The main object of research of Lev Nikolayevich Gumilev was history of the nomadic people of the Great steppe. Deeply studying history and culture of the nomadic people, L. Gumilyov had huge respect and sympathy for the people of Eurasia. For this reason his scientific work "Ancient Turkic Peoples" begins with words: "I devote this book to our brothers — the Turkic people of the Soviet Union". Marking huge value ancient Turk in the history of mankind, the scientist with a big regret states that "… the history of these people is still not written. It was explained in passing and in abbreviated form…"
In this regard, L. Gumilyov’s role and scientific contribution in study of socio-political and ethnic history, tradition of statehood and the power, culture of the Turkic people is huge. It is important for us that one of receivers of Turkic heritage is also the Kazakh people.
