The National Bar Association (NBA) is the oldest and largest association of predominantly African-American lawyers and judges in the United States. It was founded in 1925 during a time when African-American attorneys were routinely excluded from membership in the American Bar Association (ABA) and other professional organizations.

The NBA was established to provide opportunities for African-American lawyers to network, support each other, and advocate for civil rights and social justice issues within the legal profession. Over the years, the NBA has been instrumental in advocating for diversity and inclusion in the legal profession, fighting for civil rights, and promoting equal justice under the law.

The NBA has been involved in landmark legal cases, including Brown v. Board of Education, which overturned the doctrine of "separate but equal" in public schools. The organization also played a key role in the civil rights movement, providing legal support to activists and fighting against racial discrimination in the legal system.

Today, the National Bar Association continues to be a powerful voice for African-American lawyers and a leading advocate for justice and equality. It provides professional development, networking opportunities, and support for its members, while also working to advance civil rights and social justice issues in the United States and around the world.
