How did the US respond to the breakout of war in Europe?

The US responded to the start of a war in Europe by declaring its neutrality.

What did the US really mean by “neutral?”

What prevented the US from remaining neutral? What caused the US to enter the war in 1917?

With your partner, generate a list of reasons the US entered the “Great War” in 1917.

The “preparedness” movement

• Business leaders who had strong commercial ties to Great Britain urged the US to get ready for war.

• Their “watchword” was preparedness.

President Wilson asked Congress for funds to build up the armed forces & established a council of National Defense to increase cooperation between the military and private industry.

“The Peace” Movement

Consisted of Progressives, Socialists, and Populists. Women were particularly active. On August 29, 1914, suffragists, dressed in black and carrying a banner of a dove, marched down New York City’s Fifth Avenue. Jeannette Rankin, the first female elected to Congress, voted against US involvement in the war. Jane Addams was another supporter of neutrality.

They argued that if the US was going to “prepare” for war,” Congress should tax the makers of arms and increase income taxes to pay for the increase in the army and navy. This would be unpopular with the American people, resulting in the US staying neutral.

However, Congress still increased taxes!

“The World must be made safe for democracy.” (Woodrow Wilson)

Discuss with your Partner:What do you think President Wilson meant by this statement? Was it a valid reason for US involvement in WWI? Why or why not?

MOBILIZATION

• For an entire year after the US entry into the war (1917), its main contributions to the Allies were large supplies of food, guns, ships, airplanes, & other goods.

• FACTORIES – Bernard Baruch headed the War Industries Board – convert products & methods to wartime needs

• FOOD SUPPLY – Herbert Hoover, Food Administrator – voluntary action – “meatless Mondays, wheatless Wednesdays, “Gospel of the Clean Plate”

Mobilization continued

Women & Minorities began to take the place of men who entered the armed forces.“Great Migration” – African Americans had begun to move North prior to the war, but large numbers of African Americans migrated North during the war to find jobs.
