• Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
  • All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
  • All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE. PAGES WILL BE DELETED OTHERWISE IF THEY ARE MISSING BASIC MARKUP.

There are three basic kinds of conspiracies, though the borders between them are fluid:

The Conspiracy is generally a great antagonist in any story but two genres make a particularly extensive use of it:

For further tips on writing both of the above, see Write a Conspiracy Theory. For tropes commonly associated with conspiracies, see The Index Is Watching You.

Multiple concurrent conspiracies form a Conspiracy Kitchen Sink. A character believing in conspiracies is a Conspiracy Theorist. See also Milkman Conspiracy and Conspiracy Religion.

Examples of works/series featuring conspiracies of more than one type:

Anime & Manga


Tabletop Games

  • Eclipse Phase has Firewall, a "heroic" (well, anti-heroic) conspiracy that does not work for any government or criminal organization, and is devoted to the survival of transhumanity at all costs. Though there's also Project Ozma, SETI turned MIB.
  • GURPS Illuminati is an invaluable resource for conspiracy-related games in general.

Video Games

Web Comics


  • The Church Of The Sub Genius blames pretty much everything wrong with the world on "The CONSPIRACY" (which is apparently an acronym for "Cliques Of Normals Secretly Planning Insidious Rituals Aimed At Controlling You").
