Today we know that the heroic epos "Edigey" remained among the Turkic people living in the south from Turkmenistan and Uzbekistan to Siberia, as well as in foreign countries: Turkey and Romania. "Edigey" epos has more than 40 versions, some of which consist of fifteen or sixteen thousand lines. Therefore, a narrow study is not enough for in-depth analysis of the nature of the epic. The archaic and contemporary versions of the epic, the diversity of its national versions contribute significantly to the study of the dynamics of the epic tradition of literature of Turkic-speaking people. The general laws of these phenomena in science were determined through a comparative analysis. However, a similar study of national versions of the epic, in our opinion, is currently being implemented or not implemented not so often. The development of this topic also meets the objectives of the state program "Cultural Heritage". "Edigey" epic allows us to consider the main literary traditions of the Turks, which connect real historical events and personalities, with fictitious hyperbolized scenes. It reveals the attitude of Turkic people to described historical realities, shows the impact of these events on the worldview of the Turks.
