Masonic conspiracy theories

Hundreds of conspiracy theories about Freemasonry 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).
