Череповецкая губерния
In June 1918, five uyezds of Novgorod Governorate, including Kirillovsky 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 Kirillovsky District was established. On September 23, 1937, Kirillovsky District was transferred to newly established Vologda Oblast.
