Questions 100 to 118: the 1900s to today

In this lesson · 6 sections

This is the longest stretch of history on the test. It's easier as a timeline, with one “why” for each war.

Wars and why the US joined

WarWhy the US entered
World War IGermany attacked U.S. ships
World War IIJapan attacked Pearl Harbor
Korean WarTo stop the spread of communism
Vietnam WarTo stop the spread of communism
Persian Gulf WarTo force the Iraqi military from Kuwait
After September 11, 2001War on Terror, Afghanistan, Iraq

Between the wars

  • 1920: women got the right to vote (19th Amendment).
  • 1929: the stock market crash started the Great Depression, the longest economic recession in modern history.
  • Franklin Roosevelt was president through the Depression and World War II.

The Cold War

The main rival was the Soviet Union. The main concerns were communism and nuclear war. Dwight Eisenhower, a World War II general, became the 34th president and created the Interstate highway system.

Civil rights

The civil rights movement fought to end racial discrimination. Martin Luther King, Jr. worked for equality, so that people would “not be judged by the color of their skin, but by the content of their character.”

September 11, 2001

Terrorists attacked the United States: two planes hit the World Trade Center in New York City, one the Pentagon, and one crashed in a field in Pennsylvania.

Two open-ended questions

For an American Indian tribe, pick one name you'll remember, such as Navajo or Cherokee. For an American innovation, the light bulb, the airplane or the moon landing all work.

Questions 113 and 115 are on the shorter list for the 65/20 special consideration.
