Masonic conspiracy theories are
conspiracy theories involving
Freemasonry; hundreds of such conspiracy theories have been described since the late 18th century. Generally, these theories fall into three distinct categories: political (usually involving allegations of control of government, particularly in the
United States and the
United Kingdom), religious (usually involving allegations of anti-Christian or Satanic beliefs or practices), and cultural (usually involving popular entertainment). Many conspiracy theory writers have connected Freemasons (and the
Knights Templar) with worship of the devil; these ideas are based on different interpretations of the doctrines of those organizations.
