Cherepovets Governorate
In June 1918, five uyezds of Novgorod Governorate, including Ustyuzhensky Uyezd, were split off to form Cherepovets Governorate, with the administrative center in Cherepovets. On August 1, 1927, Cherepovets Governorate was abolished and its territory became Cherepovets Okrug of Leningrad Oblast. At the same time, uyezds were abolished and Ustyuzhensky District was established, with the administrative center in Ustyuzhna. On September 23, 1937, Ustyuzhensky District was transferred to newly established Vologda Oblast and remained there ever since.
