Around 1910 until the late-1930s, there was a massive movement of African Americans (Blacks) that relocated from the "Deep South" (Southern United States) into Northern, Midwestern and Western U.S. industrial cities. Crop failure was one of the main reasons these Blacks left their traditional homes, some of it started by the Boll Weevil that had traveled from Mexico into Texas, then travel east into the Deep South. World Wars I and II also helped this migration. These welcoming and not-so-welcoming cities provided wartime jobs for these hordes.
