On September 12, 1958, the Supreme Court issued a significant ruling in *Cooper v. Aaron*, ordering the integration of public schools in Little Rock, Arkansas. The decision was notable for its assertion that federal courts could enforce school desegregation despite state opposition and nullification claims. This case reinforced the authority of the U.S. Supreme Court over state governments regarding civil rights issues, particularly concerning racial segregation.
The 1954 landmark decision *Brown v. Board of Education* had already declared segregated schools unconstitutional, but enforcement lagged in many states. The Cooper v. Aaron ruling clarified that federal court orders must be obeyed by all levels of government and individuals within the United States.
