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

In the Supreme Court case Plessy v. Ferguson (1896), the Court established the "separate but equal" doctrine, which became a legal foundation for racial segregation in the United States. This ruling upheld state laws that enforced segregation in public facilities under the premise that separate facilities for Black and white individuals were constitutional, provided they were equal in quality. The decision legitimized and encouraged the growth of Jim Crow laws that institutionalized racial discrimination, thereby entrenching segregation in various aspects of American life for decades. This ruling had lasting implications, contributing to systemic inequality and setting a precedent that was not overturned until the landmark Brown v. Board of Education decision in 1954, which declared that segregated schools were inherently unequal.
