Hydraulic empire
A hydraulic empire (also known as a hydraulic despotism, or water monopoly empire) is a social or government structure which maintains power and control through exclusive control over access to water. It arises through the need for flood control and irrigation, which requires central coordination and a specialized bureaucracy.
Often associated with these terms and concepts is the notion of a water dynasty. This body is a political structure which is commonly characterized by a system of hierarchy and control often based on class or caste. Power, both over resources (food, water, energy) and a means of enforcement such as the military are vital for the maintenance of control.
Civilizations
A developed hydraulic civilization maintains control over its population by means of controlling the supply of water. The term was coined by the German American historian Karl August Wittfogel (1896–1988), in his book Oriental Despotism (1957). Wittfogel asserted that such "hydraulic civilizations" — although they were neither all located in the Orient nor characteristic of all Oriental societies — were essentially different from those of the Western world.
