What was the African American great migration in world war 1?

The Great Migration during World War I was a significant movement of African Americans from the rural South to urban areas in the North and West, primarily between 1916 and 1970. Driven by the search for better economic opportunities, escape from Jim Crow segregation, and the demand for labor in factories due to the war, millions relocated to cities like Chicago, Detroit, and New York. This migration not only transformed the Demographics of these urban centers but also had a profound impact on cultural expressions, laying the groundwork for the Harlem Renaissance and advancing the Civil Rights Movement.
