Answer:
The great migration was a mass movement of African Americans during the first, and second, world wars. After being enslaved, and trapped in sharecropping in the Jim Crow south, African Americans were in a dire state of being used and taken advantage of, even after slavery had successfully been abolished. During the first world war, however, most white men were off in Europe fighting within the final year of the first world war. African Americans saw this as an amazing advantage to be able to break free of sharecropping and move farther north where there would be a greater chance for switching from agriculture to industry and factories. So, to recap, African Americans migrated north to escape sharecropping, escape the Jim Crow laws of the south, and become more advantageous in the industries of the north.
