Topic 7.8 Notes – 1920s: Cultural and Political Controversies
Why the 1920s Became a Fight Over American Identity
In 1920, for the first time, most Americans lived in cities. Urban life brought jobs, department stores, offices, movies, radio, automobiles, and national advertising. It also made women, immigrants, and internal migrants more visible in public life.
World War I sharpened tensions. Wartime nationalism, the First Red Scare, labor strikes, and bomb scares made many people fear that change meant disorder. That is why so many 1920s debates connect. They were all arguments over who counted as American and what values government should enforce.
- Modernists tended to accept urban life, science, consumer culture, looser gender norms, and artistic experimentation.
- Traditionalists defended Protestant morality, rural and small-town values, older gender roles, and racial and ethnic hierarchy.
Migration and Urban Culture
Cities pulled in many groups at once. Immigrants came for work. African Americans left the South. Rural whites moved to industrial centers. Women found more jobs in clerical work, retail, teaching, nursing, and factories. Ethnic neighborhoods helped newcomers keep language, religion, newspapers, foodways, and political networks.
The Great Migration
African Americans moved north and midwest because the South offered Jim Crow, disfranchisement, racial violence, poor schools, and limited jobs. Northern cities offered factory work and somewhat greater freedom.
- Major destinations included New York, Chicago, Detroit, Cleveland, and Philadelphia.
- Life in the North still meant segregation, restrictive covenants, job discrimination, and white hostility.
- Red Summer of 1919 showed how racial tension exploded into violence.
- In Tulsa, 1921, white mobs destroyed Greenwood, known as “Black Wall Street.”
Black urban responses
The new Black urban culture produced different kinds of resistance and pride. Aaron Douglas's art captured that mix of struggle, modern city life, and hope for the future.
- Harlem Renaissance
Alain Locke’s The New Negro celebrated a “New Negro” identity built on racial pride and self-definition. Writers and artists included Langston Hughes, Claude McKay, Zora Neale Hurston, Countee Cullen, and Aaron Douglas. Musicians like Duke Ellington, Louis Armstrong, and Bessie Smith spread jazz and blues through clubs, records, and radio.
- Legal activism
The NAACP fought lynching. The Dyer Anti-Lynching Bill passed the House in 1922 but died in the Senate.
- Black nationalism
Marcus Garvey and the UNIA pushed Black pride, economic self-sufficiency, Pan-Africanism, and the Black Star Line. This differed from the NAACP’s integrationist approach.

Nativism and Immigration Restriction
Fear of immigrants grew out of the Bolshevik Revolution, strikes, anarchist bombings, and the Palmer Raids. Nativists mixed anti-radical fear with eugenics and “scientific racism,” targeting southern and eastern Europeans, Catholics, Jews, and Asians.
| Law or example | What it did |
|---|---|
| Emergency Quota Act (1921) | Set quotas at 3% of each nationality already in the U.S. based on the 1910 census |
| Immigration Act of 1924 | Also called Johnson-Reed Act or National Origins Act; cut quotas to 2% based on the 1890 census |
| Asian exclusion | Effectively barred Japanese immigration and reinforced older Asian exclusion |
| Western Hemisphere | No quotas, so Mexican labor migration continued |
| Border Patrol (1924) | Created to police borders |
| Indian Citizenship Act (1924) | Granted citizenship to Native Americans, but not equal rights or guaranteed voting access |
The quota map here makes the pattern visible. Northern and western Europe received larger allotments, and much of Asia faced exclusion under the new system.

Immigration quotas under the 1924 law
Sacco and Vanzetti became symbols of anti-immigrant and anti-radical prejudice. The second Ku Klux Klan promoted “100 percent Americanism,” white Protestant supremacy, Prohibition, and anti-Black, anti-Catholic, antisemitic, and anti-immigrant politics. It had national power, especially in Indiana and Oregon, before scandals like the D. C. Stephenson case weakened it.
Moral and Cultural Controversies
Prohibition came from temperance reform, Progressivism, Protestant moral campaigns, and anti-immigrant feeling. The Eighteenth Amendment and Volstead Act tried to ban alcohol, but speakeasies, bootlegging, organized crime, corruption, and weak enforcement followed. Al Capone became the best-known example.
Religion and science clashed in the Scopes Trial of 1925. Tennessee’s Butler Act banned teaching evolution. John T. Scopes was prosecuted, with Clarence Darrow for the defense and William Jennings Bryan for the prosecution. Scopes was convicted. The larger impact was cultural because the press mocked fundamentalism nationwide.
Women’s roles were changing too. The Nineteenth Amendment gave women the vote. The flapper symbolized youth, consumption, and sexual independence, though most women did not live that lifestyle. Many women worked in clerical and service jobs but still earned less and hit barriers. Alice Paul proposed the Equal Rights Amendment in 1923, dividing reformers over equal treatment versus protective labor laws. Margaret Sanger pushed birth control activism.
Writers also criticized modern America. Ernest Hemingway and F. Scott Fitzgerald represented the Lost Generation. Sinclair Lewis’s Main Street and Babbitt, along with Fitzgerald’s The Great Gatsby, attacked materialism, conformity, and the emptiness under prosperity.
Why These Conflicts Matter
The 1920s expanded freedom and visibility for some people, especially in cities, while producing organized backlash. Government enforced cultural values through immigration quotas, Prohibition, anti-evolution laws, and unequal citizenship.
The 1928 election made the split obvious. Herbert Hoover faced Al Smith, whose Catholic faith, immigrant background, urban identity, and anti-Prohibition stance made him a target for rural and Protestant voters. The decade was both a Jazz Age and an age of exclusion.
