What was the outcome of the plessy vs furguson case and what made it important?

The Plessy vs Furguson was a landmark constitutional law case of the U.S. supreme court. The significance was that Plessy legitimized the state laws establishing racial segregation in the South and provided a movement towards further segregation laws . It also legitimized laws in the North requiring racial segregation as in the Boston school segregation case noted by Justice Brown in his majority opinion .The ruling basically granted states legislative immunity when dealing with questions of race, guaranteeing the states right to implement racially separate institutions, requiring them only to be "equal".
