Long after the Brown v. Board of Education decision, some states had not desegregated their schools because the Supreme Court had not set a deadline for doing so.

Segregation is a deprivation of the Equal Protection of the Laws guaranteed by the 14th Amendment.

Explanation: "In the intervening year, the District of Columbia and some school districts in other states had voluntarily begun to desegregate their schools. However, state-sanctioned opposition to desegregation was already well under way in Alabama, Georgia, Mississippi, South Carolina, and Virginia, where the Court's decision had been declared "null, void, and no effect." Across the South, schools were closed and public education was suspended. Public funds were disbursed to parents to subsidize the education of their children in private schools. Some states even went so far as to impose sanctions on anyone who implemented desegregation." (archives.gov)
