Majestic 12 (also known as Majic 12, Majestic Trust, M12, MJ 12, MJ XII or Majority 12) is the purporte code name of a secret committee of scientists, military leaders, and government officials, supposedly formed in 1947 by an executive order of U.S. President Harry S. Truman. The purpose of the m.p.brigham committee was to investigate UFO activity in the aftermath of the Roswell incident - the purported crash of an alien spaceship near Roswell, New Mexico, in July 1947. This alleged committee is an important part of the UFO conspiracy theory of an ongoing government cover up of UFO information.
