial Average increased from 63 points in 1921 to 381 in September 1929.
However, prosperity was unevenly distributed. Farmers struggled with overproduction and falling prices throughout the decade. African Americans, particularly in the rural South, remained in poverty. By 1929, 60% of American families earned less than $2,000 per year—the minimum considered necessary for a decent standard of living.
Social tensions in 1920s America
The decade experienced significant social conflict:
Immigration restriction reflected growing nativism. The 1924 Immigration Act established quotas heavily favouring northern Europeans whilst virtually excluding Asians and limiting southern and eastern Europeans. This reversed America's tradition as a nation welcoming immigrants.
Prohibition, enforced from 1920, aimed to reduce crime and improve morality but achieved the opposite. Speakeasies (illegal bars) proliferated—New York alone had an estimated 30,000 by 1929. Organised crime syndicates, like Al Capone's Chicago operation, earned millions from bootlegging. Prohibition was repealed in 1933, widely acknowledged as a failure.
Racial violence intensified. The revived Ku Klux Klan claimed 5 million members by 1925, targeting African Americans, Catholics, Jews, and immigrants. Race riots occurred in several cities. In the South, Jim Crow laws enforced strict segregation in schools, transport, restaurants, and public facilities. Lynchings continued with impunity.
The Scopes Trial (1925) highlighted tensions between religious fundamentalism and modern science. Teacher John Scopes was prosecuted for teaching evolution in Tennessee, illustrating the cultural divide between urban, liberal America and rural, conservative communities.
The Great Depression and the New Deal
The Wall Street Crash of October 1929 triggered America's worst economic catastrophe. Share prices collapsed—$30 billion in value was wiped out within a week. Banks failed by the thousands (over 5,000 between 1929 and 1932), destroying people's savings.
Unemployment reached approximately 25% by 1933—nearly 13 million people. Industrial production fell by 45%. Families lost their homes; Hoovervilles (shanty towns named mockingly after President Hoover) appeared in major cities. Farmers faced foreclosure as agricultural prices plummeted by 60%. The Dust Bowl of the mid-1930s forced thousands of farming families from Oklahoma, Kansas, and Texas to migrate west, seeking work in California.
President Franklin D. Roosevelt's New Deal (1933-1938) comprised three aims: Relief, Recovery, and Reform.
Relief measures provided immediate help:
- The Federal Emergency Relief Administration distributed $500 million to states for direct relief
- The Civilian Conservation Corps employed young men on environmental projects
- The Works Progress Administration created jobs building roads, schools, and public buildings
Recovery programmes aimed to restart the economy:
- The National Industrial Recovery Act established codes to regulate wages, prices, and working conditions
- The Agricultural Adjustment Act paid farmers to reduce production and raise prices
- The Tennessee Valley Authority built dams providing electricity and employment
Reform legislation sought lasting change:
- The Social Security Act (1935) introduced pensions and unemployment insurance
- The Wagner Act (1935) protected workers' rights to join trade unions
- The Fair Labor Standards Act (1938) established minimum wages and maximum working hours
The New Deal had mixed success. Unemployment fell to 14% by 1937 but rose again during the 1937-38 recession. Full recovery required the economic stimulus of the Second World War. However, the New Deal fundamentally changed Americans' expectations of federal government responsibility for economic welfare.
The impact of the Second World War
America's entry into war following Pearl Harbor (December 1941) transformed the economy and society.
Economic mobilisation ended the Depression. Unemployment virtually disappeared as 16 million Americans served in the armed forces and factories operated at full capacity producing war materials. Government spending increased dramatically, from $9 billion in 1939 to $98 billion in 1945.
Women's roles changed significantly. Over 6 million women entered the workforce, taking jobs previously reserved for men in munitions factories, shipyards, and aircraft plants. "Rosie the Riveter" became the symbol of female war workers. However, most women were pressured to return to domestic roles after 1945.
African Americans experienced both opportunity and discrimination. Over one million served in segregated military units. The Double V Campaign demanded victory over fascism abroad and racism at home. Northern factories recruited African American workers, accelerating the Great Migration from the South. Yet discrimination persisted—race riots occurred in Detroit (1943) and other cities over housing and employment tensions.
Japanese Americans faced severe persecution. Following Pearl Harbor, 120,000 Japanese Americans (two-thirds of them American citizens) were forcibly relocated to internment camps, losing homes and businesses despite no evidence of disloyalty.
Post-war prosperity and Cold War fears
The post-war era brought unprecedented prosperity for many Americans. The GI Bill provided veterans with subsidised mortgages, education, and business loans. Suburbanisation accelerated as white middle-class families moved to newly built suburbs. Car ownership, television, and consumer goods became widespread.
However, McCarthyism created an atmosphere of fear and suspicion from 1950-54. Senator Joseph McCarthy claimed communists had infiltrated government departments, making unsubstantiated accusations that ruined careers. The House Un-American Activities Committee investigated alleged communist influence in Hollywood, leading to the blacklisting of writers, directors, and actors. The execution of Julius and Ethel Rosenberg for espionage (1953) intensified Cold War paranoia.
Conformity characterised 1950s culture. Sociologists identified pressure to conform to middle-class values, suburban lifestyles, and traditional gender roles. Women were encouraged to focus on homemaking despite their wartime experience. This conformity provoked reaction in the 1960s.
The Civil Rights Movement
African Americans' struggle for equality intensified after 1945, challenging segregation and discrimination through various tactics:
Legal challenges achieved crucial victories. The NAACP's campaign led to Brown v. Board of Education (1954), where the Supreme Court ruled school segregation unconstitutional. However, implementation faced massive resistance, notably at Little Rock, Arkansas (1957), where President Eisenhower deployed federal troops to protect nine African American students integrating Central High School.
Direct action tactics escalated in the late 1950s. The Montgomery Bus Boycott (1955-56), triggered by Rosa Parks' arrest, demonstrated the economic power of African Americans. Martin Luther King Jr. emerged as the movement's most prominent leader, advocating non-violent protest based on Gandhi's principles.
The sit-in movement began in 1960 when four students refused to leave a segregated Greensboro lunch counter. The tactic spread rapidly across the South. Freedom Rides (1961) challenged segregation in interstate bus terminals, facing violent white opposition.
1963 proved pivotal. The Birmingham campaign used marches and boycotts to challenge segregation. Police Chief Bull Connor's violent response—using dogs and fire hoses against peaceful protesters, including children—shocked national television audiences. The March on Washington (August 1963) drew 250,000 people, where King delivered his "I Have a Dream" speech.
Legislation followed sustained pressure. The Civil Rights Act (1964) outlawed discrimination in public accommodations and employment. The Voting Rights Act (1965) banned literacy tests and other devices preventing African Americans from voting. These represented major achievements, though inequality persisted.
Black Power emerged from frustration with slow progress. Malcolm X advocated black self-reliance and, initially, separation rather than integration. Urban riots erupted in Watts, Los Angeles (1965), Detroit and Newark (1967), reflecting anger over poverty, unemployment, and police brutality in northern ghettos. The Black Panthers (founded 1966) combined militant rhetoric with community programmes.
King's assassination (April 1968) devastated the movement. Whilst legal segregation had ended, economic inequality, housing discrimination, and police violence remained unresolved issues.
The 1960s: protest and social change
President Lyndon B. Johnson's Great Society programmes (1964-68) expanded federal intervention:
- Medicare and Medicaid provided healthcare for the elderly and poor
- The War on Poverty created job training and community action programmes
- Federal education funding increased dramatically
- Environmental protection legislation was enacted
However, the Vietnam War increasingly dominated and divided America. American involvement escalated from 16,000 military advisers in 1963 to over 500,000 troops by 1968. The war cost 58,000 American lives and provoked massive opposition.
Anti-war protests grew steadily. Students organised teach-ins and demonstrations. The 1968 Democratic National Convention in Chicago witnessed violent clashes between protesters and police. Young men burned draft cards or fled to Canada to avoid conscription. The My Lai Massacre (1968), where American soldiers killed over 500 Vietnamese civilians, shocked the public when revealed in 1969.
Counterculture rejected mainstream American values. Young people embraced rock music, recreational drug use, sexual freedom, and alternative lifestyles. The hippie movement centred in San Francisco's Haight-Ashbury district. Woodstock festival (1969) attracted 400,000 people, symbolising the counterculture's peak.
Women's liberation challenged gender inequality. Betty Friedan's The Feminine Mystique (1963) critiqued the limits of suburban domesticity. The National Organization for Women (1966) campaigned for equal pay, abortion rights, and equal opportunities. The movement achieved the Equal Pay Act (1963) and Title VII of the Civil Rights Act prohibiting sex discrimination, though the Equal Rights Amendment failed to achieve ratification.
By 1973, America had transformed dramatically from the 1920s. Legal segregation had ended, federal government responsibility for social welfare was established, and traditional social norms had been challenged. However, racial inequality, poverty, and political divisions remained deeply embedded in American society.
Worked examples
Example 1: Explain why Prohibition failed (12 marks)
Question type: Explanation question requiring analysis of multiple causes
Model answer:
Prohibition failed primarily because it was impossible to enforce effectively. The United States had 18,700 miles of coastline and land borders, making it relatively easy for smugglers to import alcohol from Canada, Mexico, and the Caribbean. The Prohibition Bureau employed only 1,500 agents nationally—far too few to police such a vast area. Additionally, many agents were poorly paid and susceptible to bribery from wealthy bootleggers. This enforcement gap meant that alcohol remained readily available to those who wanted it.
Furthermore, Prohibition stimulated the growth of organised crime, which undermined respect for the law. Gangsters like Al Capone made enormous profits from illegal alcohol sales—Capone's organisation earned an estimated $60 million annually by 1927. These crime syndicates corrupted police officers, judges, and politicians, creating a cycle of lawlessness. The St Valentine's Day Massacre (1929), where Capone's men murdered seven rival gang members, exemplified the violence associated with Prohibition, turning public opinion against the policy.
Finally, Prohibition lacked consistent public support. Whilst rural, Protestant Americans generally supported it, urban populations and immigrant communities opposed the restrictions. The number of illegal speakeasies in cities—New York had approximately 30,000—demonstrated widespread defiance. As the Depression deepened after 1929, many Americans believed legalising alcohol would create jobs and tax revenue. By 1933, the combination of enforcement failure, crime wave, and changing public attitudes led to Prohibition's repeal through the 21st Amendment.
Examiner commentary: This answer achieves full marks by explaining three distinct reasons with specific supporting evidence, showing how each factor contributed to Prohibition's failure, and demonstrating clear understanding of causation.
Example 2: How useful are Sources A and B for an enquiry into the impact of the Great Depression on ordinary Americans? (8 marks)
Question type: Source utility question
Approach:
- Evaluate content (what the source reveals)
- Evaluate provenance (nature, origin, purpose—NOP)
- Relate to contextual knowledge
- Address both sources with balanced coverage
Model structure:
Source A is useful because it shows [specific detail] which reveals [what this tells us about the enquiry focus]. This is reinforced by my knowledge that [contextual detail]. However, its usefulness is limited because [provenance issue—e.g., it only shows one perspective/moment in time/government propaganda].
Source B is useful in a different way because [specific detail] which demonstrates [connection to enquiry]. The fact it is [nature—photograph/speech/poster] created by [origin] in [date] for [purpose] means [how this affects reliability/usefulness]. My knowledge that [context] supports/challenges what the source shows.
Together, the sources are useful for this enquiry because they show [synthesis point], though they don't reveal [limitation of sources collectively].
Common mistakes and how to avoid them
Confusing chronology: Students often muddle the order of events, particularly mixing up 1920s prosperity with 1930s Depression. Create a clear timeline noting key dates: 1929 (Wall Street Crash), 1933 (New Deal begins/Prohibition ends), 1941 (Pearl Harbor), 1954 (Brown decision), 1964-65 (Civil Rights and Voting Rights Acts).
Oversimplifying the New Deal: Avoid simply stating "the New Deal solved the Depression." Instead, evaluate its mixed success—it provided relief and reformed the economy but didn't restore full employment until wartime. Distinguish between First New Deal (1933-34) and Second New Deal (1935-38).
Treating African Americans' experience as uniform: Recognise regional differences (Southern segregation vs Northern discrimination), class divisions, and changing tactics (NAACP legal strategy vs SNCC direct action vs Black Power militancy). Avoid suggesting the Civil Rights Movement ended all inequality.
Ignoring women and other groups: Examiners expect coverage of women, Native Americans, Hispanic Americans, and immigrants, not just African Americans. Questions about "opportunity and inequality" require you to discuss multiple groups.
Source questions without provenance: In utility and reliability questions, always analyse Nature, Origin, and Purpose—not just what the source says. A government poster has different usefulness than a private diary entry.
Narrative answers instead of analysis: Avoid simply telling the story. Every paragraph should answer the specific question using evidence. Use analytical phrases: "This caused...", "As a consequence...", "This suggests...", "However...".
Exam technique for "America, 1920–1973: Opportunity and Inequality"
Master command words: "Explain why" requires causes with explanatory links (8-12 marks); "How far do you agree" demands a balanced argument evaluating an interpretation (16 marks); "How useful" needs content analysis plus provenance evaluation (8 marks); "Describe" requires factual detail only (4 marks).
Structure extended answers carefully: For 16-mark essays, write an introduction stating your argument, 3-4 analytical paragraphs each making a distinct point with specific evidence, and a conclusion reaching a substantiated judgement. Avoid narrative—every paragraph must advance your argument.
Use precise evidence: Instead of vague statements like "many people were unemployed," write "unemployment reached approximately 25% by 1933—nearly 13 million workers." Specific statistics, names, dates, and legislation strengthen answers significantly.
Balance your judgements: For evaluation questions, address both sides before reaching a conclusion. Use phrases like "On one hand... However..." or "Whilst X was significant, Y proved more important because..." Show you can weigh different factors rather than simply agreeing or disagreeing.
Quick revision summary
America experienced dramatic transformation between 1920 and 1973. The 1920s economic boom created prosperity but excluded many groups and ended in the 1929 Wall Street Crash. The Great Depression devastated the economy until Roosevelt's New Deal programmes provided relief and reform, though full recovery required wartime mobilisation. Post-1945 prosperity coexisted with McCarthyism and conformity. The Civil Rights Movement challenged segregation through legal battles, non-violent protest, and eventually Black Power militancy, achieving major legislation but not full equality. The 1960s witnessed Johnson's Great Society, Vietnam War opposition, counterculture rebellion, and women's liberation, fundamentally challenging traditional American society.
