King v. Chapman is a 1945 court case between Primus King, a religious leader and barber in Columbus, Georgia, and J. E. Chapman, Jr., the chair of the Muscogee County Democratic Party. It ruled the white primary as used by the Democratic Party of Georgia to be unconstitutional.[1] This case followed the Smith v. Allwright case, which struck down the white primaries in Texas and began the downfall of white primaries in other Deep South states.
