Why is the 1920s known as the jazz age?

The 1920s is known as the Jazz Age due to the explosive popularity of Jazz Music and culture during this decade. This era marked a significant cultural shift, with jazz becoming a symbol of the social and artistic liberation of the time, particularly among African American communities. Speakeasies, dance halls, and radio broadcasts helped popularize jazz, contributing to a vibrant nightlife and a new sense of freedom and modernity. The Jazz Age also reflected broader changes in society, including the emergence of the "flapper" culture and shifts in social norms.
