Syndicate (The X-Files)

The Syndicate is a "shadow government" group featured in The X-Files television show and feature film created by Chris Carter. They were also known as The Elders, The Consortium, and The Group. Because of their presiding over the cover-up of extraterrestrial life, they were the primary antagonistic force opposing Dana Scully, Fox Mulder, John Doggett, and Monica Reyes during the series.

An embodiment of the concept of the "shadow government" in conspiracy theory lore, the Syndicate is composed of covertly allied influential government officials and businessmen. The Syndicate, operating at the highest levels of power, concealed from the world a program by an unidentified extraterrestrial species to colonize and repopulate the planet, as well as their own plans and stake in that future, which they held to be inevitable.

To carry out murder, cover-ups, sabotage and other wetworks projects, the Syndicate used an unknown number of henchmen commonly referred to as the Men in Black. The Men in Black were merciless protectors of the conspiracy whose true names, like the members of the Syndicate, were rarely if ever known. Many worked ostensibly for the U.S. Defense Department, Central Intelligence Agency, National Security Agency, along with various other government agencies. Prominent Men in Black agents included X, Alex Krycek, the Crew Cut Man, and Quiet Willy.
