The year that marked the beginning of the Roaring Twenties in the United States is 1920. Following the end of World War I, this decade became synonymous with economic prosperity, cultural dynamism, and significant social change. The 1920s saw the rise of jazz music, flapper culture, and the Harlem Renaissance, which celebrated African American heritage. The introduction of consumer goods, coupled with a surge in automobiles and the expansion of radio, transformed American life. However, this vibrant era also led to increased societal divides and culminated in the stock market crash of 1929, which heralded the onset of the Great Depression.
