Olonets Governorate
After a series of administrative reforms, by the beginning of the 19th century the west of the oblast belonged to Novgorod Governorate, with the exception of Vytegorsky Uyezd which belonged to Olonets Governorate. In 1922, Olonets Governorate was abolished, and Vytegorsky Uyezd was transferred to Petrograd Governorate (later Leningrad Oblast), with the exception of three volosts, which were moved to Kargopolsky Uyezd and later ended up in Arkhangelsk Oblast.
