World domination

World domination (also called global domination or world conquest or cosmocracy) is a hypothetical power structure, either achieved or aspired to, in which a single political authority holds the power over all or virtually all the inhabitants of Earth. Various individuals or regimes have tried to achieve this goal throughout history, without ever attaining it. The theme has been often used in works of fiction, particularly in political fiction, as well as in conspiracy theories (which may posit that some person or group has already secretly achieved this goal), particularly those fearing the development of a "New World Order" involving a world government of a totalitarian nature.
