Topics: Civics, Civil Rights, Civilization, Existentialism, Fascism, History “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. This historic decisionContinue reading “Seventy Years Ago…”
