Abstract
The steppes of the Syrdaria are the natural boundary between the nomadic peoples of Central Asia and the peoples involved in sedentary agriculture. Due to the large number of ancient settlements and settlements on the Syrdaria River and the dense population of the settlers in this area of Syrdaria is a natural boundary between nomadic and sedentary peoples of Central Asia. The article begins with the confluence of the Naryn and Karadaria rivers in the Fergana basin and ends with several tributaries: the Incardarya and Janadarya rivers, as well as the main tributary of the Syr-Darya, draining into the Aral Sea. Medieval cities and toponyms such as Sutkent and Bairkum were also studied and scientifically analysed. To this end, we have tried to systematically explain these cities by studying historical written and archaeological data. In the article we aimed to draw public attention to archaeological research, popularization and inclusion of the abovementioned cities in the list of tourist attractions. In addition, we decided to study the abovementioned citizens and introduce them into scientific circulation.
