Desegregation cases refer to a series of legal battles in the United States aimed at ending the practice of racial segregation, particularly in public schools and facilities. These cases played a pivotal role in the expansion of the Civil Rights Movement, challenging discriminatory laws and practices that upheld racial inequality. Landmark decisions, such as Brown v. Board of Education, not only dismantled legal segregation but also galvanized activists and provided momentum for broader civil rights advancements.
