Conspiracy theories rely on the view that the universe is governed by design, and embody three principles: nothing happens by accident, nothing is as it seems, and everything is connected.
Favored subjects include famous deaths, government activities, new technologies, terrorism and questions of alien life.
Among the most widely recognized conspiracy theories are notions concerning the assassination of John F. Kennedy, the 1969 Apollo moon landings and the 9/11 terrorist attacks.
The most recent conspiracy theories refer to alleged plots for World domination by various groups both real and imaginary.
The theme has been often used in works of fiction, particularly in political fiction, as well as in conspiracy theories, particularly those fearing the development of a New World Order involving a World government of a totalitarian nature.
Some ideologies like Anarchism, Communism, Fascism, Nazism and Capitalism actively pursue this goal.
In certain religions, some adherents may also seek the peaceful or forced conversion of as many people as possible to their own religion, without restrictions of national or ethnic origin.
Spiritual domination is seen as distinct from the temporal dominion, although there have been instances of efforts begun as holy wars devolving into the pursuit of wealth, resources, and territory.
World domination can be achieved by establishing a hegemony or by direct military force. In the 4th century BCE, Alexander the Great notably expressed a desire to conquer the World.
