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 the American Bar Association due to racial discrimination.

The NBA was formed to address the limited opportunities for African-American lawyers and to fight against racial segregation and discrimination in the legal profession. Over the years, the NBA has been instrumental in advocating for civil rights and social justice issues, promoting diversity in the legal field, and providing resources and support for African-American attorneys.

The NBA has played a significant role in advancing the cause of civil rights, including participating in legal battles to end segregation and discrimination in schools, housing, and public accommodations. The association has also been involved in advocating for criminal justice reform, voting rights, and economic empowerment in the African-American community.

Today, the National Bar Association continues to be a powerful voice for African-American legal professionals and a leading advocate for racial equality and social justice in America. The NBA's legacy in Black history highlights the ongoing struggle for equal rights and opportunities for African-Americans in the legal profession and society as a whole.
