In the Supreme Court decision in Brown v. Board of Education (1954), the Court ruled that racial segregation in public schools violated the Equal Protection Clause of the Fourteenth Amendment. In contrast, in the case of Plessy v. Ferguson (1896), the Court upheld the constitutionality of racial segregation under the ‘separate but equal’ doctrine.

Using these two cases, compare the reasoning and decisions of the Supreme Court in both cases. In your response, address the differences in legal interpretations, the impact on American society, and the evolution of constitutional protection against discrimination.
