Between the period of 1910 to 1930, there was a migration movement called the Great Migration that made millions of African Americans move from the Southern States to the North and West, it is estimated that 6 million African Americans relocated during this period.
The main reason for the Great Migration was that the Southern States limited African Americans rights which made living very difficult, African Americans could not buy property, marry, vote and other things.
