Answer:
The 1920s saw many social and cultural changes in the U.S. Prohibition led to increased organized crime and speakeasies where people gathered illegally to drink alcohol. Population shifts occurred as many African Americans migrated from the rural South to cities like Harlem, ushering in the Harlem Renaissance of black arts, literature, and music. Women gained the right to vote, and dresses and hairstyles became more daring, reflecting women's movements for more freedom and independence. The Jazz Age saw the rise of jazz music and dance halls and a more liberated attitude toward sex and morality. Meanwhile, the Harlem Renaissance produced great African American writers, artists, and thinkers who celebrated and shaped black culture, redefining what it meant to be an American. Together, these trends transformed American society in lasting ways.
