Ida-Viru County in the context of "Counties of Estonia"

Leningrad Oblast (Russian: Ленинградская область, romanized: Leningradskaya oblastʹ, IPA: [lʲɪnʲɪnˈgratskəjə ˈobləsʲtʲ]; Veps: Leningradan agj; Finnish: Leningradin alue) is a federal subject of Russia (an oblast). The oblast has an area of 84,500 square kilometres (32,600 sq mi) and a population of 2,000,997 (2021 Census); up from 1,716,868 recorded in the 2010 Census. Leningrad Oblast is highly industrialized. Its administrative center and largest city is Gatchina.

The oblast was established on 1 August 1927, although it was not until 1946 that the oblast's borders had been mostly settled in their present position. The oblast was named after the city of Leningrad. In 1991, the city restored its original name, Saint Petersburg, but the oblast retains the name of Leningrad. It overlaps the historical region of Ingria, and is bordered by Finland (Kymenlaakso and South Karelia) in the northwest and Estonia (Ida-Viru County) in the west, as well as five federal subjects of Russia: the Republic of Karelia in the northeast, Vologda Oblast in the east, Novgorod Oblast in the south, Pskov Oblast in the southwest, and the federal city of Saint Petersburg in the west.

Virumaa or Viru (Latin: Vironia; Low German: Wierland; Old Norse: Virland) is an historical region in northeastern Estonia and a medieval independent Estonian county (maakond). In most part, the historical Virumaa region overlaps with modern Lääne-Viru ("West Viru") and Ida-Viru ("East Viru") counties.

Medieval people of Virumaa, the Vironians, built many strongholds, like Tarwanpe (modern Rakvere) and Agelinde (now Punamägi Hill in Äntu village). Vironians were divided into five clans (kilikunda), Maum (in Estonian "Mahu"), Laemund (Lemmu) also known as Pudiviru, Askele, Revele (Rebala), Alentagh (Alutaguse). Like other Estonian tribes, Vironians remained predominantly pagan before Northern Crusades in the 13th century.

Saint Petersburg Governorate was a province (guberniya) of the Russian Empire, with its capital in Saint Petersburg. The governorate was composed of 44,613 square kilometres (17,225 sq mi) of area and 2,112,033 inhabitants. It was bordered by Estonian and Livonian Governorates to the west, Pskov Governorate to the south, Novgorod Governorate to the east, Olonets Governorate to the northeast, and Vyborg Governorate of the Grand Duchy of Finland to the north. The governorate covered most of the areas of modern Leningrad Oblast and Ida-Viru, Jõgeva, Tartu, Põlva, and Võru counties of Estonia.
