What was the significance of the Supreme Court case Plessy v. Ferguson?

The significance of the Supreme Court case Plessy v. Ferguson lies in its establishment of the "separate but equal" doctrine, which upheld the constitutionality of racial segregation. In this landmark 1896 decision, the Court ruled that state laws requiring racial segregation in public facilities did not violate the Equal Protection Clause of the Fourteenth Amendment, as long as the separate facilities were equal in quality. This ruling provided a legal foundation for the continued implementation of segregation laws across the United States and effectively legitimized systemic racism for decades. It wasn’t until the mid-20th century, particularly with the Brown v. Board of Education decision in 1954, that the principles established in Plessy v. Ferguson were fundamentally challenged and overturned. The legacy of this case illustrates how legal interpretations at the highest level can shape social policies and public attitudes toward race and equality.
