Majestic 12, also known as Majic-12, and MJ-12 for short, is a purported organization that appeared in fake documents first circulated by ufologists in 1984, and that some UFO conspiracy theories still claim to have existed. The organization is claimed to be the code name of an alleged secret committee of scientists, military leaders, and government officials, formed in 1947 by an executive order by U.S. President Harry S. Truman to facilitate recovery and investigation of alien spacecraft. The Federal Bureau of Investigation (FBI) declared the documents to be "completely bogus", and many ufologists consider them to be an elaborate hoax.[1][2] Majestic 12 remains popular among some UFO conspiracy theorists and the concept has appeared in popular culture including television, film, video games, and literature.
