Brown v. Board of Education of Topeka was a case decided in 1954 in which the Supreme Court of the United States declared racial segregation in public schools to be unconstitutional. The full name of the case is Brown et al v. Board of Education of Topeka, Shawnee County, Kansas.

The Supreme Court's decision launched the legal movement to desegregate U.S. society. At that time, many areas of the United States, especially in the South, were racially segregated. In segregated areas, blacks and whites went to separate schools, lived in separate neighborhoods, rode in separate parts of buses, and drank from separate drinking fountains. State laws called Jim Crow laws required or permitted such separation. An 1896 Supreme Court decision in the case of Plessy v. Ferguson had permitted separate railroad cars or trains as long as they were equal in nature. The 1896 decision established the "separate but equal" principle, which later was used to uphold other kinds of segregation in the United States.

The National Association for the Advancement of Colored People, guided by its chief lawyer, Thurgood Marshall, decided to use the Brown case and its companion cases to challenge the "separate but equal" principle. In the Brown case itself, Oliver Brown, an African American railroad worker in Topeka, Kansas, sued the Topeka Board of Education for not allowing Linda Brown, his daughter, to attend Sumner Elementary School, an all-white school near her home.

Marshall attacked the "separate but equal" rule by arguing that segregation harms minority students by making them feel inferior and thus interfering with their ability to learn. In a unanimous decision, the court agreed with Marshall and declared that separate educational facilities could never be equal. Therefore, segregated schools violated the 14th Amendment to the Constitution of the United States, which requires that all citizens be treated equally.
