  • Emergency Immigration Act

    The Emergency Immigration Act was used as a temporary buffer for law makers to create the National Origins Act in 1924. These acts established an immigration quota based on immigrants' country of origin. The act only allowed 2% of the number of immigrants from the same country living in America in 1890. The acts also completely excluded Asian immigrants.
  • John T. Scopes

    John T. Scopes was placed on trial for violating the Butler Act, which prohibited the teaching of anti-Biblical theories (such as Darwin's evolution theory) to students. The case was later thrown-out on a technicality, but the conflict between these two spheres continued.
  • Roosevelt Promises a New Deal

    In his acceptance speech for the Democratic Presidential nomination, Franklin D. Roosevelt promised a 'new deal' for Americans. Originally it was a figure of speech, but New Deal became the overarching name for the many programs which Roosevelt made to help end the Great Depression. This campaign promise helped Roosevelt win the election against Hoover.

  • Black Tuesday

    The stock market crash led to credit vanishing, which in turn led to a run on the banks. Ultimately, Black Tuesday is seen as the beginning step toward the Great Depression.
  • Manchuria Railroad Explosion

    In 1931, part of the railroad exploded in what the Japanese claimed was an attack by anti-Japanese dissidents. It was later determined that the explosion was actually planned by the Japanese. The Japanese used the explosion as an excuse to invade China and take control of the Manchuria province. This incident began the Asian section of World War II.
  • Pearl Harbor Attack

    Japan launched a surprise attack on the American Naval forces at Pearl Harbor in Hawaii. The Japanese saw American intervention in the war inevitable, so they hoped a sudden attack would cripple the navy. The attack succeeded in taking thousands of American lives and destroying several vessels. However, Pearl Harbor pushed America toward cooperation with the Allies in Europe and ultimately caused the United States to join World War II.
