I'm sorry, but there is no widely recognized 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 to fight for the rights of African Americans. The NAACP has played a crucial role in advocating for civil rights, social justice, and equal opportunities for black Americans. If you have any other specific topic or organization in mind related to Black history, please let me know so I can provide accurate information.
