Олонецкая губерния
The east and south of the current area of the oblast was transferred in 1727 to Moscow and Novgorod Governorates. After a sequence of administrative reforms, the northeastern part of the oblast ended up in 1801 in Olonets Governorate. In June 1918, five uyezds of Novgorod Governorate, including Tikhvinsky Uyezd, were split off to form Cherepovets Governorate, with the administrative center in Cherepovets. In 1922, Olonets Governorate was abolished, and Lodeynopolsky Uyezd (which contained all areas later transferred to Leningrad Oblast) was transferred to Petrograd Governorate. Thus, by 1927 the current area of the oblast was split between three governorates — Leningrad, Novgorod, and Cherepovets.
