Answer:
court decision: Ruled that segregation violated the Fourteenth Amendment.
Legal precedent.: Overturned "separate but equal" as a legal practice.
Social impact: Gave force to the growing civil rights movement
Step-by-step explanation:
In Brown v. Board of Education of Topeka (1954), the Supreme Court ruled that racial segregation in public schools infringed the Fourteenth Amendment. By doing so, it overruled the Plessy v. Ferguson (1896) decision that claimed racial segregation under the “separate but equal” doctrine was constitutional.
By establishing a precedent about “separate-but-equal” education, as well as any other segregating practices, as not equal at all, Brown v. Board of Education became one of the pillars of the civil rights movement.
