I'm not aware of an organization called "The National Association in Black History." It's possible that you may be referring to the National Association for the Advancement of Colored People (NAACP), which is one of the oldest and most prominent civil rights organizations in the United States. The NAACP was founded in 1909 and works to ensure the political, educational, social, and economic equality of rights of all persons and to eliminate race-based discrimination. If you have any specific questions about the NAACP or any other aspect of Black history, feel free to ask!
