Brown v. Board Ends Segregation: Schools Must Be Equal

Nine Supreme Court justices spoke with one voice on May 17, 1954, and dismantled the legal architecture of American racial segregation. Chief Justice Earl Warren, reading the unanimous opinion in Brown v. Board of Education, declared that "separate educational facilities are inherently unequal" and that segregated schools violated the Fourteenth Amendment's guarantee of equal protection under the law. The decision overturned Plessy v. Ferguson, which had sanctioned "separate but equal" doctrine for fifty-eight years. The case consolidated five lawsuits from Kansas, South Carolina, Virginia, Delaware, and Washington, D.C., each challenging segregated public schools. Thurgood Marshall, chief counsel for the NAACP Legal Defense Fund, argued that segregation inflicted psychological harm on Black children, citing studies by psychologists Kenneth and Mamie Clark showing that Black children in segregated schools preferred white dolls over brown ones. Warren's opinion incorporated this social science evidence, a controversial legal strategy that gave critics grounds to attack the decision's reasoning. Warren's achievement of unanimity was itself remarkable. Several justices had initially been inclined to uphold segregation or issue a fractured opinion. Warren, appointed just months earlier after Chief Justice Fred Vinson's death, spent weeks personally lobbying his colleagues. He argued that a divided court would give southern states room to resist. Justice Stanley Reed, the last holdout, finally agreed to join the unanimous opinion after Warren appealed to him directly. The decision triggered massive resistance across the South. Over a hundred southern members of Congress signed the "Southern Manifesto" denouncing the ruling. Virginia closed entire school districts rather than integrate. Arkansas Governor Orval Faubus called out the National Guard to block Black students from entering Little Rock's Central High School in 1957, forcing President Eisenhower to deploy the 101st Airborne Division. Full implementation took decades, but Brown established the constitutional principle that separate could never be equal.
