the goal of some internationalists for centuries. William Penn, the founder of the Quakers, had a plan for a world government, as did the eighteenth century German philosopher Immanuel Kant. The world rule of the proletariat also plays a part in Marxism. But the idea of one world government has never been a serious possibility; the strength of nationalism and the rivalry of different economic and social systems would seem to make it impractical. In spite of this, conspiracy theorists today believe that a plot to create a world government, involving the United Nations, international bankers, and sections of the U.S. government, is well advanced.

World government is the concept of a political body that would make, interpret, and enforce international law. Inherent to the concept of a world government is the idea that nations would be required to pool or surrender (depending on point of view) sovereignty over some areas. In effect, a world government would add another level of administration above the existing national governments or provide coordination over areas national governments are not capable of adequately addressing as independent polities.

The World Government (世界政府, Sekai Seifu) is a fictional political organization, in the Japanese manga and anime series One Piece.
