Explanation:
The Brown v. Board of Education of Topeka was a landmark litigation or court case between Oliver Brown and the Board of Education in which the justices of the Supreme Court unanimously ruled (9-0) in 1954 that racially segregating children in public schools was unconstitutional because it violates the Equal Protection Clause of the Fourteenth Amendment (14th) of the Constitution of the United States of America.
