Great Migration (African American)

The Great Migration, sometimes known as the Great Northward Migration or the Black Migration, was the movement of six million Black Americans out of the rural Southern United States to the urban Northeast, Midwest, and West between 1910 and 1970. It was substantially caused by poor economic and social conditions due to prevalent racial segregation and discrimination in the Southern states where Jim Crow laws were upheld.
