The article deals with the problem of the emergence and formation of prosecutor's offices in Glazovsky, Sarapulsky, Yelabuga and Malmyzhsky uyezds of Vyatka province, which later formed the territorial basis of the Udmurt Republic. The relevance of the issue is connected both with its poorly studied nature and with the continuing dubious practice of considering 1922 as the starting point in the history of the Udmurt prosecutor's office. The purpose of the article is an attempt of historical reconstruction of the organizational and legal origins and subsequent development of the prosecutor's offices in these uyezds, and also the justification of the establishment in 1874 of prosecutorial supervision bodies at the district courts in Vyatka and Sarapul as the starting point in the history under consideration. In the process of research, a wide range of general scientific and historical-legal methods were applied, based on a dialectical approach and using pre-revolutionary sources, including archival materials. The author substantiates the idea that the prosecutor's office long before the revolution of 1917 was an important element of the system of regional state-legal management, and the Soviet Prosecutor's Office of the 1920s emerged as an updated institution, restored on the basis of extensive pre-revolutionary experience and with the assistance of old specialists.
