Most of the first civilizations in history, such as Ancient Egypt, Sri Lanka, Mesopotamia, China and pre-Columbian Mexico and Peru, are believed to have been hydraulic empires. The Indus Valley civilization is often considered a hydraulic empire despite a lack of evidence of irrigation (as this evidence may have been lost in time due to flood damage). Most hydraulic empires existed in desert regions, but imperial China also had some such characteristics, due to the exacting needs of rice cultivation.
The typical hydraulic empire government, in Wittfogel's thesis, is extremely centralized, with no trace of an independent aristocracy -- in contrast to the decentralized feudalism of medieval Europe. Though tribal societies had structures that were usually personal in nature, exercised by a patriarch over a tribal group related by various degrees of kinship, hydraulic hierarchies gave rise to the established permanent institution of impersonal government. Popular revolution in such a state was impossible: a dynasty might die out or be overthrown by force, but the new regime would differ very little from the old one. Hydraulic empires were only ever destroyed by foreign conquerors.
Wittfogel's ideas, when applied to China, have been harshly criticized by scholars such as Joseph Needham who argued essentially that Wittfogel was operating from ignorance of basic Chinese history. Needham argued that the Chinese government was not despotic, was not dominated by a priesthood, and that Wittfogel's perspective does not address the necessity and presence of bureaucracy in modern Western civilization.
Perhaps the most familiar example is Frank Herbert's Dune series. The spice mélange produced by sandworms is essential for prolonging human lifespan, faster-than-light travel, and a form of precognition ability. A saying used within the books is "He who controls the spice, controls the universe!"
Larry Niven has a variation of a hydraulic empire in most of his fictional universes:
The 2007 Flash Gordon TV series depicts Mongo under the rule of Ming as a hydraulic empire. All water on Mongo is toxic grey water, which induces mutations in all those who drink it, except for a single source of clean source water controlled by Ming, the distribution of which is used as leverage over the other cantons.
In the film Mad Max Beyond Thunderdome, Bartertown is nominally led by "Aunty Entity", who leads the town's militia, but the dwarf "Master", who runs the underground methane refinery, begins to realize that he wields the true power since all of Bartertown's technology depends on him, and begins to impose "embargoes", challenging Auntie's leadership.
In the film version of Tank Girl, the remaining supply of fresh water on a dystopian Earth is controlled by an organization known simply as "Water and Power.
In the milieu of the British comic book Judge Dredd, the Moon colonists are governed by "The Oxygen Board", a ruthless public utility that shuts off the air supply to delinquent account holders. Similarly, a ruthless administrator uses his control of the Mars colony's air supply to put down challenges to his rule in the film Total Recall.
