24 World War 2

Leading up to World War II

The devastation of the Great War (as World War I was known at the time) had greatly destabilized Europe, and in many respects World War II grew out of issues left unresolved by that earlier conflict. In particular, political and economic instability in Germany, and lingering resentment over the harsh terms imposed by the Versailles Treaty, fueled the rise to power of Adolf Hitler and National Socialist German Workers’ Party, abbreviated as NSDAP in German and the Nazi Party in English.

Outbreak of World War II (1939)

In late August 1939, Hitler and Soviet leader Joseph Stalin signed the German-Soviet Nonaggression Pact, which incited a frenzy of worry in London and Paris. Hitler had long planned an invasion of Poland, a nation to which Great Britain and France had guaranteed military support if it were attacked by Germany. The pact with Stalin meant that Hitler would not face a war on two fronts once he invaded Poland, and would have Soviet assistance in conquering and dividing the nation itself. On September 1, 1939, Hitler invaded Poland from the west; two days later, France and Britain declared war on Germany, beginning World War II.

4) Japan and China were already at war in 1937

People often describe World War II as beginning in September 1939 when Germany invaded Poland. But Japan and China had already been at war for several years at that point. China was politically chaotic in the early 1930s, and Japan saw opportunities for territorial expansion. Japan established a puppet state called Manchukuo in Manchuria in 1932 and dispatched troops to the area. Tensions escalated into full-scale war by 1937. This map shows the situation in 1940; the areas in pink were under Japanese control. Japan never gained full control of China, but neither could Chinese forces under Chiang Kai-shek expel the Japanese from Chinese territory without help from the United States.

Consequences:

  1. 1. The war ended Depression unemployment and dramatically expanded government’s presence in American life. It led the federal government to create a War Production Board to oversee conversion to a wartime economy and the Office of Price Administration to set prices on many items and to supervise a rationing system.
  2. 2. During the war, African Americans, women, and Mexican Americans founded new opportunities in industry. But Japanese Americans living on the Pacific coast were relocated from their homes and placed in internment camps.
