c) The Great Migration
The Great Migration, starting around 1916, was a major event in American history that saw the movement of over 6 million African Americans from the rural South to urban areas in the North and West. Driven by the desire to escape racial segregation, violence, and limited economic opportunities in the South, African Americans sought better lives in Northern and Western cities. This migration significantly transformed the demographic, cultural, and political landscape of urban America. It contributed to the development of vibrant African American communities and had a profound impact on American culture, particularly in the realms of music, art, and literature.
