Brown v. Board of Education of Topeka, 347 U.S. 483 (1954), was a landmark decision of the U.S. Supreme Court that ruled that U.S. state laws establishing racial segregation in public schools are unconstitutional, even if the segregated schools are otherwise equal in quality. The decision partially overruled the Court's 1896 decision Plessy v. Ferguson, which had held that racial segregation laws did not violate the U.S. Constitution as long as the facilities for each race were equal in quality, a doctrine that had come to be known as "separate but equal". The Court's unanimous decision in Brown, and its related cases, paved the way for integration and was a major victory of the civil rights movement, and a model for many future impact litigation cases.

The case began in 1951 when the public school system in Topeka, Kansas, refused to enroll the daughter of local black resident Oliver Brown at the school closest to their home, instead requiring her to ride a bus to a segregated black school farther away. The Browns and twelve other local black families in similar situations filed a class-action lawsuit in U.S. federal court against the Topeka Board of Education, alleging its segregation policy was unconstitutional. A special three-judge court of the U.S. District Court for the District of Kansas heard the case and ruled against the Browns, relying on the precedent of Plessy and its "separate but equal" doctrine. The Browns, represented by NAACP chief counsel Thurgood Marshall, appealed the ruling directly to the Supreme Court. (Full article...)
