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 Cherepovets Okrug of Leningrad Oblast was established on its former territory. Simultaneously, uyezds were abolished, and Ustyuzhensky District was established, with the administrative center in the town of Ustyuzhna. On September 23, 1937, Ustyuzhensky District was transferred to newly established Vologda Oblast and remained there ever since.
