Архангелогородская губерния
In the course of the administrative reform carried out in 1708 by Peter the Great, the area was included into Archangelgorod Governorate. In 1780, Arkhangelogorod Governorate was abolished and transformed into Vologda Viceroyalty, and in 1796 the latter was split into Arkhangelsk and Vologda Governorates. What is now Sokolsky District was then a part of Kadnikovsky Uyezd of Vologda Governorate. Kadnikov was chartered in 1780.
