Which landmark Supreme Court case declared segregation in public schools unconstitutional?

The landmark Supreme Court case that declared segregation in public schools unconstitutional is Brown v. Board of Education. Decided in 1954, this unanimous ruling overturned the earlier precedent set by Plessy v. Ferguson, which had established the "separate but equal" doctrine. The Court found that segregating children in public schools solely on the basis of race created a sense of inferiority that could affect their hearts and minds in a way unlikely ever to be undone. As a result, the ruling emphasized that educational facilities must be available to all children on equal terms, thus declaring state laws establishing separate public schools for black and white students to be unconstitutional. This decision was a significant catalyst in the Civil Rights Movement, leading to increased efforts to challenge segregation in all areas of public life.
