The Jazz Age, also known as the Roaring Twenties, was a period of cultural and social change in the 1920s in which jazz music and dance styles gained worldwide popularity. The Jazz Age was intertwined with the developing youth culture and helped introduce the European jazz movement. The decade was characterized by prosperity, dissipation, and jazz bands, bootleggers, raccoon coats, bathtub gin, flappers, flagpole sitters, bootleggers, and marathon dancers. However, the economic boom and the Jazz Age came to an end, and America began the period called the Great Depression. Jazz continued to evolve and develop into new styles such as swing, bebop, cool jazz, and hard bop. Therefore, what came after the Jazz Age was a period of economic depression and the evolution of jazz music into new styles.
