`  == Adding unsourced categories  ==  Please read WP:Categorization#Articles. ``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 WP:Verifiability. For example, Nation of Islam doesn't mention Black Power, let alone cite a reliable source describing the organization as related to the Black Power movement. So your addition of Category:Black Power was inappropriate.   Please follow the categorization guideline in the future. Thank you.   `
