Brown v. Board of Education Ends School Segregation
On May 17, 1954, the United States Supreme Court handed down a unanimous decision in Brown v. Board of Education of Topeka, Kansas, declaring racial segregation in public schools unconstitutional. The ruling overturned the 1896 Plessy v. Ferguson decision, which had upheld the "separate but equal" doctrine for nearly six decades. Chief Justice Earl Warren wrote that separate educational facilities were "inherently unequal," dealing a landmark blow to the legal architecture of Jim Crow. The decision did not immediately end segregation, triggering fierce resistance across the South, but it became the legal cornerstone of the American civil rights movement and inspired decades of activism. Its moral authority reverberated far beyond schools, reshaping what equal citizenship meant in America.
