 This was a more direct and potentially more rapid means of creating change than the traditional approach of mounting court challenges used by the NAACP and others.In 1952, the Regional Council of Negro Leadership (RCNL), led by T. R. M. Howard, a black surgeon, entrepreneur, and planter organized a successful boycott of gas stations in Mississippi that refused to provide restrooms for blacks.Through the RCNL, Howard led campaigns to expose brutality by the Mississippi state highway patrol and to encourage blacks to make deposits in the black-owned Tri-State Bank of Nashville which, in turn, gave loans to civil rights activists who were victims of a "credit squeeze" by the White Citizens' Councils.
