I'm sorry, but there isn't an organization called "The National Association in Black history" that I am aware of. It is 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 well-known civil rights organizations in the United States. Founded in 1909, the NAACP has been instrumental in fighting for the rights of African Americans and other marginalized communities through legal advocacy, grassroots organizing, and public awareness campaigns. If you have a specific topic or question related to Black history or the NAACP, feel free to ask and I'll do my best to provide you with more information.
