The Great Migration significantly altered the demographics of America in the 20th century, as millions of African Americans relocated from the rural South to urban areas in the North and West. This mass movement, driven by factors such as economic opportunity, racism, and the quest for better living conditions, resulted in increased diversity in major cities. It also led to profound cultural changes, giving rise to the Harlem Renaissance and influencing political landscapes. By reshaping the urban experience, the Great Migration played a vital role in establishing a more integrated society, despite ongoing challenges related to discrimination.
