The National Bar Association (NBA) is the oldest and largest national network of predominantly African American attorneys and judges in the United States. It was founded in 1925 in Des Moines, Iowa, by a group of 31 African American lawyers who were denied membership in the American Bar Association due to racial discrimination at the time.

The NBA was established to promote equal justice and eliminate racial disparities in the legal profession. It has played a significant role in advocating for civil rights, desegregation, and equal access to justice for African Americans and other marginalized communities. The organization has also been instrumental in addressing issues of police brutality, voting rights, and criminal justice reform.

Over the years, the NBA has been at the forefront of advocating for diversity and inclusion in the legal profession, as well as advancing the professional development and success of African American lawyers and judges. The organization provides networking opportunities, continuing legal education, and leadership development programs for its members.

The National Bar Association continues to be a powerful voice for social justice and equality in the United States, and its members have made significant contributions to the advancement of Black Americans in the legal field and beyond.
