In the context of Byzantine history, the period from about 1081 to about 1185 is often known as the Komnenian or Comnenian period, after the Komnenos dynasty. Together, the five Komnenian emperors (Alexios I, John II, Manuel I, Alexios II and Andronikos I) ruled for 104 years, presiding over a sustained, though ultimately incomplete, restoration of the military, territorial, economic and political position of the Byzantine Empire.
