The Sultanate of Rum, or Seljuk Sultanate of Rum,[e] was a culturally Turco-Persian, Sunni Muslim state established over conquered Byzantine territories and peoples (Rum) of Anatolia by the Seljuk Turks following their entry into Anatolia after the Battle of Manzikert in 1071. The name Rum was a synonym for the medieval Roman Empire and its peoples, as it remains in modern Turkish.[13][f][g] The name is derived from the Aramaic (romī) and Parthian (frwm) names for ancient Rome, which had reached these languages via the Greek Ῥωμαῖοι (Romaioi). The Seljuk Turks used the name to refer to Anatolia.The Sultanate of Rum is considered to be the beginning of Turkish history in Anatolia.
