Answer:
In Brown vs Board of Education, the supreme court ruled that black students cannot be segregated from white students because segregation represents a violation of the fourteenth amendment, which establishes equal legal rights for all people, regardless of sex, gender, race or origin.
Before Brown vs Board of Education, schools were segregated under the justification that black people and white people were separate, but equal. This means that if a black school is not worse in terms of qualities and facilities than a white school, then, the black school is achieving its purpose of educating black children, and black children are being protected under the 14th amendment.
Brown vs Board of Education overulled previous decisions in this topic. It relates to the concept of civil rights in that non-segregated education for black people is one of their civil rights, and with Brown vs Board of Education, this right became constitutionally protected.
