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 in Des Moines, Iowa, by a group of African-American attorneys who were excluded from participating in the American Bar Association (ABA) due to racial segregation and discrimination.

The NBA was established to provide a platform for black lawyers to address the issues of racial inequality and discrimination within the legal profession and the broader society. Over the years, the NBA has been at the forefront of fighting for civil rights, social justice, and equality under the law for African Americans and other marginalized communities.

The NBA has played a significant role in advocating for racial justice, equality, and diversity in the legal profession, as well as in the larger society. The organization has also been instrumental in supporting and promoting the professional development of African-American lawyers and law students.

Through its advocacy efforts, legal initiatives, and educational programs, the National Bar Association has made a lasting impact on the legal profession and has helped to advance the cause of civil rights and social justice in America.
