Lusatian Neisse in the context of "Liberec"

Oder–Neisse line (German: Oder-Neiße-Grenze, Polish: granica na Odrze i Nysie Łużyckiej) is an unofficial term for the modern border between Germany and Poland. The line generally follows the Oder and Lusatian Neisse rivers, meeting the Baltic Sea in the north. A small portion of Polish territory does fall west of the line, including the cities of Szczecin and Świnoujście (German: Stettin and Swinemünde).

In post-war Poland the government described the Oder–Neisse line as the result of tough negotiations between Polish Communists and Stalin. However, according to the modern Institute of National Remembrance, Polish aspirations had no impact on the outcome; rather the idea of a westward shift of the Polish border was adopted synthetically by Stalin, who was the final arbiter in the matter. Stalin's political goals as well as his desire to foment enmity between Poles and Germans influenced his idea of a swap of western for eastern territory, thus ensuring control over both countries. As with before the war, some fringe groups advocated restoring the old border between Poland and Germany.

The Sudetes (/suːˈdiːtiːz/ soo-DEE-teez), also known as the Sudeten Mountains or Sudetic Mountains, is a geomorphological subprovince of the Bohemian Massif province in Central Europe, shared by the Czech Republic, Poland and Germany. They consist mainly of mountain ranges and are the highest part of the Bohemian Massif. They stretch from the Saxon capital of Dresden in the northwest across to the region of Lower Silesia in Poland and to the city of Ostrava in the Czech Republic in the east. Geographically the Sudetes are a Mittelgebirge with some characteristics typical of high mountains. Its plateaus and subtle summit relief makes the Sudetes more akin to mountains of Northern Europe than to the Alps.

In the east of the Sudetes, the Moravian Gate and Ostrava Basin separates from the Carpathian Mountains. The Sudetes' highest mountain is Sněžka (Polish: Śnieżka) at 1,603 m (5,259 ft), which is also the highest mountain of the Czech Republic, Bohemia, Silesia, and Lower Silesian Voivodeship. It lies in the Giant Mountains on the border between the Czech Republic and Poland. Praděd (1,491 m/4,893 ft) in the Hrubý Jeseník mountains is the highest mountain of Moravia. Lusatia's highest point (1,072 m/3,517 ft) lies on Smrk mountain in the Jizera Mountains, and the Sudetes' highest mountain in Germany, which is also the country's highest mountain east of the river Elbe, is Lausche (793 m/2,600 ft) in the Lusatian Mountains. The most notable rivers rising in the Sudetes are the Elbe, Oder, Spree, Morava, Bóbr, Lusatian Neisse, Eastern Neisse, Jizera and Kwisa. The highest parts of the Sudetes are protected by national parks; Karkonosze and Stołowe (Table) in Poland and Krkonoše in the Czech Republic.

Lusatia (/luːˈseɪʃiə, -ʃə/; German: Lausitz [ˈlaʊzɪts] ; Polish: Łużyce [wuˈʐɨt͡sɛ] ; Upper Sorbian: Łužica [ˈwuʒitsa]; Lower Sorbian: Łužyca [ˈwuʒɨtsa]; Czech: Lužice [ˈluʒɪt͡sɛ]), otherwise known as Sorbia, is a region in Central Europe, territorially split between Germany and Poland. Lusatia stretches from the Bóbr and Kwisa rivers in the east to the Pulsnitz and Black Elster rivers in the west, and is located within the German states of Saxony and Brandenburg and the Polish voivodeships of Lower Silesia and Lubusz. Major rivers of Lusatia are the Spree and the Lusatian Neisse, which defines the border between Germany and Poland. The Lusatian Mountains of the Western Sudetes separate Lusatia from Bohemia (Czech Republic) in the south. Lusatia is traditionally divided into Upper Lusatia, the hilly southern part, and Lower Lusatia, the flat northern part.

The areas east and west along the Spree in the German part of Lusatia are home to the Slavic Sorbs, one of Germany’s four officially recognized indigenous ethnic minorities. The Upper Sorbs inhabit Saxon Upper Lusatia, and the Lower Sorbs Brandenburgian Lower Lusatia. Upper and Lower Sorbian are spoken in the German parts of Upper and Lower Lusatia respectively, and the signage there is mostly bilingual.

Görlitz ([ˈɡœʁlɪts] ; Lower Sorbian: Zgórjelc; Upper Sorbian: Zhorjelc [ˈzhɔʁʲɛlts] ; Polish: Zgorzelec [zɡɔˈʐɛ.lɛt͡s] ; Czech: Zhořelec [ˈzɦor̝ɛlɛt͡s]; East Lusatian: Gerlz, Gerltz, Gerltsch) is a town in the German state of Saxony. It is on the river Lusatian Neisse and is the largest town in Upper Lusatia, the second-largest town in the region of Lusatia after Cottbus, and the largest town in the German part of the region of Silesia. Görlitz is the easternmost town in Germany and lies opposite the Polish town of Zgorzelec, which was the eastern part of Görlitz until 1945. The town has approximately 56,000 inhabitants, which make Görlitz the sixth-largest town in Saxony. It is the seat of the district of Görlitz. Together with Zgorzelec it forms the Euro City of Görlitz/Zgorzelec, which has a combined population of around 86,000.

Görlitz, first mentioned in 1071, developed as a key trading town on the Via Regia route linking Western and Eastern Europe. In the Late Middle Ages, it prospered through the cloth trade and became a member of the Lusatian League, enjoying considerable autonomy. The town came under Bohemian, Hungarian, Austrian and Saxon rule before becoming part of Prussia in 1815 after the Congress of Vienna. During World War II, Görlitz was spared major destruction, but the new Oder–Neisse line in 1945 divided it from its eastern districts, which became Zgorzelec in Poland. In the GDR era, Görlitz was a border town with limited cross-border contact, but after German reunification and Poland’s EU accession, cooperation with Zgorzelec increased. Today, Görlitz is renowned for its well-preserved historic architecture and frequent use as a film location.

Herrnhut (German: [ˈhɛʁnhuːt] ; Upper Sorbian: Ochranow; Czech: Ochranov; Upper Lusatian: Harrnhutt, Harrnutt) is a town of around 6,000 inhabitants in Upper Lusatia, in the district of Görlitz, in eastern Saxony, Germany. The town is mainly known as the place of origin of the community of the Moravian Church (established by Nicolas Ludwig, Count von Zinzendorf in 1722), and of the Moravian Stars (Herrnhuter Sterne).

In 2016, the town was awarded the honorary title European City of the Reformation by the Communion of Protestant Churches in Europe, and in 2024, Herrnhut was inscribed on the World Heritage List as part of the serial site "Moravian Church Settlements" (Siedungen der Herrnhuter Brüdergemeinde) alongside Christiansfeld (Denmark), Bethlehem (USA) and Gracehill (Northern Ireland). Herrnhut lies between the larger towns of Löbau and Zittau in the hilly foreland of the Zittau Mountains on the Petersbach, the longest headstream of the Pließnitz, a tributary of the Lusatian Neisse.

Vratislavice nad Nisou (German: Maffersdorf) is a self-governing borough of the city of Liberec in the Czech Republic. As of 2021, it has about 8,900 inhabitants. It straddles the Lusatian Neisse river between Liberec and Jablonec nad Nisou, around 3.5 km south-east of Liberec city centre.
