The end of World War I led America into a decade of wealth, prosperity, and social change known as the “Roaring Twenties.” Mass production and new technologies led to an increase in consumer goods, urbanization, new forms of transportation and entertainment. However, fears of rapid social and cultural changes, especially changes in American cities, led to an anti-socialist “Red Scare,” a rise in nativism and new immigration restrictions, and a commitment to religious fundamentalism. The roaring twenties came to a screeching halt in October 1929 as a result of a stock market crash, overproduction, and unequal distribution of wealth. The U.S. plunged into the Great Depression. When Franklin Roosevelt became president in 1932, he began a series of reforms known as the New Deal, which attempted to resolve issues that had led to the Depression, as well as provide new jobs for unemployed Americans. Many of the institutions established by the New Deal still exist today.
