Answer:
To find wage-earning work
Step-by-step explanation:
Even though Civil War put an end on slavery, the government's inability to properly administrate the political and economic areas afterwards restricted African Americans' possibilities of being truly free. Actually, the end of the war resulted in a new system of racial control related to work.
For black people in the North, the ending of slavery meant that their loved ones in the South were less restricted, but in fact, they were not nearly free from the cruelty of the Peculiar Institution.
So, after the Civil War, African Americans from the South who used to be slaves moved to the cities located in the North and Midwest.
