name

• (Roman Catholicism, historical, often capitalized) The period of the papacy known as the saeculum obscūrum (Latin for “dark age”), and also as the “Rule of the Harlots”, which began with the installation of Pope Sergius III in 904 and lasted for sixty years until the death of Pope John XII in 964, during which time the popes were strongly influenced by the Theophylacti, a powerful and corrupt aristocratic family.
  "Under the pornocracy (government of harlots) in the first half of the 10th century, the Papacy was degraded and all Italy torn by factions."

noun

• (derogatory, often figuratively) A government by, or dominated by, prostitutes or corrupt persons.
  "[Pierre-Joseph] Proudhon had a consistent—many have called it reactionary—preference for smaller and more personalized social units. His passionate defense of the traditional rural family (and attendant hatred of the “pornocracy” of Paris) was part of a relentless localism that tended to prefer Burgundy to France, Franche Comité to Burgundy, and the individual family and village to Franche Comité."
• (derogatory) A societal culture dominated by pornography.
  "If the 'meritocrat' – the 'natural' aristocrat whose success is not beholden to class or background – was a key component in the 1970s mythology, was the pornocrat the 1970s cold-light-of-day equivalent? And if the pornocrat was such a key player and empire builder, does that imply the evolution of a fully fledged pornocracy, a culture organised around the economic logic of pornography? […] The pornocrat controls and selectively distributes sexual capital – thus obscenity laws both help and hinder him – knowledge, 'freedom', sexual technology, the means of stimulation and success. The pornocracy is essentially inhabited by two classes – there are the pornocrats themselves and the swinging elite surrounding them and there are the 'punters' over whom they rule benevolently."

name

• (Roman Catholicism, historical) Alternative letter-case form of pornocracy.
  "Monsters of impurity, avaricious wretches, poisoners, have occupied the papal see. A learned bishop (Maret of the General Council) expresses himself with holy indignation in reference to the frightful enormities of the tenth century. This epoch deserves to be designated under the title of the Pornocracy; that is to say, the governmentof prostitutes, for Theodora, Marozia, and other ladies of rank at that time, placed on the pontifical throne their paramours and their sons, who were no better than themselves."
