5.2 World War I & the Home Front

From Neutrality to Entry

When war erupted in Europe in 1914, President Woodrow Wilson urged Americans to be 'neutral in fact as well as in name.' The U.S. tried to trade with both sides, but a chain of events pulled it toward the Allies. Regents items commonly ask you to sequence these causes:

1. Submarine warfare: German U-boats attacked ships in the Atlantic. The sinking of the British liner Lusitania in 1915 killed 128 Americans and outraged U.S. opinion.
2. Economic ties: U.S. banks and factories were deeply invested in Allied trade and loans.
3. Unrestricted submarine warfare: in early 1917 Germany resumed sinking all ships in the war zone, including neutral American vessels.
4. The Zimmermann Telegram (1917): a secret German message urging Mexico to attack the U.S. in exchange for recovering Texas, New Mexico, and Arizona; its interception inflamed public anger.

Wilson asked Congress to declare war in April 1917 so the world could be 'made safe for democracy.' A key point: the immediate trigger was submarine warfare and the Zimmermann Telegram, not a direct attack on U.S. soil.

Wilson's Fourteen Points

In January 1918 Wilson outlined the Fourteen Points, his blueprint for a just peace. Recurring elements tested on the exam include:

• Open diplomacy (no secret treaties) and freedom of the seas
• Reduced arms and lowered trade barriers
• National self-determination for various peoples
• A League of Nations for collective security

At the 1919 Paris Peace Conference, Allied leaders imposed a harsher Treaty of Versailles, forcing Germany to accept a 'war guilt' clause and heavy reparations. Wilson's greatest victory was inserting the League of Nations, which became the central fight back home.

The Home Front

Mobilizing for total war expanded federal power over the economy and society.

Women took factory and clerical jobs, strengthening the argument for suffrage; the Nineteenth Amendment (1920) followed soon after.

Civil Liberties in Wartime

Congress passed the Espionage Act (1917) and Sedition Act (1918), making it a crime to interfere with the draft or to speak disloyally about the government or war. Socialist leader Eugene V. Debs was imprisoned for an anti-war speech. In Schenck v. United States (1919), the Supreme Court unanimously upheld a conviction for distributing anti-draft leaflets, ruling that speech creating a 'clear and present danger' is not protected, especially in wartime. This case is a cornerstone example of how national security can limit First Amendment freedoms, a theme the Civic Literacy Essay often revisits (compare with post-9/11 debates).

Rejecting the League of Nations

Back home, the Senate had to ratify the treaty. Opposition split into groups:

• Irreconcilables opposed the League entirely.
• Reservationists, led by Senator Henry Cabot Lodge, would accept the League only with changes, especially to Article X, the collective-security clause that might commit the U.S. to foreign wars without a congressional vote.

Wilson refused to compromise and collapsed during a national speaking tour. The Senate rejected the Treaty of Versailles, so the United States never joined the League of Nations. This outcome reflected a return toward isolationism and showed the constitutional principle of checks and balances: the Senate's treaty-ratification power (a two-thirds vote) checked the president's diplomacy.

The First Red Scare

Postwar fears of communism, fueled by the 1917 Russian Revolution, labor strikes, and anarchist bombings, produced the First Red Scare (1919-1920). Attorney General A. Mitchell Palmer directed the Palmer Raids, arresting and deporting thousands of suspected radicals and immigrants, often without due process. The Red Scare fed the anti-immigrant mood that led to the restrictive quota laws of the 1920s. On the exam, the Red Scare, Schenck, and the Espionage and Sedition Acts are best used together as examples of how wartime and postwar fear can erode civil liberties.

Common Exam Traps

Watch these recurring distinctions:

• Trigger for entry: World War I began for the U.S. with submarine warfare and the Zimmermann Telegram, not a direct attack on U.S. soil (contrast with Pearl Harbor in 1941). An answer citing an attack on American territory is wrong for 1917.
• Fourteen Points vs. Versailles: Wilson's plan was idealistic and lenient; the actual Treaty of Versailles was harsh toward Germany (war-guilt clause, reparations). Do not treat them as identical.
• Why the U.S. stayed out of the League: the cause was the Senate's rejection of the treaty, an exercise of checks and balances, not a presidential veto (presidents do not veto treaties) and not exclusion by the League.
• Schenck's standard: it upheld speech limits ('clear and present danger'); it did not strike the wartime laws down.

Worked comparison: a common Civic Literacy item links World War I civil-liberties restrictions (Espionage Act, Schenck, Palmer Raids) with post-9/11 measures (USA PATRIOT Act, surveillance). The pattern to state is that the federal government has repeatedly expanded security powers and limited liberties during national crises, then debated those limits afterward, exactly the kind of recurring constitutional issue the essay rewards.
