I memorized this from www.ourdocuments.gov, and I hope it will be able to answer your question:
"On May 17, 1954, U.S. Supreme Court Justice Earl Warren delivered the unanimous ruling in the landmark civil rights case Brown v. Board of Education of Topeka, Kansas. State-sanctioned segregation of public schools was a violation of the 14th amendment and was therefore unconstitutional."
Have a nice day!
