The Sultanate of Rûm was a culturally Turco-Persian Sunni Muslim state, established over conquered Byzantine territories and peoples (Rûm) of Anatolia by the Seljuk Turks following their entry into Anatolia after the Battle of Manzikert (1071). The name Rûm was a synonym for the medieval Eastern Roman Empire and its peoples, as it remains in modern Turkish. The name is derived from the Aramaic (rhōmī) and Parthian (frwm) names for ancient Rome, via the Greek Ῥωμαῖοι (Romaioi).
