American Entry to WWI
Unit Objective:
To assess the reasons for American entry to and involvement in WWI

2. America did not enter the war until 1917—why not sooner?
1.) President Woodrow Wilson wanted America to be a model of peace and going to war was not considered “Progressive”, so Wilson tried to keep America out of the war; Wilson was re-elected in part due to the campaign slogan “He kept us out of war”

3. 2.) Most Americans thought the war had nothing to do with America and America had not been included in any European alliances because the world powers still did not consider America their equal; Many Americans wanted to follow George Washington’s advice from his Farewell Address—stay out of foreign conflicts

4. 3.) Many Americans were of German or Irish descent—What did that matter?

5. German-Americans:
Irish-Americans:

6. Why did America finally decide to enter the war?
America was naturally drawn to the British side
because we shared a common culture,
background, and ethnicity
The British had cut the Transcontinental cable
that America relied on for information about
what was going on in Europe making
America dependent on Britain for that
information

11. A U-Boat and the Lusitania

12. Sussex Pledge:
Germans promised to stop sinking merchant
ships without warning—Germany was not yet
ready for America to enter the war (would
have strengthened the Allies) and the agreement
allowed Wilson to keep America out of the war a
little longer (helped get him re-elected in 1916)
