Why do historians consider 1920s a period of contradictions?

Historians consider the 1920s a period of contradictions due to the stark contrasts between social progress and conservative backlash. On one hand, this decade saw significant cultural advancements, including the Jazz Age, women's suffrage, and the Harlem Renaissance, which celebrated diversity and modernity. Conversely, it was also marked by the rise of nativism, Prohibition, and widespread social conservatism, reflecting a resistance to these changes. This duality underscores the tension between modernity and tradition that characterized the era.
