Oguz Lands
In the first half of the 10th century, Oguz people were observed in the steppe lands of Seyhun and within the environs of the cities of Karacuk (Farab) and Sayram (isticab). According to the Islamic geographers and (Al-Balhi, İstahri, İbn Havkal) and the work titled as Hududü'l-Alem, the region of Oguz people had expanded within the lands extending from the Caspian Sea in the west (therefore, the peninsula located in the east of this sea was named as Mankışlak in Turkish), the city of Gürgenç in the south and the town of Cit in the south-west of this city, the town of Baratekin (in the south of the Lake Aral), and the south of Bokhara in Transoxania towards the city of Savran located in the skirts of Karacuk Mountains. The semidesert that extended from the Karacuk Mountains towards the Caspian Sea was called as "Oguz Steppe Lands" (Mafazü'l-Guziya).
