The Sultanate of Rum (, meaning "Anatolian Seljuk State" or meaning "Turkey Seljuk State"; Saljuqiyan-i Rum), was a medieval Turko-Persian, Sunni Muslim state in Anatolia. It existed from 1077 to 1307, with capitals first at Iznik and then at Konya. However, the court of the sultanate was highly mobile, and cities like Kayseri and Sivas also temporarily functioned as capitals. At its height, the sultanate stretched across central Anatolia, from the shoreline of  Antalya and Alanya on the Mediterranean coast to the territory of Sinop on the Black Sea. In the east, the sultanate absorbed other Turkish states and reached Lake Van. Its westernmost limit was near Denizli and the gates of the Aegean basin.
