Through World War I, Interwar period and Great Depression

The United States tried and failed to broker a peace settlement for World War I, then entered the war after Germany launched a submarine campaign against U.S. merchant ships that were supplying Germany's enemy countries. The publicly stated goals were to uphold American honor, crush German militarism, and reshape the postwar world. After a slow mobilization, the United States of America helped bring about a decisive victory by supplying badly needed financing, food, and millions of fresh and eager soldiers. After the war, the United States of America rejected the Treaty of Versailles and did not join the League of Nations.

In 1920, the manufacture, sale, import and export of alcohol was prohibited by the Eighteenth Amendment to the United States Constitution. Possession of liquor, and drinking it, was never illegal before. The overall level of alcohol consumption did go down, however, state and local governments avoided aggressive enforcement. The federal government was overwhelmed with cases, so that bootlegging and speakeasies flourished in every city. Well-organized criminal gangs exploded in numbers, finances, power, and influence on city politics.

A few local domestic-terrorist attacks from radicals, like the 1920 Wall Street Bombing and the 1919 United States anarchist bombings sparked the first Red Scare. Culture wars between fundamentalist Christians and modernists became more intense, as demonstrated by prohibition, the Ku Klux Klan (KKK), and the highly publicized Scopes Trial.

The nation enjoyed a period of sustained prosperity in the 1920s. Agriculture went through a bubble in soaring land prices that collapsed in 1921, and that sector remained depressed. Coal mining was shrinking as oil became the main energy source. Otherwise most sectors prospered. Construction flourished as office buildings, factories, paved roads, and new housing was evident everywhere. Automobile production soared, suburban housing expanded and the nation's homes, towns and cities were electrified, along with some farms. Prices were stable, and the Gross Domestic Product (GDP) grew steadily until 1929, when the financial speculation bubble burst as Wall Street crashed.

In foreign policy President Wilson helped found the League of Nations but the U.S. never joined it, as the Congress refused to give up its constitutional role in declaring war. The nation instead took the initiative to disarm the world, most notably at the Washington Conference in 1921–22. Washington also helped stabilize the European economy through the Dawes Plan and the Young Plan. The Immigration Act of 1924 was aimed at stabilizing the traditional ethnic balance and strictly limiting the total inflow. The act completely blocked Asian immigrants, providing no means for them to get in.

The Wall Street Crash of 1929 and the ensuing Great Depression led to government efforts to restart the economy and help its victims. The recovery, however, was very slow. The nadir of the Great Depression was 1933, and recovery was rapid until the recession of 1938 proved a setback. There were no major new industries in the 1930s that were big enough to drive growth the way autos, electricity and construction had been so powerful in the 1920s. GDP surpassed 1929 levels in 1940.

By 1939, isolationist sentiment in America had ebbed, and after the stunning fall of France in 1940 to Nazi Germany, the United States began rearming itself and sent a large stream of money and military supplies to Britain and the Soviet Union. Following the attack on Pearl Harbor, the United States entered World War II to fight against Nazi Germany, Fascist Italy, and Imperial Japan, known as the "Axis powers". Italy surrendered in 1943, and Germany and Japan in 1945, after massive devastation and loss of life, while the US emerged far richer and with few casualties.

World War I

Entry

Firmly maintaining neutrality when World War I began in Europe in 1914, the United States helped supply the Allies, but could not ship anything to the Central Powers because of the British blockade of Germany. Sympathies among many politically and culturally influential Americans had favored the British cause from the start of the war, as typified by industrialist Samuel Insull, born in London, who helped young Americans enlist in British or Canadian forces. On the other hand, especially in the Midwest, many Irish Americans and German Americans opposed any American involvement, the Irish because they hated the British, and the Germans because they feared they would come under personal attack. The suffragist movement included many pacifists, and most churches opposed the war.

German efforts to use their submarines ("U-boats") to blockade Britain resulted in the deaths of American travelers and sailors, and attacks on passenger liners caused public outrage. Most notable was torpedoing without warning the passenger liner Lusitania in 1915. Germany promised not to repeat; however it reversed position in early 1917, believing that unrestricted U-boat warfare against all ships headed to Britain would win the war, albeit at the cost of American entry. When Americans read the text of the German offer to Mexico, known as the Zimmermann Telegram, they saw an offer for Mexico to go to war with Germany against the United States, with German funding, with the promise of the return of the lost territories of Arizona, New Mexico, and Texas. On April 1, 1917, Wilson called for war, emphasizing that the U.S. had to fight to maintain its honor and to have a decisive voice in shaping the new postwar world. Congress voted on April 6, 1917, to declare war, but it was far from unanimous.

Germany

German Americans were sometimes accused of being too sympathetic to the German Empire. Former president Theodore Roosevelt denounced "hyphenated Americanism", insisting that dual loyalties were impossible in wartime. A small minority came out for Germany, or ridiculed the British. About 1% of the 480,000 enemy aliens of German birth were imprisoned in 1917–18. The allegations included spying for Germany, or endorsing the German war effort. Thousands were forced to buy war bonds to show their loyalty. One person was killed by a mob; in Collinsville, Illinois, German-born Robert Prager was dragged from jail as a suspected spy and lynched. The war saw a phobia of anything German engulf the nation; sauerkraut was rechristened "liberty cabbage".

Patriotism

The Wilson Administration created the Committee on Public Information (CPI) to control war information and provide pro-war propaganda. The private American Protective League, working with the Federal Bureau of Investigation, was one of many private right-wing "patriotic associations" that sprang up to support the war and at the same time fight labor unions and various left-wing and anti-war organizations. The U.S. Congress passed, and Wilson signed, the Espionage Act of 1917 and the Sedition Act of 1918. The Sedition Act criminalized any expression of opinion that used "disloyal, profane, scurrilous or abusive language" about the U.S. government, flag or armed forces. Government police action, private vigilante groups and public war hysteria compromised the civil liberties of many Americans who disagreed with Wilson's policies.

Draft

The United States was remarkably unprepared for war in 1917, since it had not fought a major conflict since 1865. The military was small by modern standards and used out-dated weapons. A hasty expansion and modernization of the armed forces was thus launched. The draft began in spring 1917 but volunteers were also accepted. Four million men and thousands of women joined the services for the duration.

Economic confusion in 1917

In terms of munitions production, the 15 months after April 1917 involved an amazing parade of mistakes, misguided enthusiasm, and confusion. Americans were willing enough, but they did not know their proper role. Washington was unable to figure out what to do when, or even to decide who was in charge. Typical of the confusion was the coal shortage that hit in December 1917. Because coal was by far the major source of energy and heat a grave crisis ensued. There was in fact plenty of coal being mined, but 44,000 loaded freight and coal cars were tied up in horrendous traffic jams in the rail yards of the East Coast. Two hundred ships were waiting in New York Harbor for cargo that was delayed by the mess. The solution included nationalizing the coal mines and the railroads for the duration, shutting down factories one day a week to save fuel, and enforcing a strict system of priorities. Only in March 1918 did Washington finally take control of the crisis.

Women

The war saw many women taking what were traditionally men's jobs for the first time. Many worked on the assembly lines of factories, producing tanks, trucks and munitions. For the first time, department stores employed African American women as elevator operators and cafeteria waitresses. The Food Administration helped housewives prepare nutritious meals with less waste and with optimum use of the foods available. Most important, the morale of the women remained high, as millions joined the Red Cross as volunteers to help soldiers and their families. With rare exceptions, the women did not protest the draft.

Labor

Samuel Gompers, head of the American Federation of Labor, and nearly all labor unions were strong supporters of the war effort. They minimized strikes as wages soared and full employment was reached. The AFL unions strongly encouraged their young men to enlist in the military, and fiercely opposed efforts to reduce recruiting and slow war production by the anti-war labor union called the Industrial Workers of the World (IWW) and also left-wing Socialists. President Wilson appointed Gompers to the powerful Council of National Defense, where he set up the War Committee on Labor. The AFL membership soared to 2.4 million in 1917. In 1919, the Union tried to make their gains permanent and called a series of major strikes in meat, steel and other industries. The strikes, all of which failed, forced unions back to their position around 1910. Anti-war socialists controlled the IWW, which fought against the war effort and was in turn shut down by legal action by the federal government.

American Expeditionary Forces

On the battlefields of the Western Front, the fresh American Expeditionary Forces troops were enthusiastically welcomed by the war-weary Allied armies in the summer of 1918. They arrived at the rate of 10,000 a day, at a time that the Imperial German Army was unable to replace its losses. After the Allies turned back the powerful final German offensive (Spring Offensive), the Americans played a central role in the Allied final offensive (Hundred Days Offensive). Victory over Germany was achieved on November 11, 1918.

Using questionnaires filled out by doughboys as they left the Army, Gutièrrez reported they were not cynical or disillusioned. They fought "for honor, manhood, comrades, and adventure, but especially for duty."

Aftermath

A popular Tin Pan Alley song of 1919 asked, concerning the United States troops returning from World War I, "How Ya Gonna Keep 'em Down on the Farm (After They've Seen Paree)?". In fact, many did not remain "down on the farm"; there was a great migration of youth from farms to nearby towns and smaller cities. The average distance moved was only 10 miles (16 km). Few went to the cities with over 100,000 people. However, agriculture became increasingly mechanized with widespread use of the tractor, other heavy equipment, and superior techniques disseminated through County Agents, who were employed by state agricultural colleges and funded by the Federal government.

In 1919, Woodrow Wilson campaigned for congress to ratify the Treaty of Versailles and allow the U.S. to join the new League of Nations, which he had been instrumental in creating. Wilson rejected the Republican compromise on the issue, and it failed for lack of a 2/3 majority. During his grueling cross-country tour to promote the League, Wilson suffered a series of strokes. He never recovered physically and lost his leadership skills and was unable to negotiate or compromise. The Senate rejected entry into the League and the U.S. never joined.

Defeat in the Great War left Germany in a state of revolutionary turmoil and heavily in debt for war reparations, payments to the victorious Allies. The Allies in turn owed large sums to the US Treasury for war loans. Under the multi-national Dawes Plan, American and British banks loaned money to Germany to stabilize its currency and expand production, which then allowed it to pay reparations to countries like Britain and France. In the 1920s, European and American economies reached new levels of industrial production and prosperity.
