The study of the ancient tribes that inhabited the Eurasian steppes is considered one of the basic steps toward elucidating our deep ethnic history. However, a long history introduces various changes to the original appearance of any ethnic group. Such changes are often influenced by political and cultural transformations in society. Consequently, the name of some ancient tribes fades from history and disappears altogether, some are known under new names, and only some tribes can retain their ancient names.The most famous of these ancient tribes is the Turkic tribe, known for many centuries in historical records as “Tokuz-Tatars”. They are considered one of the most important tribes in studying the evolution of the ethnic history of the Kazakh people. The name "Tokuz-Oguz" first appears in the text of an ancient Turkic monument, from which important information was obtained about an event that took place in the history of the Turkic Khaganate in 715. Since then, their name was long preserved and appeared in the pages of literature until the 11th century. Soon the names of separate political-ethnic associations began to appear instead of this common name “Tokuz-Tatars”. However, their political activity ceased completely in the Mongolian era.
