In 1950, members of the Topeka, Kansas, Chapter of the NAACP (National Association for the Advancement of Colored People) challenged the "separate but equal" doctrine governing public education through a class action suit when they were denied the opportunity to enroll their children in the white-only schools. When the Topeka case made its way to the United States Supreme Court it was combined with other NAACP cases from Delaware, Virginia, South Carolina and Washington, D.C. The combined cases became known as Oliver L. Brown et. al. vs. The Board of Education of Topeka (KS). On May 17, 1954 the Supreme Court issued a unanimous decision overturning "separate but equal" as unconstitutional, stating that segregation in public schools was a violation of the 14th Amendment.
