The article considers the process of formation of the state border protection system in the Caucasus at the end of the XIX century (on the example of the Elisavetpol border brigade). The relevance of the research lies in the insufficient study of the system of state border protection in the Caucasus by border units at the end of the XIX century. It is noted that due to joining of the Caucasian lands to the Russian Empire, the length of the state border was increased. As a result, the Russian government faced the need to ensure the security of new territories. However, to secure the new territories, it was necessary to create specialized units for the protection of the state border. The paper shows that the development of the state border protection system was carried out in difficult geographical conditions, taking into account the insufficient number of personnel of specialized border units, as well as in conditions of constant armed clashes with Persian robbers, which led to the personnel casualties. It is concluded that despite the shortage of personnel, the Ministry of Finance redistributed the personnel and managed to secure the frontier with Persia. The purpose of the study is to identify the features of the development of the protection system of the Russian Empire border in the Caucasus at the end of the XIX century.
