The civil rights movement in Black history made significant advancements through the courts. One landmark case was Brown v. Board of Education in 1954, where the Supreme Court ruled that segregation in public schools was unconstitutional. This decision overturned the "separate but equal" doctrine established in Plessy v. Ferguson (1896) and laid the groundwork for desegregation in all areas of society.

Another crucial court case was Loving v. Virginia in 1967, where the Supreme Court struck down laws banning interracial marriage. This decision was a significant victory for civil rights and challenged discriminatory practices based on race.

Additionally, the Civil Rights Act of 1964 and the Voting Rights Act of 1965 were instrumental in advancing civil rights through legislation. These laws prohibited discrimination based on race in public accommodations, employment, and voting rights, providing legal remedies for individuals facing discrimination.

Overall, the courts played a critical role in shaping the civil rights movement in Black history by challenging unjust laws and policies that perpetuated racial inequality and discrimination.
