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.
