The article is devoted to the study of the development patterns of the local government system in the Russian Federation. The submission to the State Duma of the Russian Federation of the draft Federal Law «On the general principles of the organization of local self-government in the unified system of public authority» in December 2021 means the preparation of a new stage of municipal reform and makes it relevant to study long-term changes in the institutional organization of local self-government. The purpose of the study is to analyze changes in the structure of local self-government bodies and the rules of their formation at each stage of the development of this institution, as well as to identify the main patterns of this process. The analysis of the legislative base regulating the structure and rules of formation of local self-government bodies has been carried out. The data related to the development of the local government system provided by the Ministry of Justice of the Russian Federation were analyzed. It is shown that the structure of local self-government bodies has not undergone significant changes. However, there have been changes in the ways of forming local self-government bodies, which reflect the trend towards their loss of institutional independence and integration into a single system of public power. This trend appeared at the stage of implementation of the Federal Law on Local Self-Government in 2003 and was consolidated in the new Draft law on Local self-government submitted to the State Duma of the Russian Federation in 2021. It is concluded that there is a tendency to increase the dependence on federal and regional legislators of local self-government bodies. For the institute of heads of municipalities, the loss of institutional independence was clearly manifested by the introduction of the procedure for electing heads by competition, displacing both election at municipal elections and election from the Council of Deputies. The formation of representative bodies, having passed the stage of delegating deputies to higher levels, returns to the model of direct elections. However, this happens in the context of the rejection of a two-tier system of local self-government.
