What did the plessy v Ferguson create?

The Plessy v. Ferguson decision in 1896 established the legal doctrine of "separate but equal," which upheld racial segregation in public facilities. The Supreme Court ruled that racial segregation did not violate the Equal Protection Clause of the Fourteenth Amendment, legitimizing discriminatory laws across the United States. This decision provided a constitutional basis for segregation and discrimination, leading to widespread injustices and the entrenchment of Jim Crow laws until it was eventually overturned by Brown v. Board of Education in 1954.
