Rise of Fascism
Fascism is a political philosophy in which total power is given to a dictator and individual freedoms are denied.
Fascist dictators included Adolf Hitler (Germany), Benito Mussolini (Italy), and Hideki Tojo (Japan).
  These dictators led the countries that became known as the Axis Powers.

How did American policy toward events in Europe and Asia change over time?

As conflict grew in Europe and Asia, American foreign policy evolved from neutrality to direct involvement.

The Allies

USII.6c Impact of WWII

The student will demonstrate knowledge of the major causes and effects of American involvement in World War II by
c) describing the impact of World War II on the home front.

How did Americans at home support the war effort?

What effect did the war have on race relations in America?

World War II affected every aspect of American life.

Americans were asked to make sacrifices in support of the war effort and the ideas for which we fought.

American involvement in World War II brought an end to the Great Depression. Factories and workers were needed to produce goods to win the war.

Thousands of American women took jobs in defense plants during the war (e.g., Rosie the Riveter).

Americans at home supported the war by conserving and rationing resources.


Rosie the Riveter: Women in the Factories of World War II Women's work in factories during the war was essential. They were recruited with images of strong women like Rosie the Riveter

The need for workers temporarily broke down some racial barriers (e.g., hiring in defense plants) although discrimination against African Americans continued.

While many Japanese Americans served in the armed forces, others were treated with distrust and prejudice, and many were forced into internment camps.
