The Order of the Nine Angles (ONA) is a clandestine esoteric organization and satanic occult movement that emerged in the United Kingdom during the late 1960s and early 1970s. Publicly identified through scattered writings and a network of autonomous cells, it is widely considered one of the most extreme and controversial groups within modern occultism, having influenced both radical satanic ideologies and, according to counterterrorism experts, certain neo-fascist accelerationist movements. Historical Emergence and Key Figure The ONA was largely shaped by the writings of a British national using the pseudonym Anton Long , who published hundreds of texts between the late 1970s and early 2000s. Long claimed to have been initiated into a tradition called the "Traditionalist Sinister" or "Tempel ov Blood." Scholars generally place the ONA’s formal emergence in the Shropshire/West Midlands region of England, though the group insists on a much older, pre-Christian heritage tracing back to ancient Hyperborea.
