what is the significance of the supreme court’s decision in brown? How does that pave the way for civil rights laws after its ruling

The Supreme Court decision in Brown v. Board of Education, pronounced in 1954, was one of the major milestones during African Americans' fight for their civil rights in the 1900s. Through this ruling, the Supreme Court established that the schools in the south of the country should be desegregated, that is, that black and white children had an equal right of access to education, without any racial distinction, and that the doctrine of "Separate but equal" was inherently discriminatory as it offered services of different quality depending on whether the person was white or black.

This ruling was one of the first demonstrations at the federal level against segregation in the south of the country, prompting the Civil Rights Movement to continue fighting for equality.
