# Kaliningrad Oblast

Kaliningrad Oblast is the westernmost part of Russia. It is a small flat province separated from the rest of the country by the Baltic Sea and two European Union and NATO members: Poland to the south and Lithuania to the north and east.
Half of the oblast's one million people live in the city of Kaliningrad, formerly known as Königsberg, which is the provincial capital. Due to sanctions the economy is dependent on subsidies and the military. The port city of Baltiysk is Russia's only port on the Baltic Sea that remains ice-free in winter.
Various peoples, including Lithuanians, Germans and Poles, lived on the land which is now Kaliningrad. In the 18th century it was East Prussia, which became part of Germany. But after defeat in World War II in the mid-20th century the Germans fled or were expelled, and the victorious Soviet Union repopulated the territory, mostly with Russians.

## History

The territory of what is now the Kaliningrad Oblast used to be inhabited by the Old Prussians and other Western Balts, prior to the Teutonic conquest in the early Late Middle Ages. Afterwards, it was settled by Germans (especially the western part), Lithuanians (especially Lithuania Minor) and Poles (especially Königsberg, Polish: Królewiec, and the current southern border strip). The Old Prussians became extinct due to Germanisation in the first half of the 18th century. The Lithuanian-inhabited areas of the Teutonic State were known as Lithuania Minor, which encompassed all of modern Kaliningrad Oblast until the 18th century.

### Late Middle Ages

In the 13th century, the Teutonic Order conquered the region and established the State of the Teutonic Order, a theocracy. In 1255, on the foundations of a destroyed Sambian settlement known as Tvanksta, the Teutonic Order founded the city of Königsberg (modern Kaliningrad), naming it in honour of Ottokar II of Bohemia.
The Northern Crusades, including the Lithuanian Crusade, were partly motivated by colonization. The German colonist peasants, craftsmen, and merchants were predominantly concentrated in the southern part of the Teutonic State and did not move into Nadruvia and Skalvia due to the Lithuanian military threat.
In 1454, following a request by the anti-Teutonic Prussian Confederation, the territory was incorporated to the Kingdom of Poland by King Casimir IV Jagiellon, an event that sparked the Thirteen Years' War (1454–1466). After Poland's victory in the war with the Second Peace of Thorn, the State of the Teutonic Order became a vassal of Poland, also considered an integral part of "one and indivisible" Kingdom of Poland. During this war, the capital of the Teutonic state was moved from Marienburg (now Malbork) to Königsberg in 1457. When the rulers of Prussia were vassals of the King of Poland from 1466 to 1660, there were few German colonists.

### Early modern period

After the Teutonic Order lost the war of 1519–1521 with Poland, the Teutonic Order remained a vassal of the Kingdom of Poland. In 1525, Grand Master Albert of Brandenburg secularized the Teutonic Order's Prussian branch and established himself as ruler of the Duchy of Prussia, the first Protestant state in Europe. Königsberg was the residence of the Duke of Prussia from 1525 until 1701, and was the Duchy of Prussia's capital until 1660, when the capital moved to Berlin.
Polish and Lithuanian culture blossomed in Königsberg, with the city being the place of publication of the first Polish- and Lithuanian-language cathechisms (by Jan Seklucjan and Martynas Mažvydas), the first Polish translation of the New Testament, Grammatica Litvanica, the first Lithuanian grammar book, and the Albertina University being the second oldest university of the Polish–Lithuanian Commonwealth, after receiving a royal privilege from King Sigismund II Augustus in 1560. Polish printing continued for centuries with the last Polish publication in 1931.
In 1577, the Duke of Prussia forbade serfs—who were mostly Old Prussians, Lithuanians, and Masurians—to leave the land that was the property of the German knights who became proprietary nobles.
In 1618, the Duchy merged with the Margraviate of Brandenburg to form Brandenburg-Prussia, remaining under Polish suzerainty until 1660. There was strong opposition to the separation of the region from Poland, especially in Königsberg. A confederation was formed in the city to maintain Poland's sovereignty over the city and region. The Brandenburg Elector and his army, however, entered the city and abducted and imprisoned the leader of the city's anti-Elector opposition Hieronymus Roth. In 1663, the city burghers, forced by Elector Frederick William, swore an oath of allegiance to him, however, in the same ceremony they still also pledged allegiance to Poland.
In 1724, King Frederick William I of Prussia prohibited Poles, Samogitians and Jews from settling in Lithuania Minor, and initiated German colonization to change the region's ethnic composition. In 1734–1736, Königsberg was the place of stay of Polish King Stanisław Leszczyński during the War of the Polish Succession. In 1756 Russia decided to go to war with the Kingdom of Prussia and annex the territory, which was then to be offered to Poland as part of a territorial exchange desired by Russia. The territory was occupied and annexed by Russia in 1758 during the Seven Years' War before being returned to Prussia in 1762 when Russia switched sides in the war. It was then reorganized into the province of East Prussia within the Kingdom of Prussia in 1773.
The current oblast also contains the now abandoned village of Narmeln (Polish: Polski), which was not part of Ducal Prussia, but of the Pomeranian Voivodeship of the Kingdom of Poland until its annexation by the Kingdom of Prussia the Second Partition of Poland in 1793, and is thus part of the historic region of Pomerania.

### 19th century
#### Napoleonic invasion and occupation

After the defeats of Jena–Auerstedt, the Kingdom of Prussia was invaded and Berlin was occupied by the French. The Court of Prussia fled to Königsberg, asking for Russian help. Russia intervened, leading to the bloody Battle of Eylau and Battle of Friedland in 1807. Following a French victory in the latter, both sides signed the Treaties of Tilsit.

#### Historical ethnic and religious structure

In 1817, East Prussia had 796,204 Protestants, 120,123 Catholics, 2,389 Jews, and 864 Mennonites.
In 1824, shortly before its merger with West Prussia, the population of East Prussia was 1,080,000 people. According to Karl Andree, Germans were slightly more than half of the people, while 280,000 (~26%) were ethnically Polish and 200,000 (~19%) were ethnically Lithuanian. As of 1819, there were also 20,000-strong ethnic Curonian and Latvian minorities as well as 2,400 Jews, according to Georg Hassel. Similar numbers are given by August von Haxthausen in his 1839 book, with a breakdown by county. However, the majority of East Prussian Polish and Lithuanian inhabitants were Lutherans, not Catholics like their ethnic kinsmen across the border in the Russian Empire. Only in southern Warmia did Catholic Poles—so called Warmians (not to be confused with predominantly Protestant Masurians)—comprise the majority of the population, numbering 26,067 people (~81%) in county Allenstein (Polish: Olsztyn) in 1837.

#### German culture and Germanization

In the 19th century, East Prussia was commonly viewed by German commentators as culturally backwards and a part of the "German mission in the East" rather than a core German territory. Pan-Germanist politician Ernst Hasse criticised the lack of folk identity and imagined community: "It is the case that there is almost no common folk identity [Landsmannschaften] among the Poseners and Prussians at all. [...] Who can recognise a Posener or Prussian by dialect and character? Distinct features hardly exist." While the north of East Prussia was overwhelmingly German, the south was majority Slavic and mostly composed of Poles and Masurians. There was also a slight Lithuanian majority in the north-eastern area of East Prussia, Lithuania Minor. Regional and local identities were particularly strong in East Prussia - local Polish population often identified with Masuria rather than Poland, and Prussian Lithuanians also did not actively identify themselves with the Lithuanian nation. Moreover, confessional identity often prevailed over the national one - German authorities were concerned about the "Catholic-Polish axis"; German Catholics were alienated from the German nation because of the Kulturkampf legislation, and tended to support the Polish national movement. An East German newspaper Thorner Zeitung reported in 1871 that "not only Polish Catholics, but also a great number of German Catholics, are willing to vote for a Polish party candidate".
By the end of the 19th century, East Prussia had a significant Polish minority, and German nationalist circles warned of the prospect of Polonization of East Prussia. The perceived weakness of Germanness of East Prussia was also reinforced by the Ostflucht, as East Prussia suffered from both underindustrialisation and rural overpopulation. After 1876, farm prices in East Prussia fell by 20 percent, which encouraged local landowners to hire foreign workers from Congress Poland, incidentally strengthening the Polish element in the region. The increased Slavic immigration to the region generated by the requirement of the Junkers for cheap labour and better economic conditions in West Germany caused many German inhabitants to leave the region. Most Germans moved to work in the industrial heartland of western Germany, while others migrated abroad. Poles and Lithuanians of East Prussia also had much higher birth-rate and natural increase rates than the Germans, and rarely emigrated. Discussing the situation in East Prussia, Polish geographer Stanisław Srokowski remarked:
   The Poles who live in the southern and western parts of East Prussia and the Lithuanians of the north-west have succeeded better than the Germans in reconciling their mode of life with their earnings. This has, of course, led to a lower standard of life, but it has enabled them to adapt themselves to actual conditions and even to prosper where the Germans fail. Moreover, both these national minorities in East Prussia are bound to the soil by centuries of tradition: they are not comparative new-comers like the majority of the Germans there. For these reasons, the Poles and Lithuanians in that province hardly ever emigrate from the land of their birth, especially as the emigration in question is not so attractive for them as for the Germans: proceeding to central or western Germany, the former would really be going to a foreign country, amongst people not speaking their language and having other customs than theirs.
The Memel Territory (Klaipėda region), formerly part of northeastern East Prussia as well as Prussian Lithuania, was annexed by Lithuania in 1923. In 1938, Nazi Germany radically renamed about a third of the place names of this area, replacing Old Prussian and Lithuanian names with newly invented German names.

### 20th century
#### World War I and II

In September 1914, after hostilities began between the German Empire on the one hand and France and Russia on the other, the Imperial German Army was about to seize Paris, and the French urged Russia to attack East Prussia. Nicholas II launched a major attack, resulting in a Russian victory in the Battle of Gumbinnen. The Russian army arrived at the outskirts of the city of Königsberg but did not take it and settled at Insterburg. This Russian victory and East Prussia's occupation by Russia saved Paris by forcing the Germans to send many troops to their East provinces. Later, Hindenburg and Ludendorff pushed Russia back at the battle of Tannenberg, thereby liberating East Prussia from Russian troops. Yet Russian troops remained in the easternmost part of the region until early 1915.
During World War II, the Hohenbruch concentration camp [de] was operated at modern Gromovo mostly interring Polish prisoners, as well as several subcamps of the Stutthof concentration camp, the Oflag 52, Oflag 60 and Dulag Luft prisoner-of-war camps, and a camp interring Romani people in Königsberg (see Romani Holocaust).
On 29 August 1944, Soviet troops reached the border of East Prussia. By January 1945, they had taken all of East Prussia except for the area around Königsberg. Many inhabitants fled west at this time. During the last days of the war, over two million people fled, anticipating imminent Red Army conquest, and were evacuated by sea.

#### Soviet annexation

Initially, at the end of World War II in 1945, the current southern border strip passed under Polish control with Polish administration organized in the towns of Gierdawy and Iławka, however, the area was eventually annexed by the Soviet Union and included within the Kaliningrad Oblast.
Under the Potsdam Agreement of 1 August 1945, Königsberg became part of the Soviet Union pending the final determination of territorial borders at an anticipated peace settlement. This final determination eventually took place on 12 September 1990 when the Treaty on the Final Settlement with Respect to Germany was signed. The excerpt from the initial agreement pertaining to the partition of East Prussia, including the area surrounding Königsberg, is as follows (note that Königsberg is spelt "Koenigsberg" in the original document):
   VI. CITY OF KOENIGSBERG AND THE ADJACENT AREA The Conference examined a proposal by the Soviet Government that pending the final determination of territorial questions at the peace settlement, the section of the western frontier of the Union of Soviet Socialist Republics which is adjacent to the Baltic Sea should pass from a point on the eastern shore of the Bay of Danzig to the east, north of Braunsberg – Goldep, to the meeting point of the frontiers of Lithuania, the Polish Republic and East Prussia.
   The Conference has agreed in principle to the proposal of the Soviet Government concerning the ultimate transfer to the Soviet Union of the city of Koenigsberg and the area adjacent to it as described above, subject to expert examination of the actual frontier.
   U.S. president Harry Truman and British prime minister Clement Attlee supported the proposal of the Conference at the forthcoming peace settlement.
In 1946, Königsberg was added as a semi-exclave to the Russian SFSR and renamed Kaliningrad, after the Chairman of the Presidium of the Supreme Soviet of the USSR Mikhail Kalinin. Kalinin was unrelated to the city, and there were already cities named in honour of Kalinin in the Soviet Union, namely Kalinin (now Tver) and Kaliningrad (now Korolev, Moscow Oblast). The German language was replaced with the Russian language, and the remaining German population was expelled between 1947 and 1948. The territory was then re-populated with Soviet citizens, mostly ethnic Russians but to a lesser extent also Ukrainians and Belarusians.
Some historians speculate that it may have originally been offered to the Lithuanian SSR because the resolution from the conference specifies that Kaliningrad's border would be at the (pre-war) Lithuanian frontier. According to some historians, Joseph Stalin created it as an oblast separate from the Lithuanian SSR because it further separated the Baltic states from the West. Others think that the reason was that the region was far too strategic for the USSR to leave it in the hands of another SSR other than the Russian one. In the 1950s, Nikita Khrushchev offered the entire Kaliningrad Oblast to the Lithuanian SSR but Antanas Sniečkus refused to accept the territory because it would add at least a million ethnic Russians to Lithuania proper.
In the Soviet era, the city was completely closed and, with the exception of rare visits of friendship from neighboring Poland, it was practically not visited by foreigners. In 1950, there were 1,165,000 inhabitants, which was only half the number of the pre-war population. The old city was not restored, and the ruins of the Königsberg Castle were demolished in the late 1960s, on Leonid Brezhnev's personal orders, despite the protests of architects, historians and residents of the city.
The reconstruction of the oblast, threatened by hunger in the immediate post-war years, was carried out through an ambitious policy of oceanic fishing with the creation of one of the main fishing harbours of the USSR in Kaliningrad city. Fishing not only fed the regional economy but also was a basis for social and scientific development, in particular oceanography. From 1953 to 1962, a monument to Stalin stood on Victory Square. In 1973, the town hall was turned into the House of Soviets. In 1975, the trolleybus was launched again. In 1980, a concert hall was opened in the building of the former Lutheran Church of the Holy Family. In 1986, the Kreuzkirche building was transferred to the Russian Orthodox Church.
In 1957, an agreement was signed and later came into force which delimited the border between the Polish People's Republic (a Soviet satellite state at the time) and the Soviet Union.
In 2010, the German magazine Der Spiegel published a report claiming that Kaliningrad had been offered to Germany in 1990 (against payment). The offer was not seriously considered by the West German government which, at the time, saw reunification with East Germany as a higher priority. However, this story was later denied by Mikhail Gorbachev.

### Recent history

The independence of Lithuania in 1990 and full dissolution of the Soviet Union in 1991 isolated Kaliningrad from the rest of Russia, having previously been joined by other Soviet republics. This isolation became more severe when both Poland and Lithuania joined NATO and the European Union and imposed strict border controls on Kaliningrad Oblast. All military and civilian land links between the region and the rest of Russia now must pass through members of NATO and the EU. Thus far, the EU has rejected Russian proposals for visa-free travel between Kaliningrad and the rest of Russia. Travel arrangements based on the Facilitated Transit Document (FTD) and Facilitated Rail Transit Document (FRTD) have been made. Kaliningrad Oblast's geographic isolation has badly affected its economic situation. Concurrent significant reduction in the size of the Russian military garrison has hurt as well, since previously the military was a major local employer.
Some of the region's cultural heritage, most notably the Königsberg Cathedral, was restored in the 1990s, as citizens started to examine previously ignored German past.
On 12 January 1996, Kaliningrad Oblast and Sverdlovsk Oblast became the first oblasts of Russia to sign a power-sharing treaty with the federal government, granting them autonomy. However, this agreement was abolished on 31 May 2002.
After 1991, some ethnic Germans emigrated to the area, such as Volga Germans from other parts of Russia and Kazakhstan. These Germans are overwhelmingly Russian-speaking and as such were rejected for resettlement within Germany under Germany's new rules. A similar migration by Poles from the lands of the former Soviet Union to the Kaliningrad Oblast occurred at this time as well. The situation has begun to change, albeit slowly. Germany, Lithuania, and Poland have renewed contact with Kaliningrad Oblast, through town twinning and other projects. This has helped to promote interest in the history and culture of the East Prussian and Lietuvininkai communities.
In July 2007, Russian First Deputy Prime Minister Sergei Ivanov declared that if US-controlled missile defense systems were deployed in Poland, then nuclear weapons might be deployed in Kaliningrad. On 5 November 2008, Russian president Dmitry Medvedev said that installing missiles in Kaliningrad was almost a certainty. These plans were suspended in January 2009, but implemented in October 2016. In 2011, a long-range Voronezh radar was commissioned to monitor missile launches within about 6,000 km (3,700 mi). The radar is situated in the settlement of Pionersky in Kaliningrad Oblast.
A few months after the 2022 Russian invasion of Ukraine, Lithuania started implementing EU sanctions, which blocked about 50% of the goods being imported into Kaliningrad by rail. Food, medicine, and passenger travel were exempted. Russia protested against the sanctions and announced it would increase shipments by sea. In May 2023, Poland officially adopted a new name for the Kaliningrad region, changing it from "Obwód Kaliningradzki" to "Obwód Królewiecki", Królewiec being the historical Polish name for the city of Kaliningrad. The reason given for the change is that Mikhail Kalinin, a member of the Soviet Politburo, was among those responsible for the Katyn massacre, having co-signed the order to murder thousands of Polish prisoners of war.

## Geography

Kaliningrad is the only Russian Baltic Sea port that is ice-free all year and hence plays an important role in the maintenance of the country's Baltic Fleet.
The oblast is mainly flat, as the highest point is the 230 m (750 ft) Gora Dozor hill near the tripoint of the Poland–Russia border/Lithuania–Russia border.
As an exclave of Russia, it is surrounded by Poland (Pomeranian and Warmian-Masurian Voivodeships), Lithuania (Klaipėda, Marijampolė, and Tauragė Counties) and the Baltic Sea. Even if it is not surrounded by a single country, it can also be considered as a semi-exclave or semi-enclave because it is surrounded by the European Union and NATO. The end of the river Neman forms part of the Lithuania–Russia border.
Notable geographical features include the Curonian Lagoon (shared with Lithuania) and the Vistula Lagoon (shared with Poland). The oblast's largest river is the Pregolya. The river starts as a confluence of the Instruch and the Angrapa and drains into the Baltic Sea through the Vistula Lagoon. Its length, strictly under the name "Pregolya", is 123 km (76 mi); when including the Angrapa, is it 292 km (181 mi) long.

### Climate

The climate of Kaliningrad Oblast gradually transitions from oceanic to humid continental depending on distance from the Baltic Sea moderation. It remains very mild by Russian standards with winters above freezing without the hot summers associated with the Russian interior on similar latitudes. The local climate is slightly wetter than similar latitudes farther west, but infrequent ice days lead to low snow accumulation regardless.

According to a 2012 survey, 34% of the population of Kaliningrad Oblast declared themselves to be "spiritual but not religious", 30.9% adhered to the Russian Orthodox Church, 22% were atheist, and 11.1% followed other religions or did not answer the question, 1% were unaffiliated generic Christians, and 1% were Roman Catholic.
Until 1945, the region was overwhelmingly Lutheran, with a small number of Roman Catholics and Jews. The state church of Prussia was dominant in the region. Although it had been both Reformed and Lutheran since 1817, there was an overwhelming Lutheran majority and very few Reformed adherents in East Prussia.

## Economy

In 2022, the gross regional domestic product of Kaliningrad Oblast was ₽ 738 billion or US$ 10.6 billion and around US$10,000 per capita.
The existence of the oblast's ice-free port and proximity to the European Union are economic advantages. It also has the world's largest deposits of amber. The region has developed its tourism infrastructure and promotes attractions such as the Curonian Spit.
To address the oblast's high rate of unemployment, in 1996 Russian authorities granted the oblast a special economic status that provided tax incentives intended to attract investors. The oblast's economy benefited substantially and boomed. A US$45 million airport terminal was opened. The European Commission provided funds for business projects under its special program for the region. Both economic output and trade with the countries of the EU increased.

### Industry

Car and truck assembly (GM, BMW, Kia, Yuejin by Avtotor) and the production of auto parts are major industries in Kaliningrad Oblast. There are shipbuilding facilities in Kaliningrad and Sovetsk. Food processing is a mature industry in the region, with Miratorg operating a sizeable food processing factory. OKB Fakel, a world leader in the field of Hall thruster development, as well as a leading Russian developer and manufacturer of electric propulsion systems, is based in Neman. The company employs 960 people. General Satellite (GS) is the biggest employer in Gusev city, manufacturing products such as satellite receivers, cardboard packaging, and nanomaterials.

### Natural resources

More than 90% of the world's known amber deposits are in Kaliningrad Oblast. Because of this, many Russians refer to the region as "Amber Land" (Russian: Янтарный Край, romanized: Jantarny Krai). Until recently, raw amber was exported for processing to other countries. In 2013, the Russian government banned the export of raw amber in order to boost the amber processing industry in Russia.
There are small oil reservoirs beneath the Baltic Sea not far from Kaliningrad's shore. Small-scale offshore exploration started in 2004. Poland, Lithuania, and some local NGOs voiced concerns about possible environmental effects.

### Fishing

Fishing is an important regional industry, with big fishing ports in Kaliningrad and Pionersky. There are smaller fishing ports in Svetly and Rybachy.

### Power generation

With the desynchronization of the electricity systems of Lithuania, Latvia and Estonia from the Russian UPS synchronous area in February 2025, and their subsequent connection to the Continental Europe Synchronous Area via Poland, the Kaliningrad electrical grid became islanded from any other system.
Average yearly power consumption in the Kaliningrad Oblast was 3.5 TWh in 2004, of which local power generation provided just 0.235 TWh. The balance was imported from neighbouring countries. A new Kaliningrad power station was built in 2005, providing 50% of the oblast's energy needs. This station was expanded in 2010, making the oblast independent from electricity imports.
In 2008, planning began for the construction of two nuclear power reactors, with costs estimated at €5 billion (US$8 billion). The project was suspended in May 2013. In 2014, the project was abandoned in response to environmental concerns and lack of support.
LNG from St. Petersburg supplied some of the energy in the Oblast.

## Agriculture

The grain blight Fusarium graminearum in the oblast is genetically 3ADON, like the blight's strain in Finland and Saint Petersburg. The researchers who discovered the genetic commonality speculate the cause may be a shared population that is distinct from other F. graminearum populations elsewhere.
