The article continues a series of research works on the ethnic composition of Buryat population using a case study of the Steppe Dumas, national jurisdictions of the Russian Empire in 19^th century. Buryat self-government structures represented by Steppe Kontora and Steppe Duma functioned for more than a hundred years and contributed to the formation of stable ethnic communities of the Buryats. Although the population of many Buryat agencies was multi-tribal, communities formed within the boundaries of the Dumas, which were united by a common ethno-territorial identity. The Balagansk Steppe Duma was formed at the end of 1824 on the basis of Balagansk Steppe Kontora. It was the largest in the Irkutsk province in terms of population. At the end of the 19^th century, Balagansk Steppe Duma, as a result of the administrative reforms undertaken by the Russian Empire to unify the management system, was abolished. In its place, there were new administrative entities – Unginskaya, Nelkhayskaya, Zungaro-Bykotskoya, Ashekhabatskaya indigenous departments. The ethnic composition and settlement of the ethno-territorial group of the Balagansk Buryats is of great interest in connection with the study of Buryats ethnogenesis and the ethnic history of Baikal region. The ethnic background of the population was composed of the Bulagat tribes, since the Duma was based on the indigenous lands of the Bulagats. A significant stratum of the population of the Duma was the Ikinat tribal group. In addition to them, ethnic groups from Western Mongolia, Khubsugul region, retaining in their memory territories of their origin and identity are presented in the population of the region. The motley ethnic map of the Balagansk Steppe Duma was formed in the context of large-scale migrations of the Buryats in Transbaikalia, Mongolia and back, local migrations linking the territory of the Duma with neighboring territories of Bratsk and Nizhneudinsk fortresses. The complex ethnic composition reflects the long stage of the formation of this territorial group, which included several tribal associations of Bulagats and Ikynats. Several differently-time layers that took part not only in the ethnogenesis of the Buryats, but also in the neighboring Turkic and Mongolian peoples, which indicates the inextricable link between the history of this subregion both with Central Asia and with Southern and Northern Siberia.
