What is "komnenos"

Komnenos , Latinized Comnenus, plural Komnenoi or Comneni (Κομνηνοί, pronounced /komniní/), is the name of a noble family who ruled the Byzantine Empire from 1081 to 1185, and later, as the Grand Komnenoi (Μεγαλοκομνηνοί, Megalokomnenoi) founded and ruled the Empire of Trebizond (1204–1461). Through intermarriages with other noble clans, notably the Doukai, Angeloi, and Palaiologoi, the Komnenos name appears among most of the major noble houses of the late Byzantine world.
