The Seljuk Sultanate of Rum was the
Seljuk Turkish sultanate that ruled in direct lineage from 1077 to 1307 in
Anatolia, with capitals, successively, in
İznik (
Nicaea) for a brief period in its beginnings, and then in
Konya in
Central Anatolia. Its sultans having pursued their reigns in a high degree of mobility, cities like Kayseri and Sivas also bore aspects of
capitals at times. At its height, it stretched across central
Turkey from
Antalya-Alanya shoreline on the
Mediterranean coast to
Sinop and the neighboring region on the
Black Sea coast. To the east, the sultanate reached the region of
Lake Van, after having absorbed other Turkish states, and its westernmost limit was near
Denizli at the gates of the
Aegean basin proper, where their rule was succeeded by smaller
Beyliks.
