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

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.

It was a destination for German artists and intelligentsia 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 :de:Ernst Hasse (Politiker), Ernst Hasse criticised the lack of folk identity and imagined community: "It is the case that there is almost no common folk identity andsmannschaftenamong the Poseners and Prussians at all. ..Who can recognise a Posener or Prussian by dialect and character?

. 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

s 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 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.

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):

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.

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

. 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.

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

deposits are in Kaliningrad Oblast. Because of this, many Russians refer to the region as "Amber Land" (). 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.
