I'm sorry, but there is no specific organization or entity known as The National Association in Black history. However, there are several prominent organizations in the United States dedicated to celebrating and preserving Black history, such as the Association for the Study of African American Life and History (ASALH) and the National Museum of African American History and Culture.

ASALH was founded by Carter G. Woodson in 1915 and is the organization responsible for establishing Black History Month in the United States. The National Museum of African American History and Culture is part of the Smithsonian Institution and opened in 2016, showcasing the history and contributions of African Americans to American society.

These organizations, along with countless others, work tirelessly to promote the understanding and appreciation of Black history and culture in America and beyond.
