Explanation:

• Brown v. Board of Education was a landmark 1954 U.S. Supreme Court case that overturned the "separate but equal" doctrine established in Plessy v. Ferguson, ruling state-mandated racial segregation in public schools unconstitutional.
• The Southern Manifesto was a 1956 document by Southern lawmakers opposing the Brown v. Board decision, not a ruling against segregation.
• Plessy v. Ferguson (1896) upheld racial segregation under the "separate but equal" principle, which the Brown case reversed.
• Arkansas public schools were the site of enforcement conflicts after the Brown decision, not the entity that made the ruling.

A. Brown v. Board of Education
