Abstract: The subject of the study is the historiography of the personality of the Yakut Prince Mazary Bozekov (1633-1703). The object of the study is the biography of Mazary Bozekov, which, according to the author of the article, received a one-sided interpretation due to its ideologization in Soviet times. For the first time, the author considered the problem from the point of view of analyzing the research approaches of scientists who turned to the study of the personality of the Yakut prince. The author sought to rely on such methodological principles as careful selection of quotations to illustrate the author's approach and style to the topic under study. Another principle was to take into account the main historical trends of the era in which Mazary Bozekov lived. There were no special scientific publications devoted to the personality of the Bozekov, with the exception of some articles of a popular scientific nature. The greatest successes were achieved by S.V. Bakhrushin and S.A. Tokarev. The latter managed to introduce into scientific circulation many documents, including those on the early and late period in the life of Mazary Bozekov. The novelty of the research lies in the fact that the author has outlined promising areas for further research. He believes that modern theoretical and methodological approaches allow us to take a fresh look at the personality of Mazary Bozekov. In particular, this can be seen in the latest work of V.N. Ivanov, in which he introduced new archival materials from the arсhihe into scientific circulation and in which he proposed to consider the Yakut princes who participated in the trips as ethnic leaders. The study of the problem requires new research in terms of not only finding additional sources, but also in terms of its modern scientific understanding.
