Currently reading and learning a lot:
It's about the migration from the south to north and west by African Americans starting around WWI and continuing until the late 1960s once Civil Rights legislation was passed.

Unfortunately the prejudices and segregation continued but not to the same deadly degree. For one thing there was the right to vote and better paying work.
