Ostpreußen ist der Name der ehemaligen, bis 1945 bestehenden östlichsten preußischen Provinz, deren Ausdehnung (ungeachtet historisch leicht wechselnder Grenzverläufe) ungefähr der historischen Landschaft Preußen entspricht. Die Bezeichnung kam erst in der zweiten Hälfte des 18. Jahrhunderts in Gebrauch, als neben dem 1701 zum Königreich erhobenen Herzogtum Preußen mit seiner Hauptstadt Königsberg weitere, zuvor polnische Gebiete im Westen (beispielsweise das sog. Preußen Königlichen Anteils mit dem Ermland und Pommerellen) zu Brandenburg-Preußen kamen und die neue Provinz Westpreußen bildeten.
Heutzutage gehört das Gebiet der ehemaligen preußischen Provinz überwiegend zu Russland (Oblast Kaliningrad) und Polen (Woiwodschaft Ermland-Masuren). Das ehemalige sog. Memelland (auch Memelgebiet, lit. Klaipėdos kraštas) kam erstmals 1920 und erneut ab 1945 zu Litauen.
The Baltic States is a region in the north-east of Europe and is composed of the three states Estonia, Latvia and Lithuania. The Baltic States are inhabited by almost 6 million people.
Poland is located on the Baltic Sea and is the largest state (population in 2023: 37,636,508, area: 313,964 km²) in East Central Europe. The name of the state is derived from the West Slavic Polans, who brought more and more territories under their rule from the 9th century onwards, which were known as Duchy of Poland in the 10th century. Under Mieszko (ca. 960-992), the extent of the country reached approximately its current borders. He was at times subject to tribute to the German Emperor, at least for parts of his land. Poland probably adopted Christianity in 966 and from 1025 it was a kingdom. Between 1138 and 1295, the country was fragmented as a result of inheritance disputes. The extinction of the ruling Piast dynasty led to a Polish-Hungarian personal union in 1370, which was replaced by a Polish-Lithuanian dual monarchy as early as 1386 due to pressure from the Polish nobility. The growing role of the nobility resulted in an elective monarchy in 1572. However, the disunity of the nobility led to the three partitions of Poland (1772-1795) between Prussia, Russia and the Habsburg Monarchy. Poland only became independent after the end of the First World War in 1918 and lost its independence in 1939 after the German attack from the west at the beginning of the Second World War and the Russian invasion from the east. From 1945-1989 it was a satellite state of the Soviet Union. Poland has been a member of the European Union since 2004.
The Russian Federation is the largest territorial state in the world and is inhabited by about 145 million people. The capital and largest city is Moscow, with about 11.5 million inhabitants, followed by St. Petersburg with more than 5.3 million inhabitants. The majority of the population lives in the European part of Russia, which is much more densely populated than the Asian part.
Since 1992, the Russian Federation has been the successor state to the Russian Soviet Republic (Russian Socialist Federative Soviet Republic, RSFSR), by far the largest constituent state of the former Soviet Union. It is also the legal successor of the Soviet Union in the sense of international law.
Estonia is a country in north-eastern Europe. It is inhabited by around 1.3 million people and borders Latvia, Russia and the Baltic Sea. The most populous city and capital is Tallinn.
Today's Estonian state only regained its political independence in 1991 as a result of the so-called “Singing Revolution” in the Baltic states and in the wake of the collapse of the Soviet Union. Estonian independence was first proclaimed in 1918 and achieved through the “Estonian War of Independence” (1918-1920). As early as 1940, this first Estonian state was replaced by the “Estonian Soviet Socialist Republic”, which was founded under Soviet occupation. With an interruption due to the German occupation during the Second World War (1941-1944) and with slightly different borders, it was a constituent republic of the Soviet Union until 1991. Before 1918, the territory of present-day Estonia was part of the Russian Empire, with its northern part forming the Baltic Governorate of Estonia and its southern part the northern half of the Baltic Governorate of Livonia. In the High and Late Middle Ages and at the beginning of the early modern period, parts of today's country were also under Swedish, Danish and Polish rule, while the Livonian part was also under the sovereignty of the Teutonic Order until 1561.
Estonia has been part of the European Union and NATO since 2004.
Latvia is a Baltic state in the north-east of Europe and is home to about 1.9 million inhabitants. The capital of the country is Riga. The state borders in the west on the Baltic Sea and on the states of Lithuania, Estonia, Russia and Belarus. Latvia has been a member of the EU since 01.05.2004 and only became independent in the 19th century.
Lithuania is a Baltic state in northeastern Europe and is home to approximately 2.8 million people. Vilnius is the capital and most populous city of Lithuania. The country borders the Baltic Sea, Poland, Belarus, Russia and Latvia. Lithuania only gained independence in 1918, which the country reclaimed in 1990 after several decades of incorporation into the Soviet Union.
