The landmark decision made in the case of Brown v. Board of Education in 1954 declared that racial segregation in public schools was unconstitutional. The Supreme Court ruled unanimously that "separate but equal" educational facilities were inherently unequal, violating the Equal Protection Clause of the Fourteenth Amendment. This landmark ruling overturned the precedent set by Plessy v. Ferguson in 1896, which upheld segregation. The Brown decision was a significant victory for the Civil Rights Movement, providing legal justification for challenging segregation and discrimination. This case was foundational in the fight for educational and social equality, spurring further actions toward desegregation across the United States.
