Explanation:

In Plessy v. Ferguson the U.S. Supreme Court confirmed the constitutionality of racial segregation following the separate but equal principle, after Homer Plessy, an African American refused to sit in the train car destined for black people. Consequently, the discriminatory Jim Crow legislation and separate public places became stronger.

The Supreme Court's ruling in Brown v. Board of Education (1954) ruled that state laws establishing separate public schools for black and white students were a violation of the Equal Protection Clause of the Fourteenth Amendment of the United States Constitution.
