I'm sorry, but there is no specific organization called "The National Association in Black history." However, there are several well-known organizations that are dedicated to preserving, promoting, and celebrating Black history and culture. Some examples include the Association for the Study of African American Life and History (ASALH), the National Museum of African American History and Culture, and the National Association for the Advancement of Colored People (NAACP). If you meant a different organization or have a specific topic in mind, please let me know so I can provide you with more accurate information.
