I'm not aware of an organization specifically called The National Association in Black history. However, a prominent and influential organization in Black history is the National Association for the Advancement of Colored People (NAACP). The NAACP was founded in 1909 and has been one of the most significant civil rights organizations in the United States. Its mission is to ensure the political, educational, social, and economic equality of rights for all persons and to eliminate race-based discrimination. The NAACP has played a key role in landmark civil rights cases, such as Brown v. Board of Education, and continues to advocate for racial justice and equality today.
