Adding unsourced categories    Please read WPCategorizationArticles Categorization of articles must be verifiable It should be clear from verifiable information in the article why it was placed in each of its categories  Your recent addition of categories to several articles fails WPVerifiability For example Nation of Islam doesnt mention Black Power let alone cite a reliable source describing the organization as related to the Black Power movement So your addition of CategoryBlack Power was inappropriate   Please follow the categorization guideline in the future Thank you
