Череповецкая губерния
In June 1918, five uyezds of Novgorod Governorate, including Belozersky Uyezd, were split off to form Cherepovets Governorate, with the administrative center in Cherepovets. On August 1, 1927, Cherepovets Governorate was abolished, and its area became Cherepovets Okrug of Leningrad Oblast. Simultaneously, the uyezds were abolished, and Belozersky District was established. On September 23, 1937, Belozersky District was transferred to newly established Vologda Oblast.
