7.6 World War I: Home Front

While American soldiers fought abroad during World War I, the United States went through major social and economic changes at home. The war effort required expanded government management of the economy, restricted civil liberties, altered migration patterns, and changed the role of women and minorities in the workforce.

What to Know About World War I

• The Espionage and Sedition Acts restricted wartime speech, and the Supreme Court upheld the Espionage Act in Schenck v. United States.
• Wilson created wartime agencies to manage production and food supplies, while the federal government took direct control of the railroads.
• Union membership grew during the war, and about 1 million women entered the workforce; women's wartime experiences helped build momentum for the 19th Amendment.
• Factory opportunities in the North and West and racism in the South drove the Great Migration of African Americans, which continued after the war; migrants gained new opportunities but still faced discrimination in their new homes. European immigration virtually stopped during the war.
• George Creel's Committee on Public Information used pamphlets, posters, and other media to build support for the war.
• Fear of communism fueled the First Red Scare after the war, including Palmer Raids against suspected radicals and warrantless arrests and deportations of immigrants.

Wartime Restrictions on Civil Liberties

The urgency of war led to government restrictions on free speech and the persecution of those perceived as disloyal. Americans who opposed the war found themselves facing both legal punishment and mob violence.

Anti-German Sentiment

Americans of German descent, the largest immigrant group in the United States at the time, became targets of suspicion and harassment:

• German language instruction was removed from many schools
• German foods were renamed (sauerkraut became "liberty cabbage")
• German music was banned from concert halls
• German books were removed from libraries or even burned
• German-Americans were forced to buy war bonds to prove their loyalty
• Mobs sometimes attacked those with German names or accents

The Espionage and Sedition Acts

The Wilson administration enacted legislation that severely restricted free speech:

• The Espionage Act (1917) made it illegal to interfere with military operations or recruitment
• The Sedition Act (1918) prohibited "disloyal, profane, scurrilous, or abusive language" about the government, flag, or armed forces

These laws were used to silence critics of the war, including:

• Eugene V. Debs, Socialist Party leader, who was sentenced to 10 years in prison for an antiwar speech
• Over 1,500 others who were arrested for criticizing the war effort
• Newspapers and magazines that were censored or shut down for opposing the war

Supreme Court Limitations on Free Speech

In a landmark case, Schenck v. United States (1919), the Supreme Court unanimously upheld the constitutionality of the Espionage Act. Justice Oliver Wendell Holmes introduced the "clear and present danger" test for limiting free speech, writing that the First Amendment would not protect someone "falsely shouting fire in a theatre and causing a panic."

This decision established that the government could restrict speech that presented a clear danger to national security during wartime, severely limiting Americans' First Amendment protections until later court decisions modified this standard.

Government Management of the Economy

The war required a coordinated national effort to supply both American and Allied forces. President Wilson created several temporary agencies to manage resources, production, and labor relations:

War Industries Board

Headed by financier Bernard Baruch, the War Industries Board became the most powerful of the wartime agencies:

• Set production priorities for factories
• Allocated raw materials to priority industries
• Fixed prices on many goods
• Standardized products to increase efficiency
• Coordinated purchasing among government agencies

Though the board lacked formal enforcement powers, most industries cooperated voluntarily, recognizing that government contracts offered substantial profits.

Food Administration

Led by future president Herbert Hoover, the Food Administration managed the nation's food supply:

• Encouraged voluntary conservation with slogans like "Food will win the war"
• Promoted "Wheatless Mondays" and "Meatless Tuesdays"
• Established gardens in yards and vacant lots ("victory gardens")
• Set price controls on staple foods
• Increased agricultural production through guaranteed prices to farmers

These efforts were remarkably successful—American food exports to Allies tripled during the war without requiring strict rationing at home.

Fuel Administration

This agency managed coal and oil resources:

• Implemented "heatless Mondays" in factories
• Established daylight saving time to conserve electricity
• Regulated fuel distribution to prioritize wartime industries

Railroad Administration

The government took direct control of the nation's railroads from December 1917 until March 1920:

• Standardized equipment and procedures
• Coordinated schedules to eliminate competition
• Prioritized military shipments
• Improved efficiency by routing traffic more logically

This wartime experiment with nationalization ultimately led to the Transportation Act of 1920, which returned railroads to private ownership but under increased federal regulation.

Labor and Industrial Relations

The war created labor shortages and increased demand for industrial production, strengthening workers' bargaining position:

National War Labor Board

Established in 1918 and co-chaired by former President William Howard Taft:

• Mediated labor disputes to prevent strikes
• Established the 8-hour workday in many industries
• Recognized workers' right to organize unions
• Required equal pay for women doing the same work as men

Union membership grew from about 2.7 million in 1916 to more than 4 million by 1919.

Women in the Workforce

With men leaving for military service, women entered new occupations:

• Took jobs in munitions plants, shipyards, and steel mills
• Served as streetcar conductors, railroad workers, and office clerks
• Worked as nurses and clerical staff for the military
• Joined the military as yeomen (Navy) or in the Army Nurse Corps

About 1 million women entered the workforce during the war. While most were expected to return to domestic roles after the war, their experiences helped build momentum for the women's suffrage movement, which achieved victory with the ratification of the 19th Amendment in 1920.

Migration Patterns and Demographic Changes

The war dramatically affected the movement of people within the United States:

The Great Migration

The most significant population shift was the Great Migration of African Americans from the rural South to industrial cities in the North and Midwest:

• Labor shortages and higher wages in Northern factories created economic opportunities
• Southern racism, Jim Crow laws, and lynchings provided powerful push factors
• Between 1916 and 1920, over 500,000 African Americans moved north
• Cities like Chicago, Detroit, Cleveland, and New York saw their Black populations grow dramatically

This mass migration changed the racial composition of northern cities and laid the groundwork for the Harlem Renaissance and civil rights activism in the coming decades.

New Limits on Immigration

European immigration, which had reached record levels before the war, virtually stopped during the conflict. This led to:

• Increased opportunities for native-born workers and internal migrants
• Growing nativist sentiment against immigrants, especially those from southern and eastern Europe
• Mounting fears of foreign radicals and revolutionaries
• Pressure for immigration restriction, which would culminate in the quota laws of the 1920s
• Nativist campaigns also raised new barriers to Asian immigration, so restriction targeted Asians as well as southern and eastern Europeans

Wartime Housing Crisis

The sudden influx of workers into industrial centers created severe housing shortages:

• Workers often lived in overcrowded, substandard housing
• Racial tensions increased as groups competed for limited housing
• The government built some emergency housing for workers in shipbuilding and munitions centers

Propaganda and Public Opinion

The government worked to shape public opinion through the Committee on Public Information (CPI), headed by journalist George Creel:

• Distributed millions of pamphlets, posters, and press releases
• Recruited 75,000 "Four-Minute Men" to deliver patriotic speeches in theaters
• Produced films promoting the war effort
• Coordinated with advertising agencies to create iconic posters (like Uncle Sam's "I Want YOU")
• Encouraged reporting that portrayed Germans as brutal enemies

The CPI's efforts helped transform a reluctant public into enthusiastic supporters of the war and demonstrated the power of modern mass media to shape public opinion.

The Red Scare and Postwar Tensions

As the war ended, fear of communism replaced fear of Germany, leading to the First Red Scare (1919-1920):

• The Bolshevik Revolution in Russia (1917) sparked fears of communist revolution in America
• A series of mail bombs targeting government officials in 1919 intensified these fears
• Attorney General A. Mitchell Palmer conducted raids against suspected radicals (the "Palmer Raids")
• Thousands of immigrants were arrested without warrants, and hundreds were deported
• Labor unions faced accusations of radical influence, undermining their wartime gains

This period of anti-communist hysteria foreshadowed the more extensive Second Red Scare that would occur after World War II.

Legacy of the World War I Home Front

The home front experience during World War I left lasting marks on American society. The expansion of federal power, restrictions on civil liberties, changing demographics, and new roles for women and minorities all contributed to the social tensions of the 1920s. The war accelerated trends already underway in American society—urbanization, industrialization, government regulation, and changing gender and racial dynamics—and set the stage for further transformations in the decades to come.
