During the 1920s more than a million blacks moved from the South to cities in the North. What was not a result of that migration was "More blacks owned farms than at any earlier time in U.S. history."
We are talking about an important period in the United States modern history in which approximately 10 million African Americans decided to leave rural areas in the south to find better living conditions and work opportunities in the large cities of the north.
