What factors lead to the end of many black towns

  Events of the 1920s and 1930s spelled the end for most black communities. The All-Black towns were, for the most part, small agricultural centers that gave nearby African American farmers a market. Prosperity generally depended on cotton and other crops. The Great Depression devastated these towns, forcing residents to go west and north in search of jobs. These flights caused a huge population decrease in black towns.   As people left, the tax base withered, putting the towns in financial jeopardy. In the 1930s many railroads failed, isolating small towns and from regional and national markets. As a result, many of the black towns could not survive. During lean years whites would not extend credit to African Americans, creating an almost impossible situation for black farmers and businessmen to overcome .
