History
The district was established on August 1, 1927, when the All-Russian Central Executive Committee issued two Resolutions: "On the Establishment of Leningrad Oblast" and "On the Borders and Composition of the Okrugs of Leningrad Oblast". According to these resolutions, Murmansk Governorate was transformed into Murmansk Okrug, which was divided into six districts and included into Leningrad Oblast. The administrative center of the district was established in the selo of Kuzomen; however, it was transferred to Umba on August 15, 1931. In 1934, the Murmansk Okrug Executive Committee developed a redistricting proposal, which was approved by the Resolution of the 4th Plenary Session of the Murmansk Okrug Committee of the VKP on December 28-29, 1934 and by the Resolution of the Presidium of the Murmansk Okrug Executive Committee on February 2, 1935. On February 15, 1935, the VTsIK approved the redistricting of the okrug into seven districts, but did not specify what territories the new districts were to include. On February 26, 1935, the Presidium of the Leningrad Oblast Executive Committee worked out the details of the new district scheme and issued a resolution, which, among other things, moved the administrative center of Tersky District to the work settlement of Lesnoy. On December 26, 1962, when the Presidium of the Supreme Soviet of the RSFSR decreed to re-organize the Soviets of People's Deputies and the executive committees of the krais, oblasts, and districts into the industrial and agricultural soviets, Murmansk Oblast was not affected and kept one unified Oblast Soviet and the executive committee. Nevertheless, on February 1, 1963, the Decree by the Presidium of the Supreme Soviet of the RSFSR established the new structure of the districts of Murmansk Oblast, which classified Tersky District as rural. However, this classification only lasted for less than two years. The November 21, 1964 Decree by the Presidium of the Supreme Soviet of the RSFSR restored the unified Soviets of People's Deputies and the executive committees of the krais and oblasts where the division into the urban and rural districts was introduced in 1962, and the districts of Murmansk Oblast were re-categorized as regular districts again by the January 12, 1965 Presidium of the Supreme Soviet of the RSFSR Decree.
