This Day in History: Brown v. Board

In this milestone decision, the Supreme Court ruled that separating children in public schools on the basis of race was unconstitutional. It signaled the end of legalized racial segregation in the schools of the United States, overruling the "separate but equal" principle set forth in the 1896 Plessy v. Ferguson case.

On May 17, 1954, U.S. Supreme Court Justice Earl Warren delivered the unanimous ruling in the landmark civil rights case Brown v. Board of Education of Topeka, Kansas. State-sanctioned segregation of public schools was a violation of the 14th amendment and was therefore unconstitutional. This historic decision marked the end of the "separate but equal" precedent set by the Supreme Court nearly 60 years earlier in Plessy v. Ferguson and served as a catalyst for the expanding civil rights movement during the decade of the 1950s.
