The widespread prosperity of the 1920s ended abruptly with the stock market crash in October 1929 and the Great Depression that followed. Threatening jobs, savings, homes, and farms, at its height, about one-fourth of the American workforce was out of work. To help, President Franklin Roosevelt instituted the “New Deal,” a series of programs, public work projects, financial reforms, and regulations. Worldwide economic problems and instability led to dictatorial regimes and eventually World War II.
After the war, many Americans became more affluent. Some were not so lucky, such as African Americans, Hispanics, and women, who became more aggressive in winning their full freedoms. In the next decades, tension emerged with the Cold War, Communist fears, and other foreign military matters, including Korea, Vietnam, and the Middle East.
