Masonic conspiracy theories
Masonic conspiracy theories are conspiracy theories involving Freemasonry; hundreds of such conspiracy theories have been described since the late 18th century. Usually, 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 theories have connected the Freemasons (and the Knights Templar) with worship of the devil; these ideas are based on different interpretations of the doctrines of those organizations. Of the claims that  Freemasonry exerts control over politics, perhaps the best-known example is the New World Order theory, but there are others. These mainly involve aspects and agencies of the United States government, but actual events outside the US (such as the Propaganda Due scandal in Italy) are often used to lend credence to claims. Another set of theories has to do with Freemasonry and Religion, particularly that Freemasonry deals with "the occult". These theories have their beginnings in the Taxil hoax. In addition to these, there are various theories that focus on the embedding of symbols in otherwise ordinary items, such  as street patterns, national seals, corporate logos, etc. There are Masonic conspiracy theories dealing with every aspect of society. The majority of these theories are based on one or more of the following assumptions: List of conspiracy theories associated with Freemasonry.
