Conspirators' Hierarchy: The Story of the Committee of 300 by Dr. John Coleman is a foundational conspiracy theory book that alleges a secret, elite group controls global politics, finance, and social engineering. Coleman claims that a 300-member body (the "Committee of 300")—comprising royalty, bankers, and corporate leaders, primarily from Britain and the US—is working to destroy national sovereignty and establish a neo-feudal "One World Government". Dr. John Coleman describes himself as a former British intelligence officer who, through his research and investigations, uncovered this "invisible government." The book, which has had several editions and revisions, is written in a style that often links diverse events to this centralized, behind-the-scenes power structure.
