The political strategy used to eliminate discrepancies between Black Americans and American ideals through the Brown v. Board of Education case is best described as:
Interest groups litigated unfair laws in the Supreme Court.
This approach involved civil rights organizations, such as the NAACP (National Association for the Advancement of Colored People), using the judiciary to challenge and overturn laws that enforced racial segregation and discrimination, thus seeking to secure equal protection under the law as guaranteed by the Fourteenth Amendment. The case served as a pivotal moment in the civil rights movement, illustrating the use of legal strategies to combat inequality.
