Silesia (Polish: Śląsk, Czech: Slezsko) is a historical landscape, which today is mainly located in the extreme southwest of Poland, but in parts also on the territory of Germany and the Czech Republic. By far the most significant river is the Oder. To the south, Silesia is bordered mainly by the Sudeten and Beskid mountain ranges. Today, almost 8 million people live in Silesia. The largest cities in the region are Wrocław, Opole and Katowice. Before 1945, most of the region was part of Prussia for two hundred years, and before the Silesian Wars (from 1740) it was part of the Habsburg Empire for almost as many years. Silesia is classified into Upper and Lower Silesia.
Austria-Hungary (Hungarian: Osztrák-Magyar Monarchia), also known as Imperial and Royal Hungary Monarchy, was a historical state in Central and Southeastern Europe that existed from 1867 to 1918.
The Kingdom of Prussia existed from 1701 to 1918 and was reigned by the Hohenzollern dynasty. The country was an absolute monarchy from its founding until 1848 and a constitutional monarchy from 1848 until its dissolution. The capital of the Kingdom of Prussia was Berlin. The land was inhabited by about 40 million people. After the November Revolution of 1918 and the abdication of Wilhelm II, the Kingdom dissolved and formed the Free State of Prussia.
The Czech Republic is a country in Central Europe with a population of about 10.5 million people. The capital and largest city of the country is Prague. In the Czech Republic lie the historical landscapes of Bohemia, Moravia and parts of Silesia. In 1918 the state of Czechoslovakia was formed, but the Czech Republic was not founded until 1993. The country has been a member of the EU since 01.05.2004.
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.
