Answer:
The Supreme Court's ruling in Brown v. Board of Education was a landmark decision that declared segregation in public schools unconstitutional. The Court's unanimous decision, announced on May 17, 1954, overturned the "separate but equal" doctrine established by Plessy v. Ferguson in 1896. The Court's ruling was a critical turning point in the Civil Rights Movement and served as a catalyst for ending segregation in all aspects of American society. It gave momentum to the movement for racial justice and paved the way for other important civil rights legislation, such as the Civil Rights Act of 1964 and the Voting Rights Act of 1965. The decision in Brown v. Board of Education was a pivotal moment in American history and helped advance civil rights by striking down the legal basis for racial segregation, and it remains a lasting symbol of the power of the judiciary to uphold the Constitution and protect individual liberties.
