The great migration refers to

The Great Migration refers to the movement of millions of African Americans from the rural South to the urban areas of the North, Midwest, and West between the years of 1916 and 1970. This mass migration was motivated by a combination of push and pull factors. The push factors included economic disadvantages, racial violence, and the lack of social and political opportunities in the South. The pull factors included the promise of jobs, better living conditions, and greater freedom from racial discrimination in the North. The Great Migration had a profound impact on both the African American communities in the North and the South, leading to significant social, cultural, and political changes.
