Northern Krai
In 1929, Northern Dvina Governorate was merged into Northern Krai. The krai consisted of five okrugs, one of which, Northern Dvina Okrug, had its administrative center in Veliky Ustyug. In July 1930, the okrugs were abolished, and the districts were directly subordinated to Northern Krai. In 1936, Northern Krai was transformed into Northern Oblast, and in 1937, Northern Oblast was split into Arkhangelsk Oblast and Vologda Oblast. Veliky Ustyug remained in Vologda Oblast ever since.
