What was the court's opinion on Jim crow?

The court's opinion on Jim Crow laws, particularly as expressed in cases like Plessy v. Ferguson (1896), upheld the constitutionality of racial segregation under the "separate but equal" doctrine. The Supreme Court ruled that segregation did not violate the Equal Protection Clause of the Fourteenth Amendment, thereby legitimizing discriminatory practices that enforced racial inequality. This decision reinforced Jim Crow laws across the Southern United States until they were ultimately challenged and overturned in the mid-20th century.
