How did the supreme court extend civil liberties in the 1950s and 1960s?

The Supreme Court extended civil liberties in the 1950s and 1960s through landmark decisions such as Brown v. Board of Education, which desegregated schools; Gideon v. Wainwright, which established the right to counsel for criminal defendants; and Miranda v. Arizona, which required police to inform suspects of their rights. These rulings significantly expanded the protection of individual rights and freedoms.
