In the
Viking era (late
Iron Age), from the 750s onwards,
Ladoga served as a bridgehead on the
Varangian trade route to Eastern Europe. A mixed slavic-varangian
aristocracy developed that would ultimately rule over
Novgorod and
Kievan Rus'. In the 860s, the warring
Finnic and
Slavic tribes rebelled under
Vadim the Bold, but later asked the Varangians under
Rurik to return and to put an end to the recurring conflicts between them. The Swedes referred to the ancient
Novgorodian land of
Vod people as
Ingermanland, Latinized to
Ingria. The origin of the name is uncertain, but there are several possible explanations. One explanation is that the name comes from the
River Inger, a southern tributary of the
Neva River. Another explanation is based on the Norwegian
Eymund's saga, which tells the story of the Swedish princess
Ingegerd Olofsdotter, who married
Yaroslav the Wise, Grand Prince of Novgorod and Kiev in 1019. According to the saga, she received Ladoga and the surrounding lands as a wedding gift from Yaroslav, and the region came to be known as ''Ingegerd's land
, or Ingermanland''. The lands were administered by Swedish
jarls, such as
Ragnvald Ulfsson, under the sovereignty of the
Novgorod Republic. In the 12th century, Western Ingria was absorbed by the Novgorod Republic. There followed centuries of
frequent wars, chiefly between Novgorod and Sweden, and occasionally involving
Denmark and
Teutonic Knights as well. The Teutonic Knights established a stronghold in the town of
Narva, followed by the Russian castle
Ivangorod on the opposite side of the Narva River in 1492. With the consolidation of the
Kievan Rus and the expansion of the
Republic of Novgorod north, the indigenous Ingrians became
Eastern Orthodox. Ingria became a province of Sweden in the
Treaty of Stolbovo in 1617 that ended the
Ingrian War, fought between Sweden and Russia. After the Swedish conquest of the area in 1617 the
Ingrian Finns, descendants of 17th-century
Lutheran emigrants from present-day
Finland, became the majority in Ingria. In 1710, following a Russian conquest, Ingria was designated as the Province of St. Petersburg. In the
Treaty of Nystad in 1721, Sweden formally ceded Ingria to Russia. In 1927 the Soviet authorities designated the area as Leningrad Province.
Deportations of the Ingrian Finns started in late 1920s, and
Russification was nearly complete by the 1940s. In the modern era, Ingria forms the northwestern anchor of Russia—its "window" on the
Baltic Sea—with
Saint Petersburg as its centre. ==Swedish Ingria==
