War and American Neutrality

  • In 1914, Europe was ready for war.

    • Aggressive nationalisms divided nations and threatened multinational states like the Austro-Hungarian Empire.

    • Conflicts over Balkan spheres of influence and colonial possessions complicated relations between the great European powers.

  • Most dangerously, the most important European states formed two alliance systems.

    • In 1915, the Wilson administration allowed Wall Street banks to lend the Allies money to keep buying American goods.

      • Many Americans literally bet on an Allied victory.

    • In late 1914, the National Security League began an information campaign to convince Americans that war was necessary.

    • By 1915, Congress strengthened the army and navy.

    • Peace organizations arose nationwide to counter this, many were led by women.

  • German submarine warfare polarized Americans against the Central Powers.

    • The Germans could only attack British and French supply ships with U-boats because Allied warships dominated the sea.

    • U-boats warned ships before sinking them.

    • The Allies then equipped merchant ships with guns to sink unarmored submarines.

    • U-boats torpedoed ships without warning, killing crew and passengers.

    • Americans found this form of warfare barbaric and began calling Germans "Huns."

    • The Germans caved and signed the Sussex Pledge, promising not to sink ships without warning.

    • Wilson risked war if the Germans resumed full submarine warfare.


The Breakdown of German-American Relations

  • President Wilson appeared to have won peace.

    • He kept us out of war” was the Democratic slogan for his 1916 peace campaign.

    • Wilson narrowly defeated the reunited Republicans and their candidate, former New York governor and Supreme Court Justice Charles Evans Hughes, in the reelection.

  • Wilson's second inauguration led to war. European wars were bloody stalemates.

  • On January 31, 1917, Germany declared unrestricted submarine warfare to win.

    • They sank any Allies-supplied ship from then on. Neutral flags are useless.

    • Germans realized this would likely lead to war with the US.

    • They thought they could starve Britain and France before the Americans could help.

    • On February 3, Wilson cut ties with Germany. He requested Congress legalize merchant ship arming.

  • German foreign minister Arthur Zimmermann foolishly sent an inflammatory diplomatic note to Mexico as war loomed between Germany and the US.

    • In a German-American war, he encouraged the Mexicans to attack the US and promised German support for a Mexican reconquest of the American Southwest.

    • British intelligence intercepted and gave the Zimmermann Telegram to the Americans.

    • The Zimmermann Telegram enraged Americans and fueled war preparations.

  • Germans sank American ships bound for Britain and France as promised.

    • This violated the American belief that neutrals should sail wherever they wanted.

  • On April 2, President Wilson personally requested war against Germany from Congress.

    • Six senators and 50 representatives opposed the war, even though Congress overwhelmingly supported it.

    • Wilson tried to maintain American neutrality, but by the time the US entered the war, it was an Allies supply depot.


America in the War

  • In early 1917, the Allies were losing. Russia couldn't wage modern war.

    • In March 1917, the tsar was overthrown after many defeats and domestic chaos.

    • After the tsar's overthrow, the liberal government wanted to stay in the war and maintain relations with the western Allies.

    • This was doubted as Russian armies disintegrated.

    • The Germans might be able to move many troops from the Russian front to the western front.

    • Britain and France were exhausted. Disgusted French soldiers mutinied after a bloody offensive, denouncing callous leadership and demanding better treatment.

  • President Wilson sent troops to Europe.

    • General John J. Pershing was their leader.

    • Men between 17 and 46 could be drafted.

  • Pershing initially led few men to France due to the small American army.

    • The US military would need to expand greatly to fight a modern total war.

    • May brought the Selective Service Act.

      • Men between 17 and 46 could be drafted.

      • In segregated units with white officers, 400,000 African Americans served in the military.

      • 11,500 nurses and office workers wore uniform.

  • The army was unprepared, but the Navy was.

    • The Allies were suffering from German U-boats sinking ships in the Atlantic.

    • In May 1917, the US Navy led a convoy organization.

    • Navy-protected convoys were less vulnerable to submarine attack.

    • Better patrolling and convoys greatly reduced shipping losses.

    • The German submarines' strategic mission failed by war's end.


The American Expeditionary Force in France

  • By the end of the war, the American army had 4 million men, 2 million of whom were in France, thanks to volunteers and the draft.

  • In November 1917, the Bolshevik Revolution ended Russian war participation.

    • German troops flooded France.

    • By June 1918, they were 50 miles from Paris after a series of offensives.

  • Americans stopped the German advance on Paris at Chateau-Thierry.

    • September saw the AEF eliminate a German salient at St. Mihiel.

    • The American Meuse-Argonne Offensive began in late September and lasted until November.

      • This massive offensive involved a million American soldiers, cut a vital German supply line, and convinced the enemy they had lost the war.

  • On November 11, 1918, Germany declared an armistice.

    • The war killed 115,000 Americans, half of whom died in battle and the rest from disease, including the 1918 flu pandemic.

    • The 8 million European deaths dwarfed these losses.

    • Eddie Rickenbacker, the leading American flying ace, and Alvin York, who killed 25 German soldiers and captured 132 more in the Meuse-Argonne fighting, returned home heroes.


The Home Front

  • The government sought ways to engage Americans in the war.

    • Liberty Bonds could help civilians fund the war.

    • Celebrities like Charlie Chaplin promoted these bonds as a patriotic act.

  • In a massive regulatory expansion, the federal government took over most of the economy.

    • Food production and consumption were regulated by the 1917 Lever Food and Fuel Control Act.

    • The Food Administration was led by Herbert Hoover, famous for feeding European refugees.

      • Here, he increased food production and promoted "Wheatless Mondays" and "Meatless Tuesdays" to save food.

      • Farmers needed more time to harvest, so daylight saving time was introduced.

    • Fuel was conserved by a Fuel Administration.

      • It promoted "Fuelless Mondays" and "Gasless Sundays" to help Americans.

    • War production was supported by industrial resource allocation by the War Industries Board (WIB).

      • By the end of the war, the WIB was harnessing the nation's industrial might under Wall Street tycoon Bernard Baruch.

      • Railroads were under government control, allowing transportation priorities.

  • This unprecedented control of the economy has led some historians to view World War I as Progressivism's apex.

    • The government had powers that were unthinkable a few years earlier due to the wartime emergency.

    • Much of this was achieved with business and farm leaders' cooperation thanks to administrators like Baruch and Hoover.

  • The New Deal and World War II government agencies were modeled after World War I's economic mobilization.

    • But such an increase in government power also raised concerns about freedom.

    • Progressivism's triumph would provoke a backlash.


Regulating Thought

  • Regulation of public speech ultimately discredited government power.

  • In 1917, the government established the Committee on Public Information (CPI).

    • The CPI informed Americans about the war under journalist George Creel.

    • Explaining became propaganda. Lectures, books, posters, and films portrayed Germans as barbarians.

    • Newspapers were encouraged to censor anti-war stories by Creel.

    • Liberty Leagues were formed across the US to spy on neighbors and report any suspicious activity or disloyal talk to the authorities.

  • The war increased distrust of immigrants and "hyphenated Americans," especially German Americans.

  • Congress was convinced to test immigrants' literacy by the National Security League.

  • German music, food, and language were banned in some communities due to anti-German hysteria.

    • Individual German Americans were harassed or worse.

    • In April 1918, a German-American man who had joined the navy was mobbed and lynched in St. Louis.

  • Dissent was suppressed legally by the federal government. Interfering with the draft was illegal under the 1917 Espionage Act, and postal authorities could seize treasonous mail.

  • Criticizing the government, Constitution, or armed forces was illegal under the 1918 Sedition Act.

  • Thousands of Americans were charged with violating these laws, and over 1,000 were convicted.

    • For opposing the war, Eugene Debs was imprisoned.

    • Robert Goldstein, a film producer, was sentenced to three years in prison for making a film about the American Revolution in which the British were portrayed as villains.

    • Because the British were allies in the war, this previously unexceptionable view of the struggle for American independence was deemed sedition.

    • The government used these laws to break up radical organizations like the IWW.


Social Change

  • The war opened up economic possibilities for African Americans.

  • With millions of men entering the military and wartime demands on their capacity, northern industries needed workers.

  • African Americans living in the South moved north in the Great Migration.

  • During the war, 600,000 African Americans made this journey.

  • The war also made it possible for women to step into jobs that had not been open to them before the war.

  • Although most would leave these positions once the soldiers began returning home, their efforts during the war would help make the case for women’s suffrage.


Wilson and the Peace

  • Wilson wanted to lead the postwar international order.

    • He published his Fourteen Points, an idealistic program to build a peaceful world, while the war was still going on.

    • It included open diplomacy (no more secret military treaties), freedom of the seas, national self-determination, and a League of Nations.

    • Wilson attended the 1919 Paris Peace Conference, defying presidential precedent.

    • The "Big Four" allies—Britain, France, Italy, and the US—would lead peacemaking.

    • While ordinary Europeans hailed Wilson as a hero for his inspiring vision of a better future, the other allied leaders were less impressed and determined to press their national interests.

    • Wilson wanted a Fourteen Points peace, but the French wanted to punish Germany.

  • Wilson made many concessions during the tough Paris negotiations.

    • Germany had to apologize for starting the war and pay reparations to France and Britain.

    • Germany lost colonies, 10% of its territory, and most of its military.

    • German diplomats had to sign the Treaty of Versailles or be invaded.

    • German resentment over this treatment sparked World War II.

    • Wilson was disappointed by the Treaty of Versailles, but he thought the League of Nations would allow it to be fixed.

Americans and the Middle East

  • The United States had little interest in the Middle East until Theodore Roosevelt's diplomatic involvement in the 1905–1906 Moroccan crisis.

    • Great Power rivalries during and after World War I focused American attention on the region.

  • Turkey, or the Ottoman Empire, ruled much of the Middle East before the war.

  • For over a century, Turkey had been declining.

    • The empire's leaders hoped to stop this decline by joining the Central Powers. This was a big mistake.

    • The Ottoman Empire fell after defeat in the war.

    • Jews inspired by Zionism had been settling in Ottoman-ruled Palestine since the late nineteenth century.

  • The Balfour Declaration, which supported a Jewish state in Palestine, was issued by the British in 1917 to weaken the Turks.

    • A Jewish state was also supported by President Wilson.

    • Many American Jews gave Zionists money.

  • Turkish authorities became wary of the empire's Armenian minority as the war turned against them.

    • In 1915, the Christian Armenians were massacred and starved by the Turks.

    • American missionaries and diplomats spread the word of these atrocities.

    • The Armenian genocide was protested by thousands of Americans in 1916 and 1917.

  • The breakup of the Ottoman Empire was American policy under President Wilson.

    • He also wanted the German and Austro-Hungarian empires to fall.

    • He called for "autonomous political development" in all Central Power-ruled territories.

    • The US was authorized to form the King-Crane Commission to study Middle Eastern political aspirations at the Paris Peace Conference.

  • According to the King-Crane Commission, Middle Easterners wanted independence.

    • The British and French who defeated the Turks were deeply mistrusted.

  • The Middle Eastern people preferred the Americans to control territory if any of the Allies were given a mandate.

    • They believed the Americans had no long-term interests in the region.

  • Britain and France's imperial ambitions were challenged by the King-Crane Commission.

    • These Allies buried the commission's report.

    • The British and French split most of the Middle East.

    • The British received mandates in Palestine, Transjordan, and Iraq, and the French in Lebanon and Syria.

    • Saudi Arabia alone was independent by the early 1920s.


Woodrow Wilson’s Defeat

  • The Constitution requires a two-thirds Senate vote to ratify all treaties.

    • Wilson did not include a senator in his Paris delegation.

    • Despite Republicans controlling both houses of Congress in 1918, he failed to bring a prominent Republican politician.

    • Wilson returned to the US to find Republicans opposed to the Treaty of Versailles.

  • Most Republican and some Democratic senators worried that the League's collective security provisions would draw the US into more wars.

    • Twelve senators were "irreconcilables" and refused to vote for the treaty and League.

  • Most Republicans followed Senate Foreign Relations Committee chairman Henry Cabot Lodge.

    • Lodge wanted the American ratification of the treaty to include League reservations.

    • This made his supporters "reservationists."

    • Lodge wanted to ensure that the League of Nations would not invalidate the Monroe Doctrine and that Congress would authorize American military actions on behalf of the League.

  • Important European leaders stated that they preferred the treaty's passage with reservations to its Senate failure. Wilson refused to compromise.

    • The president was too committed to the League to give in to his critics. Wilson's health was declining.

  • In September 1919, he embarked on a grueling speaking tour to persuade Americans about the League.

    • A stroke disabled Wilson on October 2.

    • The president recovered partially, but the stroke made him less willing to compromise, including on the League.

  • Wilson ordered loyal Democratic senators to vote against the League with reservations.

    • In 1919 and 1920, the Senate rejected the Treaty of Versailles and the League of Nations due to the reservationists' and irreconcilables' strong positions.

    • America never joined the League of Nations.

    • This severely weakened the League, which failed to prevent World War II.

    • The United States would remain active in world affairs in the 1920s after rejecting the League.

  • In 1921, Wilson left office physically broken.

    • His successor, Warren G. Harding, signed separate peace treaties with the former Central Powers that year to end America's involvement in World War I.

    • Food production and consumption were regulated by the 1917 Lever Food and Fuel Control Act.

    • The Food Administration was led by Herbert Hoover, famous for feeding European refugees.

      • Here, he increased food production and promoted "Wheatless Mondays" and "Meatless Tuesdays" to save food.

      • Farmers needed more time to harvest, so daylight saving time was introduced.

    • Fuel was conserved by a Fuel Administration.

      • It promoted "Fuelless Mondays" and "Gasless Sundays" to help Americans.

    • War production was supported by industrial resource allocation by the War Industries Board (WIB).

      • By the end of the war, the WIB was harnessing the nation's industrial might under Wall Street tycoon Bernard Baruch.

      • Railroads were under government control, allowing transportation priorities.

  • This unprecedented control of the economy has led some historians to view World War I as Progressivism's apex.

    • The government had powers that were unthinkable a few years earlier due to the wartime emergency.

    • Much of this was achieved with business and farm leaders' cooperation thanks to administrators like Baruch and Hoover.

  • The New Deal and World War II government agencies were modeled after World War I's economic mobilization.

    • But such an increase in government power also raised concerns about freedom.

    • Progressivism's triumph would provoke a backlash.


Regulating Thought

  • Regulation of public speech ultimately discredited government power.

  • In 1917, the government established the Committee on Public Information (CPI).

    • The CPI informed Americans about the war under journalist George Creel.

    • Explaining became propaganda. Lectures, books, posters, and films portrayed Germans as barbarians.

    • Newspapers were encouraged to censor anti-war stories by Creel.

    • Liberty Leagues were formed across the US to spy on neighbors and report any suspicious activity or disloyal talk to the authorities.

  • The war increased distrust of immigrants and "hyphenated Americans," especially German Americans.

  • Congress was convinced to test immigrants' literacy by the National Security League.

  • German music, food, and language were banned in some communities due to anti-German hysteria.

    • Individual German Americans were harassed or worse.

    • In April 1918, a German-American man who had joined the navy was mobbed and lynched in St. Louis.

  • Dissent was suppressed legally by the federal government. Interfering with the draft was illegal under the 1917 Espionage Act, and postal authorities could seize treasonous mail.

  • Criticizing the government, Constitution, or armed forces was illegal under the 1918 Sedition Act.

  • Thousands of Americans were charged with violating these laws, and over 1,000 were convicted.

    • For opposing the war, Eugene Debs was imprisoned.

    • Robert Goldstein, a film producer, was sentenced to three years in prison for making a film about the American Revolution in which the British were portrayed as villains.

    • Because the British were allies in the war, this previously unexceptionable view of the struggle for American independence was deemed sedition.

    • The government used these laws to break up radical organizations like the IWW.


Social Change

  • The war opened up economic possibilities for African Americans.

  • With millions of men entering the military and wartime demands on their capacity, northern industries needed workers.

  • African Americans living in the South moved north in the Great Migration.

  • During the war, 600,000 African Americans made this journey.

  • The war also made it possible for women to step into jobs that had not been open to them before the war.

  • Although most would leave these positions once the soldiers began returning home, their efforts during the war would help make the case for women’s suffrage.


Wilson and the Peace

  • Wilson wanted to lead the postwar international order.

    • He published his Fourteen Points, an idealistic program to build a peaceful world, while the war was still going on.

    • It included open diplomacy (no more secret military treaties), freedom of the seas, national self-determination, and a League of Nations.

    • Wilson attended the 1919 Paris Peace Conference, defying presidential precedent.

    • The "Big Four" allies—Britain, France, Italy, and the US—would lead peacemaking.

    • While ordinary Europeans hailed Wilson as a hero for his inspiring vision of a better future, the other allied leaders were less impressed and determined to press their national interests.

    • Wilson wanted a Fourteen Points peace, but the French wanted to punish Germany.

  • Wilson made many concessions during the tough Paris negotiations.

    • Germany had to apologize for starting the war and pay reparations to France and Britain.

    • Germany lost colonies, 10% of its territory, and most of its military.

    • German diplomats had to sign the Treaty of Versailles or be invaded.

    • German resentment over this treatment sparked World War II.

    • Wilson was disappointed by the Treaty of Versailles, but he thought the League of Nations would allow it to be fixed.

Americans and the Middle East

  • The United States had little interest in the Middle East until Theodore Roosevelt's diplomatic involvement in the 1905–1906 Moroccan crisis.

    • Great Power rivalries during and after World War I focused American attention on the region.

  • Turkey, or the Ottoman Empire, ruled much of the Middle East before the war.

  • For over a century, Turkey had been declining.

    • The empire's leaders hoped to stop this decline by joining the Central Powers. This was a big mistake.

    • The Ottoman Empire fell after defeat in the war.

    • Jews inspired by Zionism had been settling in Ottoman-ruled Palestine since the late nineteenth century.

  • The Balfour Declaration, which supported a Jewish state in Palestine, was issued by the British in 1917 to weaken the Turks.

    • A Jewish state was also supported by President Wilson.

    • Many American Jews gave Zionists money.

  • Turkish authorities became wary of the empire's Armenian minority as the war turned against them.

    • In 1915, the Christian Armenians were massacred and starved by the Turks.

    • American missionaries and diplomats spread the word of these atrocities.

    • The Armenian genocide was protested by thousands of Americans in 1916 and 1917.

  • The breakup of the Ottoman Empire was American policy under President Wilson.

    • He also wanted the German and Austro-Hungarian empires to fall.

    • He called for "autonomous political development" in all Central Power-ruled territories.

    • The US was authorized to form the King-Crane Commission to study Middle Eastern political aspirations at the Paris Peace Conference.

  • According to the King-Crane Commission, Middle Easterners wanted independence.

    • The British and French who defeated the Turks were deeply mistrusted.

  • The Middle Eastern people preferred the Americans to control territory if any of the Allies were given a mandate.

    • They believed the Americans had no long-term interests in the region.

  • Britain and France's imperial ambitions were challenged by the King-Crane Commission.

    • These Allies buried the commission's report.

    • The British and French split most of the Middle East.

    • The British received mandates in Palestine, Transjordan, and Iraq, and the French in Lebanon and Syria.

    • Saudi Arabia alone was independent by the early 1920s.


Woodrow Wilson’s Defeat

  • The Constitution requires a two-thirds Senate vote to ratify all treaties.

    • Wilson did not include a senator in his Paris delegation.

    • Despite Republicans controlling both houses of Congress in 1918, he failed to bring a prominent Republican politician.

    • Wilson returned to the US to find Republicans opposed to the Treaty of Versailles.

  • Most Republican and some Democratic senators worried that the League's collective security provisions would draw the US into more wars.

    • Twelve senators were "irreconcilables" and refused to vote for the treaty and League.

  • Most Republicans followed Senate Foreign Relations Committee chairman Henry Cabot Lodge.

    • Lodge wanted the American ratification of the treaty to include League reservations.

    • This made his supporters "reservationists."

    • Lodge wanted to ensure that the League of Nations would not invalidate the Monroe Doctrine and that Congress would authorize American military actions on behalf of the League.

  • Important European leaders stated that they preferred the treaty's passage with reservations to its Senate failure. Wilson refused to compromise.

    • The president was too committed to the League to give in to his critics. Wilson's health was declining.

  • In September 1919, he embarked on a grueling speaking tour to persuade Americans about the League.

    • A stroke disabled Wilson on October 2.

    • The president recovered partially, but the stroke made him less willing to compromise, including on the League.

  • Wilson ordered loyal Democratic senators to vote against the League with reservations.

    • In 1919 and 1920, the Senate rejected the Treaty of Versailles and the League of Nations due to the reservationists' and irreconcilables' strong positions.

    • America never joined the League of Nations.

    • This severely weakened the League, which failed to prevent World War II.

    • The United States would remain active in world affairs in the 1920s after rejecting the League.

  • In 1921, Wilson left office physically broken.

    • His successor, Warren G. Harding, signed separate peace treaties with the former Central Powers that year to end America's involvement in World War I.
