Северный край
On July 15, 1929, several governorates, including Vologda Governorate, were merged into Northern Krai, and the uyezds were abolished. Instead, Chyobsarsky District with the administrative center in the railway station of Chyobsara (which is now an urban-type settlement) was established as a part of Vologda Okrug. In 1936, Northern Krai was transformed into Northern Oblast. In 1937, Northern Oblast was split into Arkhangelsk Oblast and Vologda Oblast. Chyobsarsky District remained in Vologda Oblast.
