Russian language East Slavic language

Russian is an East Slavic language, which is official in the Russian Federation, Belarus, Kazakhstan and Kyrgyzstan, as well as being widely used throughout Eastern Europe, the Baltic states, the Caucasus and Central Asia. It was the de facto language of the Soviet Union until its dissolution on 25 December 1991. Although, nowadays, nearly three decades after the breakup of the Soviet Union, Russian is used in official capacity or in public life in all the post-Soviet nation-states, as well as in Israel and Mongolia, the rise of state-specific varieties of this language tends to be strongly denied in Russia, in line with the Russian World ideology.

Finnish language language arising and mostly spoken in Finland, of the Finnic family

Finnish is a Finnic language spoken by the majority of the population in Finland and by ethnic Finns outside Finland. Finnish is one of the two official languages of Finland ; Finnish is also an official minority language in Sweden. In Sweden, both Standard Finnish and Meänkieli, a Finnish dialect, are spoken. The Kven language, a dialect of Finnish, is spoken in Northern Norway by a minority group of Finnish descent.

Vyborg Bay

Vyborg Bay is a deep inlet running northeastward near the eastern end of Gulf of Finland in the Baltic Sea. The city of Vyborg is located near the head of the gulf.

The fort is located about 12 kilometres south of Vyborg in the islands of Vysotsky and Maly Vysotsky. Trångsund Fortress received its present form after the Crimean War in the 1860s. The structures dating back to the early 18th Century are no longer visible. In the early 1900s, the fort was intended to be a part of the Peter the Great's Naval Fortress but it was disarmed by the World War I. [1] During the 1918 Finnish Civil War the Trångsund Fortress was occupied by the local Women's Red Guard. [2]

Crimean War 1850s military conflict

The Crimean War was a military conflict fought from October 1853 to February 1856 in which the Russian Empire lost to an alliance of the Ottoman Empire, France, Britain and Sardinia. The immediate cause involved the rights of Christian minorities in the Holy Land, which was a part of the Ottoman Empire. The French promoted the rights of Roman Catholics, while Russia promoted those of the Eastern Orthodox Church. The longer-term causes involved the decline of the Ottoman Empire and the unwillingness of Britain and France to allow Russia to gain territory and power at Ottoman expense. It has widely been noted that the causes, in one case involving an argument over a key, have never revealed a "greater confusion of purpose", yet led to a war noted for its "notoriously incompetent international butchery".

Gulf of Finland arm of the Baltic Sea

The Gulf of Finland is the easternmost arm of the Baltic Sea. It extends between Finland and Estonia all the way to Saint Petersburg in Russia, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the Gulf of Finland belong to Russia, and some of Russia's most important oil harbours are located farthest in, near Saint Petersburg. As the seaway to Saint Petersburg, the Gulf of Finland has been and continues to be of considerable strategic importance to Russia. Some of the environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf.

The Russo–Swedish War of 1741–1743, known as the Hats' Russian War in Sweden and the War of the Hats in Finland, which resulted in the Lesser Wrath, or the occupation of Finland, was instigated by the Hats, a Swedish political party that aspired to regain the territories lost to Russia during the Great Northern War, and by French diplomacy, which sought to divert Russia's attention from supporting its long-standing ally, the Habsburg monarchy, in the War of the Austrian Succession.

Nyenschantz was built in 1611 to establish Swedish rule in Ingria, which had been annexed from the Tsardom of Russia during the Time of Troubles. The town of Nyen, which formed around Nyenschantz, became a wealthy trading center and a capital of Swedish Ingria during the 17th century. In 1702, Nyenschantz and Nyen were conquered by Russia during the Great Northern War, and the new Russian capital of Saint Petersburg was established by Peter the Great in their place the following year.

Svartholm fortress

The Svartholm fortress was built between 1749 and 1764 outside Loviisa in Southern Finland by Augustin Ehrensvärd.

Krepost Sveaborg

The Krepost Sveaborg was an Imperial Russian system of land and coastal fortifications constructed around Helsinki during the First World War. The purpose of the fortress was to provide a secure naval base for the Russian Baltic fleet and to protect Helsinki and block routes to Saint Petersburg from a possible German invasion. Krepost Sveaborg was part of Peter the Great's Naval Fortress, a coastal fortification system protecting access to Saint Petersburg by sea. The central part of Krepost Sveaborg was the old fortress of Suomenlinna where the fortress headquarters were located. Due to technological advances in artillery the old fortress was no longer capable of providing a sufficient protection, and a new main defensive line was built well beyond the old fortress boundaries. New coastal artillery guns built on outlying islands protected Krepost Sveaborg from the sea, while fortified lines constructed around Helsinki were intended to stop any attacks on land. The primary coastal guns were 10 in (254 mm) model 1891 guns and 6 in (152 mm) model 1892 Canet guns. Older 11 in (279 mm) model 1877 guns were also used. In summer 1917 the fortress had two hundred coastal or anti-landing guns, of which 24 were 10-inch guns in six batteries, 16 were 6-inch Canet guns in four batteries and twelve were 11-inch guns in three batteries. The artillery used in land fortifications included older coastal guns, old fixed carriage guns and newer light field guns. In March 1917, Krepost Sveaborg had a total of 463 guns, although many of them were obsolescent. Krepost Sveaborg was still partly incomplete in 1917 when the February Revolution halted most of the construction work. Some further construction work was carried out during the remaining year, but all work halted during the October Revolution. Following the Finnish Declaration of Independence, parts of the land fortifications were used in the Finnish Civil War. The coastal fortifications were later taken over by Finland to protect Helsinki, while the land fortifications were mostly abandoned and disarmed.

During the First World War fourteen guns were used as a coastal guns on Gulf of Finland in the Peter the Great's Naval Fortress and were taken over by Finland after Finland's Declaration of Independence in 1917. The guns were used by Finland in the Second World War. Russian model year 1877 refers to rifling system, not gun adoption.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
