Depth Study: The USA, 1919–41

What you'll learn

This depth study examines the dramatic transformation of the United States between the two world wars. You'll explore the economic boom and social changes of the 1920s, the catastrophic Wall Street Crash, the hardships of the Great Depression, and Franklin D. Roosevelt's New Deal programmes designed to rescue American capitalism. Understanding causation, consequence, and the effectiveness of government responses is essential for success in this paper.

Core concepts

The economic boom of the 1920s

The United States experienced unprecedented prosperity following the First World War, though this prosperity was neither universal nor sustainable.

Key factors driving economic growth:

• Mass production techniques pioneered by Henry Ford reduced manufacturing costs and made consumer goods affordable
• The motor industry became the backbone of the economy, stimulating steel, glass, rubber and road construction sectors
• New electrical consumer goods (radios, refrigerators, vacuum cleaners) created mass markets
• Hire purchase (instalment credit) enabled ordinary Americans to buy expensive items by paying in instalments
• Republican governments pursued low taxation and minimal regulation, encouraging business expansion
• High tariffs protected American manufacturers from foreign competition

Limitations of prosperity:

• Agriculture remained depressed throughout the decade due to overproduction and falling prices
• Traditional industries (coal, textiles) struggled against competition
• African Americans and recent immigrants experienced persistent poverty and discrimination
• Wealth inequality increased dramatically—60% of families earned less than the $2,000 needed for basic necessities

Social developments and tensions in the 1920s

The decade witnessed fundamental conflicts between traditional and modern values.

Prohibition (1920–1933):

• The 18th Amendment banned alcohol to reduce crime and immorality
• Bootlegging (illegal alcohol production and distribution) became a massive criminal enterprise
• Speakeasies (illegal drinking establishments) proliferated in cities
• Organised crime figures like Al Capone earned millions through illegal alcohol sales
• Prohibition proved unenforceable and was repealed by the 21st Amendment in 1933
• Federal agents destroyed illegal stills but corruption among officials undermined enforcement

Immigration restrictions:

• The 1921 Emergency Quota Act and 1924 Immigration Act severely limited immigration, especially from Southern and Eastern Europe
• Immigration fell from 800,000 annually (1920) to 150,000 (1929)
• Motivated by fears about preserving "American" culture and protecting jobs

Racial tensions:

• The Ku Klux Klan revived, claiming 5 million members by 1925, targeting African Americans, Catholics, Jews and immigrants
• The 1921 Tulsa Race Massacre destroyed a prosperous black community
• The "Great Migration" saw African Americans move from Southern states to Northern industrial cities seeking employment and escaping Jim Crow segregation

Cultural changes:

• Flappers represented young women who challenged traditional behaviour through shorter skirts, bobbed hair, smoking and dancing
• Jazz music emerged from African American communities, symbolising the era
• Cinema became mass entertainment—100 million cinema tickets sold weekly by 1929
• The Scopes Trial (1925) highlighted tensions between religious fundamentalism and modern science

The Wall Street Crash and its causes (1929)

The dramatic stock market collapse of October 1929 ended the boom and triggered worldwide depression.

Underlying economic weaknesses:

• Overproduction meant supply exceeded demand across industries
• Unequal wealth distribution limited consumer purchasing power
• Excessive stock market speculation created inflated share prices disconnected from company values
• Many shares purchased "on the margin" (borrowing most of the purchase price)
• Weakness in agriculture and traditional industries undermined the broader economy
• International debt problems—European nations struggled to repay American loans whilst paying war reparations

The Crash:

• Share prices peaked in September 1929 then began falling
• 24th October ("Black Thursday")—panic selling began
• 29th October ("Black Tuesday")—16 million shares sold; prices collapsed
• Investors who bought on the margin faced ruin
• Banks that loaned money for speculation lost heavily
• By 1932, share values had fallen to 20% of their 1929 levels

The Great Depression (1929–1933)

Economic collapse brought unprecedented hardship to millions of Americans.

Economic consequences:

• Industrial production fell 45% between 1929–1932
• Unemployment rose from 1.5 million (1929) to 13 million (1933)—approximately 25% of the workforce
• 5,000 banks collapsed (1929–1933), destroying depositors' savings
• Average wages fell 60%
• International trade collapsed as nations imposed protective tariffs
• Farm income dropped 60% as agricultural prices plummeted

Social impact:

• Homelessness increased dramatically—shanty towns called "Hoovervilles" appeared in major cities, named mockingly after President Hoover
• Malnutrition and disease increased, though surprisingly few starvation deaths occurred
• 250,000 young people became homeless drifters
• Marriage and birth rates declined sharply
• The Dust Bowl displaced 300,000 farming families from Oklahoma, Kansas and Texas

Hoover's response:

• President Herbert Hoover initially believed recovery would occur naturally
• He maintained faith in laissez-faire principles and "rugged individualism"
• Rejected direct federal relief (welfare payments) as undermining American character
• Eventually established the Reconstruction Finance Corporation (1932) lending $2 billion to banks and businesses
• His limited interventions proved inadequate
• The 1932 Bonus Army incident—forcible removal of 17,000 war veterans demanding early payment of bonuses—destroyed Hoover's remaining popularity

Roosevelt and the First New Deal (1933–1935)

Franklin D. Roosevelt won the 1932 presidential election promising a "New Deal" for Americans. His immediate priority was restoring confidence and providing relief.

Emergency measures (First Hundred Days, March–June 1933):

• Declared a four-day "bank holiday" to stop panic withdrawals
• Emergency Banking Act inspected banks; only sound institutions reopened
• Ended Prohibition to raise tax revenue and create jobs
• Twenty major laws passed within 100 days

Key First New Deal agencies:

Relief programmes:

• Civilian Conservation Corps (CCC) employed 2.5 million young men in environmental projects
• Federal Emergency Relief Administration (FERA) provided $500 million in direct relief to states
• Civil Works Administration (CWA) created 4 million temporary jobs building roads and public facilities

Recovery programmes:

• Agricultural Adjustment Administration (AAA) paid farmers to reduce production, raising prices
• National Industrial Recovery Act established the National Recovery Administration (NRA) setting wages, prices and production codes
• Public Works Administration (PWA) funded major construction projects (dams, bridges, schools)

Reform programmes:

• Tennessee Valley Authority (TVA) brought electricity, flood control and development to seven impoverished states
• Truth in Securities Act regulated stock markets to prevent fraud

Communications:

• Roosevelt's "fireside chats" (radio broadcasts) explained policies directly to citizens, building support and confidence

The Second New Deal (1935–1938) and opposition

After initial success, Roosevelt faced criticism from both left and right. The Second New Deal introduced more radical reforms.

Key Second New Deal measures:

• Works Progress Administration (WPA) employed 8 million in construction, arts and theatre projects
• Social Security Act (1935) established unemployment insurance, old-age pensions and support for disabled—America's first welfare system
• Wagner Act (1935) guaranteed workers' rights to join trade unions and engage in collective bargaining
• Fair Labor Standards Act (1938) established minimum wages and maximum working hours

Opposition to the New Deal:

From the right:

• Republicans and business leaders attacked Roosevelt as a "communist" undermining free enterprise
• The Supreme Court ruled the NRA (1935) and original AAA (1936) unconstitutional for exceeding federal powers
• Roosevelt attempted "court packing" (adding sympathetic judges) in 1937 but Congress rejected this

From the left:

• Huey Long's "Share Our Wealth" movement advocated confiscating fortunes over $5 million
• Father Coughlin, a radio priest, attracted millions with anti-Roosevelt rhetoric
• Some argued the New Deal didn't go far enough in redistributing wealth

Continued problems:

• The 1937–1938 recession occurred when Roosevelt reduced government spending
• Unemployment remained at 10 million in 1939
• Full recovery only came with wartime production after 1941

Evaluating the New Deal's effectiveness

The New Deal remains controversial among historians regarding its success.

Arguments for success:

• Prevented total economic collapse and restored confidence in capitalism
• Unemployment fell from 25% (1933) to 14% (1940)
• Banking system stabilized—no major bank failures after 1933
• Infrastructure projects (dams, roads, schools) provided lasting benefits
• Social Security created a safety net protecting vulnerable Americans
• Strengthened trade unions and improved working conditions
• The TVA transformed one of America's poorest regions
• Demonstrated government could actively address economic problems

Arguments for limited success:

• Failed to achieve full economic recovery—only war production ended the Depression
• National debt trebled from $22 billion to $40 billion
• The Supreme Court blocked key programmes
• African Americans and women received limited benefits—discrimination persisted
• Some programmes proved wasteful or ineffective
• Agricultural policies actually increased rural poverty by displacing tenant farmers
• Conservative opposition prevented more radical reforms

Consensus view:

Most historians acknowledge the New Deal provided essential relief and prevented social breakdown, reformed capitalism to make it more stable, but didn't end the Depression. Its psychological impact—restoring hope and demonstrating government responsibility for citizens' welfare—proved as important as economic measures.

Worked examples

Example 1: Four-mark "describe" question

Describe the key features of Prohibition in the 1920s. [4 marks]

Model answer:

The 18th Amendment (1920) banned the manufacture, transportation and sale of alcohol across the United States. However, enforcement proved extremely difficult, with illegal "speakeasies" becoming common in cities and "bootleggers" smuggling alcohol from Canada and the Caribbean. Organised crime groups, particularly Al Capone's operation in Chicago, earned enormous profits from the illegal alcohol trade, leading to violent gang warfare. Prohibition ultimately failed and was repealed in 1933 through the 21st Amendment.

Mark scheme guidance: Award 1 mark per distinct, relevant point. Accurate detail about causes, implementation, consequences or ending expected. Maximum 4 marks.

Example 2: Six-mark "explain why" question

Explain why the Wall Street Crash occurred in 1929. [6 marks]

Model answer:

The Wall Street Crash resulted from excessive speculation in the stock market throughout the 1920s. Many Americans bought shares hoping to sell them quickly at profit rather than for long-term investment. Banks loaned money for speculation, and people purchased "on the margin," borrowing up to 90% of the share price. This created artificially inflated prices disconnected from companies' real value.

Underlying economic weaknesses also contributed. Overproduction meant industries produced more goods than consumers could afford, whilst unequal wealth distribution limited purchasing power—60% of American families lived below the poverty line. When confidence faltered in October 1929, panic selling began, with prices collapsing on "Black Thursday" (24th October) and "Black Tuesday" (29th October). Those who bought on the margin couldn't repay loans, and banks failed, triggering economic catastrophe.

Mark scheme guidance: Award marks for identifying causes (2–3 marks) and explaining how they led to the Crash (3–4 marks). Top level requires explicit links between causes and consequences. Maximum 6 marks.

Example 3: Ten-mark "how far do you agree" question

"The New Deal successfully solved America's economic problems." How far do you agree with this statement? Explain your answer. [10 marks]

Model answer:

The New Deal achieved significant successes but didn't completely solve America's economic problems. Roosevelt's immediate banking reforms prevented total financial collapse—the bank holiday and Emergency Banking Act stabilised the system, and no major banks failed after 1933. The various alphabet agencies provided relief to millions through employment programmes like the CCC and WPA, which gave jobs to over 10 million Americans, whilst the Social Security Act created a welfare safety net.

Infrastructure projects brought lasting benefits. The TVA transformed the Tennessee Valley through electrification and flood control, whilst the PWA built schools, hospitals and bridges still used today. Psychologically, Roosevelt's fireside chats restored confidence when Americans desperately needed hope.

However, the New Deal didn't end the Depression. Unemployment remained at 10 million in 1939—approximately 17% of the workforce. Only the wartime production boom after 1941 achieved full employment. The Supreme Court blocked key programmes like the NRA and original AAA, limiting effectiveness. Government debt trebled from $22 billion to $40 billion, and the 1937–1938 recession showed the economy remained fragile. Furthermore, African Americans, women and agricultural labourers received limited benefits, and wealth inequality persisted.

Overall, whilst the New Deal prevented catastrophe, reformed capitalism and provided essential relief, it didn't fully solve America's economic problems, which required wartime demand to achieve complete recovery.

Mark scheme guidance: Level 1 (1–3 marks): Simple statements. Level 2 (4–6 marks): Describes New Deal measures or identifies success/failure. Level 3 (7–8 marks): Explains both successes and limitations. Level 4 (9–10 marks): Sustained analysis with supported judgement weighing evidence on both sides. Maximum 10 marks.

Common mistakes and how to avoid them

• Confusing dates and chronology — clearly distinguish between the 1920s boom, the 1929 Crash, Hoover's presidency (1929–1933), and Roosevelt's New Deal (1933–1941). Create a timeline to visualise the sequence.

• Describing without explaining — questions asking "why" or "explain" require you to show causation, not just list facts. Use connectives: "This led to...", "As a consequence...", "This caused... because..."

• Ignoring the question focus — if asked about economic problems, don't write extensively about social issues. Tailor every paragraph to the specific question.

• One-sided arguments — 10-mark evaluation questions require balanced analysis. Present evidence for both perspectives before reaching a supported judgement.

• Vague generalizations — avoid phrases like "many people" or "things got better." Use specific statistics: "unemployment fell from 13 million (1933) to 8 million (1937)" demonstrates precise knowledge.

• Mixing up alphabet agencies — learn the specific purpose of key agencies (CCC, TVA, AAA, WPA, NRA). Examiners expect accurate details about at least two or three major programmes.

Exam technique for "Depth Study: The USA, 1919–41"

• Command words matter intensely: "Describe" requires characteristics or features (4 marks). "Explain why" requires causes with developed reasoning (6 marks). "How far/How important" requires balanced evaluation with a judgement (10 marks). Adjust your approach accordingly.

• Structure 10-mark answers carefully: Introduction stating your argument, two paragraphs supporting the statement, two paragraphs challenging it, conclusion with clear judgement. Each paragraph needs specific evidence (names, dates, statistics).

• Use the mark allocation as a time guide: Spend approximately 5 minutes on 4-mark questions, 8 minutes on 6-mark questions, and 15 minutes on 10-mark questions. This leaves time for checking.

• Support every point with evidence: Don't write "Roosevelt helped farmers." Instead write: "The Agricultural Adjustment Administration paid farmers to reduce production, which raised agricultural prices by 50% between 1933–1935, increasing farm income."

Quick revision summary

The USA experienced dramatic changes between 1919–1941. The 1920s boom, driven by mass production and consumerism, masked underlying economic weaknesses and social tensions including Prohibition and racial conflict. The 1929 Wall Street Crash resulted from speculation and overproduction, triggering the catastrophic Great Depression with 25% unemployment. Hoover's laissez-faire response proved inadequate. Roosevelt's New Deal (1933–1938) provided relief through alphabet agencies, recovery through public works, and reform through Social Security and labour legislation. Whilst the New Deal prevented total collapse and reformed capitalism, full recovery required wartime production. Understanding causation, evaluating effectiveness, and supporting arguments with specific evidence ensures examination success.
