Main articles: Turkic migration, Seljuk Empire, and Sultanate of Rûm
The House of Seljuk was a branch of the Kınık Oğuz Turks who resided on the periphery of the Muslim world, north of the Caspian and Aral Seas in the Yabghu Khaganate of the Oğuz confederacy[5] in the 10th century. In the 11th century, the Turkic people living in the Seljuk Empire started migrating from their ancestral homelands towards the eastern regions of Anatolia, which eventually became a new homeland of Oğuz Turkic tribes following the Battle of Manzikert in 1071.
The victory of the Seljuks gave rise to the Seljuk Sultanate of Rum, a separate branch of the larger Seljuk Empire [6] and to some Turkish principalities (beyliks), mostly situated towards the Eastern Anatolia which were vassals of or at war with Seljuk Sultanate of Rum.
