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.
