I'm sorry, but there is no widely known organization by the name of The Council on African American Affairs in Black history. It is possible that it is a lesser-known or more recent organization. However, there have been several important organizations throughout history that have advocated for the rights and advancement of African Americans, such as the NAACP (National Association for the Advancement of Colored People), the National Urban League, and the Southern Christian Leadership Conference, among others. If you have any more information about The Council on African American Affairs, I may be able to provide more insight.
