The Global Context of World War II

Major Causes

• Fascism arose from the economic turmoil of the Great Depression, leading authoritarian regimes in Germany, Italy, and Japan.

• The Treaty of Versailles post-WWI created resentment in Germany, leading to nationalism and militarism.

• Isolationist sentiment in the U.S. complicated early interventionist policies.

Major Events Leading to U.S. Involvement

• Pearl Harbor (December 7, 1941): Catalyst for U.S. entry into the war.

• Initial isolationism transformed into advocacy for intervention by figures like FDR and Winston Churchill.

• US involvement linked to defense of democracy against fascism.

The War's Dynamics

Military Mobilization and Organization

• The U.S. military mobilized over 16 million citizens, employing a diverse demographic including women and minorities.
