The case of Plessy versus Ferguson was a decision in the series of Supreme Court cases dealing with Jim Crow laws, the laws dealing with racial segregation, and whether or not the idea of seperate but equal was constitutional. Justice Brown, in his decision explained to the court that Plessies arguments about the Louisiana law forcing blacks and whites to ride in seperate cars on trains was unconstitutional was wrong. The court beleived that the law was not in conflict with the thirteenth ammendment because forcing blacks to ride on seperate trains was not slavery, what the thirteenth banned. Slavery was involuntary servitude, and the Louisiana law was forcing no involuntary servitude. The fourteenth ammendment says all people naturalized to the :United States, or people born here are all considered citizens. Plessy claimed that he was being deprived of citizenship, because property was considered part of citizenship. Homer Plessy was seven eighths white, and he beleived being white was property, because it was something he inherited that was good, but the court considered him black, even though his reputation was for being a white man, and visibly he looked white.
