Brandenburg in the context of "Neukölln"

Sorbs (Upper Sorbian: Serbja; Lower Sorbian: Serby; German: Sorben pronounced [ˈzɔʁbn̩] ; Czech: Lužičtí Srbové; Polish: Serbołużyczanie; also known as Lusatians, Lusatian Serbs and Wends) are an indigenous West Slavic ethnic group predominantly inhabiting the parts of Lusatia located in the German states of Saxony and Brandenburg. Sorbs traditionally speak the Sorbian languages (also known as "Wendish" and "Lusatian"), which are closely related to Czech and Lechitic languages. Upper Sorbian and Lower Sorbian are officially recognized minority languages in Germany.

In the Early Middle Ages, the Sorbs formed their own principality, which later shortly became part of the early West Slavic Samo's Empire and Great Moravia, as were ultimately conquered by the East Francia (Sorbian March) and Holy Roman Empire (Saxon Eastern March, Margravate of Meissen, March of Lusatia). From the High Middle Ages, they were ruled at various times by the closely related Poles and Czechs, as well as the more distant Germans and Hungarians. Due to a gradual and increasing assimilation between the 17 and 20 centuries, virtually all Sorbs also spoke German by the early 20 century. In the newly created German nation state of the late 19 and early 20 centuries, policies were implemented in an effort to Germanize the Sorbs. These policies reached their climax under the Nazi regime, who denied the existence of the Sorbs as a distinct Slavic people by referring to them as "Sorbian-speaking Germans". The community is divided religiously between Roman Catholicism (the majority) and Lutheranism. The former Minister President of Saxony Stanislaw Tillich is of Sorbian origin.

The Kingdom of Bohemia (Czech: České království), sometimes referenced in English literature as the Czech Kingdom, was a medieval and early modern monarchy in Central Europe. It was the predecessor state of the modern Czech Republic.

The Kingdom of Bohemia was an Imperial State in the Holy Roman Empire. The Bohemian king was a prince-elector of the empire. The kings of Bohemia, besides the region of Bohemia itself, also ruled other lands belonging to the Bohemian Crown, which at various times included Moravia, Silesia, Lusatia, and parts of Saxony, Brandenburg, and Bavaria.

Berlin is the capital of Germany, as well as its largest city by both area and population. With 3.7 million inhabitants, it has the highest population within its city limits of any city in the European Union. The city is also one of the states of Germany, being the third-smallest state in the country by area. Berlin is surrounded by the state of Brandenburg, and Brandenburg's capital Potsdam is nearby. The urban area of Berlin has a population of over 4.6 million, making it the most populous in Germany. The Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's second-largest metropolitan region after the Rhine-Ruhr region, as well as the fifth-biggest metropolitan region by GDP in the European Union.

Berlin was built along the banks of the Spree river, which flows into the Havel in the western borough of Spandau. The city includes lakes in the western and southeastern boroughs, the largest of which is Müggelsee. About one-third of the city's area is composed of forests, parks and gardens, rivers, canals, and lakes.

The new states of Germany (German: die neuen Länder / die neuen Bundesländer) are the five re-established states of the former German Democratic Republic (GDR) that unified with the Federal Republic of Germany (FRG) with its 10 "old states" upon German reunification on 3 October 1990.

The new states, which were dissolved by the GDR government in 1952 and re-established in 1990, are Brandenburg, Mecklenburg-Western Pomerania, Saxony, Saxony-Anhalt, and Thuringia. The state of Berlin, the result of a merger between East and West Berlin, is usually not considered one of the new states although a number of its residents are former East Germans and some of its areas were in the former East Berlin. There have been 16 states in Germany since reunification.

Lower Saxony is a German state (Land) in northwestern Germany. It is the second-largest state by land area, with 47,614 km (18,384 sq mi), and fourth-largest in population (8 million in 2021) among the 16 Länder of the Federal Republic of Germany. In rural areas, Northern Low Saxon and Saterland Frisian are still spoken, though by declining numbers of people.

Lower Saxony borders on (from north and clockwise) the North Sea, the states of Schleswig-Holstein, Hamburg, Mecklenburg-Vorpommern, Brandenburg, Saxony-Anhalt, Thuringia, Hesse and North Rhine-Westphalia, and the Netherlands. Furthermore, the state of Bremen forms two enclaves within Lower Saxony, one being the city of Bremen, the other its seaport, Bremerhaven (which is a semi-exclave, as it has a coastline). Lower Saxony thus borders more neighbours than any other single Bundesland. The state's largest cities are the state capital Hanover, Braunschweig (Brunswick), Oldenburg, Osnabrück, Wolfsburg, Göttingen, Salzgitter, Hildesheim, mainly situated in its central and southern parts, except Oldenburg.

Lower Sorbian (endonym: dolnoserbšćina) is a West Slavic minority language spoken in eastern Germany in the historical province of Lower Lusatia, today part of Brandenburg.

Standard Lower Sorbian is one of the two literary Sorbian languages, the other being the more widely spoken Upper Sorbian. The Lower Sorbian literary standard was developed in the 18th century, based on a southern form of the Cottbus dialect. The standard variety of Lower Sorbian has received structural influence from Upper Sorbian. Lower Sorbian differs from Upper Sorbian at all levels of the language system: in phonetics (the spread of the plosive consonant g; the merger of the affricate č with the hardened fricative c; the change of hard r after p, t, k into hard š; the change of ć, ʒ́ into soft fricative sibilants ś, ź), in morphology (the presence of the supine; absence of aorist and imperfect forms in dialects), and in vocabulary (bom "tree"; twarc "carpenter"; gluka "happiness" and so on, contrasted with the corresponding Upper Sorbian štom, ćěsla, zbožo). The formation of the Lower Sorbian literary norm was greatly influenced by the Upper Sorbian language. Unlike Upper Sorbian, Lower Sorbian is less standardized and strictly codified, characterized by instability and greater variability.

The Havel (German: [ˈhaːfl̩] ) is a river in northeastern Germany, flowing through the states of Mecklenburg-Vorpommern, Brandenburg, Berlin and Saxony-Anhalt. The 325-kilometre-long (202 mi) Havel is a right tributary of the Elbe. However, the direct distance from its source to its mouth is only 94 kilometres (58 mi). For much of its length, the Havel is navigable; it provides an important link in the waterway connections between the east and west of Germany, as well as beyond.

The Black Elster or Schwarze Elster (German: [ˌʃvaʁtsə ˈʔɛlstɐ] ; Lower Sorbian: Carny Halšter; Upper Sorbian: Čorny Halštrow) is a 179-kilometre (111 mi) long river in eastern Germany, in the states of Saxony, Brandenburg and Saxony-Anhalt. It is a right tributary of the Elbe. Its source is in the Upper Lusatia region, near Elstra/Halštrow.

The Black Elster flows through the cities Kamenz/Kamjenc, Hoyerswerda/Wojerecy, Senftenberg/Zły Komorow, Lauchhammer, Elsterwerda, Bad Liebenwerda, Herzberg and Jessen. It flows into the river Elbe at Elster (Elbe), upstream from Wittenberg.

Pomerania (Polish: Pomorze [pɔˈmɔʐɛ] ; German: Pommern [ˈpɔmɐn] ; Kashubian: Pòmòrskô; Swedish: Pommern) is a historical region on the southern shore of the Baltic Sea in Central Europe, split between Poland and Germany. The central and eastern part belongs to the West Pomeranian, Pomeranian and Kuyavian-Pomeranian voivodeships of Poland, while the western part belongs to the German states of Mecklenburg-Western Pomerania and Brandenburg.

Pomerania's historical border in the west is the Mecklenburg-Western Pomeranian border Urstromtal, which now constitutes the border between the Mecklenburgian and Pomeranian part of Mecklenburg-Western Pomerania, while it is bounded by the Vistula River in the east. The easternmost part of Pomerania is alternatively known as Pomerelia, consisting of four sub-regions: Kashubia inhabited by ethnic Kashubians, Kociewie, Tuchola Forest and Chełmno Land.

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.
