Use this Discovering American History video entitled World War 1 1914 to 1920 to study the activist foreign policy of Progressive Presidents Roosevelt, Taft, and Wilson and how America became more interventionist in the Western Hemisphere, but when war broke out in Europe in 1914, most Americans did not see any national interest at stake. Learn how eventually the U.S. joined the Allies when Germany broke its pledges to restrict the use of the submarine. Discover how Americans mobilized rapidly, accepting unprecedented governmental control and how a drive to mobilize Americans' minds led to domestic hostility toward ethnic groups and "reds," and serious violations of civil rights that went largely unpunished. The war also affected women and African Americans.
