Majestic 12 (also known as MJ-12 or Majic 12) is the name of a purported secret committee of scientists, military leaders, and government officials formed in 1947 by an executive order of U.S. President Harry S. Truman. According to conspiracy lore, the group was established in the wake of the Roswell UFO incident, with the mission to recover and investigate crashed alien spacecraft and manage extraterrestrial contact.

The existence of Majestic 12 was first revealed to the public in the 1980s through a series of leaked documents, including a classified briefing paper addressed to President-elect Dwight D. Eisenhower. These documents described MJ-12 as a highly classified, above-top-secret group with full access to information on extraterrestrial technology and beings.

Skeptics argue that the MJ-12 documents are forgeries, possibly created as disinformation during the Cold War or by UFO enthusiasts. The FBI investigated the documents and officially deemed them “completely bogus.” Despite this, many in the UFO community continue to believe MJ-12 was (or is) real, suggesting that the group may have evolved over time into other secretive entities within the intelligence or defense establishment.

Majestic 12 has become a cornerstone of modern UFO mythology, inspiring books, documentaries, and conspiracy theories. Whether real, disinformation, or fiction, the idea of MJ-12 continues to fuel speculation about a hidden government agenda concerning extraterrestrial life.
