What made the 1920s decade so different from the one before it and the after it?

The 1920s, often referred to as the "Roaring Twenties," was marked by significant social, cultural, and economic changes that distinguished it from the preceding and following decades. Following World War I, the decade experienced a surge in consumerism, technological advancements, and the rise of jazz and flapper culture, reflecting a break from traditional norms. In contrast, the 1930s were characterized by the Great Depression, leading to economic hardship and a return to more conservative values. This vibrant and transformative era set the stage for modern American society, emphasizing individualism and a shift in social dynamics.
