Which was an effect of the Supreme Court case Plessy v. Ferguson?

One of the major effects of the Supreme Court case Plessy v. Ferguson was the establishment of the "separate but equal" doctrine, which allowed for state-sanctioned racial segregation. This decision upheld the constitutionality of racial segregation as long as separate facilities were provided for different races, even if they were unequal in quality. Plessy v. Ferguson further legitimized and institutionalized racial discrimination, leading to the implementation of Jim Crow laws and the continued oppression of African Americans for several decades. It was not until the landmark case Brown v. Board of Education in 1954 that the "separate but equal" doctrine was overturned.
