The article examines and reanalyzes the data of written sources, based on which some scholars assumed the existence of dual power in the Turkic Khaganate. First, we are talking about a hypothetical institute of the small khaganate, while the corresponding title is mentioned only in Chinese sources (kit. xiao ke-han). Secondly, it is a version of the division of power between two noble Turkic families, which grew up on the basis of a dual marriage organization, the existence of which among the Turks is also hypothetical. The specific source material does not allow us to speak about the validity of these hypotheses. Key words: Turks, khaganate, dual power, co-government, small khagan, dual organization. Dual power is considered a traditional institution for nomadic, in particular Turkic, political entities, but the nature of which, nevertheless, is seen differently by scientists [for literature, see: Doerfer, 1967, p. 161-162; Trepavlov, 1993, p.75-76, 95-96]. During the existence of the First Turkic Khaganate, the title of khagan was quite widespread. The question of the role and place of the so-called small kagans (xiao-ke-han ) and *ev kagans (< i-ke-han) in the state structure remains unclear. About the existence of the latter, the only mention in the sources refers to the period of the First Khaganate [Materials..., 1984, p. 68, 305, approx. 46; History of the Kazakh SSR, 1977, p. 331; History of Kazakhstan, 1996, p. 302; Zuev, 1998, p. 155, 159; Zuev, 2002, p. 212, 280, 289; Tasagil, 2003, p. 114], although nothing specific is reported, except that it is called "The Kazakh language". subordinate meaning in relation to the kagan (Drompp, 1991, p. 94). However, Yu. A. Zuev gave convincing arguments in favor of the fact that i-ke-han" at the dawn of Turkic history " was the title of the leader of the shire [Zuev, 1998, p. 160]. Some authors, apparently following the literal interpretation of the term, compare * ev kagan with the position of the Khazar kagan, who ... Read more
