Sultanate of Rum
The Seljuk Sultanate of Rûm was formed in 1077, when the Seljuks defeated the Byzantine Empire and started to conquer their territories in Anatolia. This occurred after the Battle of Manzikert resulted in a Byzantine defeat in 1071 and the Seljuk Muslim tribes of Anatolia conquered large parts of Anatolia and formed their own Beyliks. The Seljuks set up the Sultanate of Rûm in Anatolia in 1077. It was formed on conquered Byzantine territory. Later, the Seljuk Empire would Fall, after that the Seljuk sultanate of Rum was mostly called "Seljuk Sultanate". This sultanate propagated the Islamization of Anatolia through the influx of several Turkoman tribes into regions of Anatolia which were earlier conquered from the Christian Byzantine Empire.
