Череповецкая губерния
In June 1918, five uyezds of the Novgorod Governorate, including Kirillovsky Uyezd, were split off to form Cherepovets Governorate, with the administrative center in Cherepovets. In 1919, northwestern parts of Kirillovsky Uyezd were transferred into Kadnikovsky Uyezd of Vologda Governorate and Kargopol Uyezd of Olonets Governorate. On August 1, 1927, Cherepovets Governorate was abolished, and its area became Cherepovets Okrug of Leningrad Oblast. Simultaneously, the uyezds were abolished, and Kirillovsky District was established. On September 23, 1937, Kirillovsky District was transferred to newly established Vologda Oblast.
