 The National Association for the Advancement of Colored People (NAACP) was founded in 1909.It fought to end race discrimination through litigation, education, and lobbying efforts.Its crowning achievement was its legal victory in the Supreme Court decision "Brown v. Board of Education" (1954), when the Warren Court ruled that segregation of public schools in the US was unconstitutional and, by implication, overturned the "separate but equal" doctrine established in "Plessy v. Ferguson" of 1896.
