Leningrad Oblast was established on August 1, 1927, by the resolutions of the All-Russian Central Executive Committee "On the Establishment of Leningrad Oblast" and "On the Borders and Composition of the Okrugs of Leningrad Oblast" by merging Cherepovets, Leningrad, Murmansk, Novgorod, and Pskov Governorates. The territory of the oblast corresponded to the modern territories of the present-day Leningrad Oblast (with the exception of the Karelian Isthmus and the territories along the border with Estonia), Novgorod Oblast, Pskov Oblast, parts of Vologda Oblast, most of Murmansk Oblast, and the federal city of Saint Petersburg. The total area of the oblast was ; more than four times larger than the modern entity. Administratively, the oblast was divided into nine okrugs (Borovichi, Cherepovets, Leningrad, Lodeynoye Pole, Luga, Murmansk, Novgorod, Pskov, and Velikiye Luki), each of which was in turn subdivided into districts.
