What is "nikephoritzes"

Nikephoritzes was an influential Byzantine eunuch official, who served as chief minister and virtual ruler of the Byzantine Empire during the reign of Emperor Michael VII Doukas (r. 1071–1078). His actual name was Nikephoros; he received the nickname "Nikephoritzes" ("little Nikephoros") as a result of his relative youth when he first entered service in the court. He became widely unpopular due to his harsh taxation and meddling with Constantinople's grain supply, as well as for his neglect of Asia Minor in the face of Turkish encroachment. This resentment led to the outbreak of two major rebellions in 1077, and the eventual abdication of Michael VII. Nikephoritzes himself was captured and tortured to death.
