I'm not familiar with an organization called "The National Association in Black history." It is possible that you may be referring to the National Association for the Advancement of Colored People (NAACP), which is a prominent civil rights organization founded in 1909 that works to fight for social justice and equality for African Americans and other marginalized communities. If you have a specific organization or topic in mind related to Black history, please provide more information so I can assist you better.
