This document provides a summary of the Great Migration that occurred between 1900-1970, when around 6 million African Americans left the rural South and moved to major cities in the North like Chicago, New York, Detroit, and Cleveland. It was sparked by the desire to escape racism and Jim Crow laws and seek better jobs and opportunities. The Chicago Defender newspaper encouraged this migration by portraying the North as a "Promised Land." Many talented artists and writers also moved North during this time and contributed to the Harlem Renaissance. The migration slowed during the Depression but increased again during World War II due to more factory jobs.
