This migration was one of the single most largest and rapid mass movements in American history. close to 50% of the African American population in the south moved North or West within a 10 year span, experts feel the Migration was fueled by the immediate threat of Execution and other danger in the South. One of the biggest influencers that attracted blacks to Chicago was Robert S. Abbott, he founded a newspaper called The Chicago Defender which was primarily published for African Americans. The newspaper campaigned against Jim Crow laws and urged blacks in the South to come North. Chicago was viewed to Southern blacks as the promise land because of the stories they heard about big city life with well paying jobs, good living conditions, and basic freedoms they did not receive in the south.
Once in Chicago Blacks mostly moved to the West and South Side of the city were they had their own neighborhoods but were nearly neglected. As Chicago grew so did the African American Influence. The construction of the Dan Ryan Displaced many blacks around the city to neighborhoods such as englewood, West Garfield Park, and Auburn Gresham. These neighborhoods remain mostly black communities and due to the lack of city funding, lack of income, and violence these neighborhoods are some of the worse in the city.
