Upper Silesia in the context of "Opole"

Silesians (Silesian: Ślōnzŏki or Ślůnzoki; Silesian German: Schläsinger or Schläsier; German: Schlesier pronounced [ˈʃleːzi̯ɐ] ; Polish: Ślązacy; Czech: Slezané) is both a linguistic as well as a geographical term for the inhabitants of Silesia, a historical region in Central Europe divided by the current national boundaries of Poland, Germany, and Czechia. Historically, the region of Silesia (Lower and Upper) has been inhabited by Polish (West Slavic Lechitic people), Czechs, and Germans. Therefore, the term Silesian can refer to anyone of these ethnic groups. However, in 1945, great demographic changes occurred in the region as a result of the Potsdam Agreement leaving most of the region ethnically Polish and/or Slavic Upper Silesian. The names of Silesia in different languages most likely share their etymology—Polish: Śląsk; German: Schlesien pronounced [ˈʃleːzi̯ən] ; Czech: Slezsko [ˈslɛsko]; Lower Silesian: Schläsing; Silesian: Ślōnsk [ɕlonsk]; Lower Sorbian: Šlazyńska [ˈʃlazɨnʲska]; Upper Sorbian: Šleska [ˈʃlɛska]; Latin, Spanish and English: Silesia; French: Silésie; Dutch: Silezië; Italian: Slesia; Slovak: Sliezsko; Kashubian: Sląsk. The names all relate to the name of a river (now Ślęza) and mountain (Mount Ślęża) in mid-southern Silesia, which served as a place of cult for pagans before Christianization.

Ślęża is listed as one of the numerous Pre-Indo-European topographic names in the region (see old European hydronymy). According to some Polonists, the name Ślęża [ˈɕlɛ̃ʐa] or Ślęż [ɕlɛ̃ʂ] is directly related to the Old Polish words ślęg [ɕlɛŋk] or śląg [ɕlɔŋk], which means dampness, moisture, or humidity. They disagree with the hypothesis of an origin for the name Śląsk [ɕlɔ̃sk] from the name of the Silings tribe, an etymology preferred by some German authors.

Silesia (see names below) is a historical region of Central Europe that lies mostly within Poland, with small parts in the Czech Republic and Germany. Its area is approximately 40,000 km (15,400 sq mi), and the population is estimated at 8,000,000. Silesia is split into two main subregions, Lower Silesia in the west and Upper Silesia in the east.

Situated along the Oder River, with the Sudeten Mountains extending across the southern border, Silesia is a heavily industrialised region rich in mineral and natural resources. The largest city and Lower Silesia's capital is Wrocław; the historic capital of Upper Silesia is Opole. The biggest metropolitan area is the Katowice metropolitan area, the centre of which is Katowice. Parts of the Czech city of Ostrava and the German city of Görlitz are situated within Silesia's borders.

German (Deutsch, pronounced [dɔʏtʃ] ) is a West Germanic language in the Indo-European language family, mainly spoken in Western and Central Europe. It is the majority and official (or co-official) language in Germany, Austria, Switzerland, and Liechtenstein. It is also an official language of Luxembourg, Belgium and the Italian autonomous province of South Tyrol, as well as a recognized national language in Namibia. There are also notable German-speaking communities in other parts of Europe, including: Poland (Upper Silesia), the Czech Republic (North Bohemia), Denmark (North Schleswig), Slovakia (Krahule), Romania, Hungary (Sopron), and France (Alsace). Overseas, sizeable communities of German-speakers are found in the Americas.

German is one of the major languages of the world, with nearly 80 million native speakers and over 130 million total speakers as of 2024. It is the most spoken native language within the European Union. German is the second-most widely spoken Germanic language, after English, both as a first and as a second language. German is also widely taught as a foreign language, especially in continental Europe (where it is the third most taught foreign language after English and French) and in the United States (where it is the third most commonly learned second language in K-12 education and among the most studied foreign languages in higher education after Spanish and French). Overall, German is the fourth most commonly learned second language globally. The language has been influential in the fields of philosophy, theology, science, and technology. It is the second most commonly used language in science and the third most widely used language on websites. The German-speaking countries are ranked fifth in terms of annual publication of new books, with one-tenth of all books (including e-books) in the world being published in German.

Silesian, occasionally called Upper Silesian, is an ethnolect of the Lechitic group spoken in Upper Silesia. While having secured some international recognition as a language, there is a debate on whether Silesian is either a dialect of Polish or a distinct language, and if Silesians are either a regional ethnic group within the Polish nation or a distinct ethnic minority that historically emerged, but later diverged from, the Polish people. Some Silesians identify as a regional ethnic group within the Polish nation, while others view themselves as a distinct ethnic minority. Its vocabulary was significantly influenced by Central German due to the existence of numerous Silesian German speakers in the area prior to World War II and after. The first mentions of Silesian as a distinct lect date back to the 16th century, and the first literature with Silesian characteristics to the 17th century.

Linguistic distinctiveness of Silesian has long been a topic of discussion among Poland's linguists, especially after all of Upper Silesia was included within the Polish borders following World War II. Some regard it as one of the four major dialects of Polish, while others classify it as a separate regional language, distinct from Polish. The dispute over the status of Silesian is considered to be of purely political character. According to the official data from the 2021 Polish census, 467 145 people use Silesian on daily basis. Internationally, Silesian has been fully recognized as a language since 2007, when it was accorded the ISO 639-3 registration code szl.

Katowice metropolitan area, also known as Upper Silesian metropolitan area (Polish: górnośląski obszar metropolitalny), is the metropolitan area of Katowice and its urban area, with a population of around 2.5 million (2023). It lies within the areas of the historic regions of Upper Silesia, Kraków Basin [pl] and Dąbrowa Basin. It is sometimes considered a part of the polycentric Katowice-Ostrava metropolitan area, which has a population of 5.3 million people (2002). Also this is (with Kraków metropolitan area among others) a part of Kraków-Katowice-Ostrava metropolitan region [Wikidata], which has a population of around 6.8 million.

The High German languages (German: hochdeutsche Mundarten, i.e. High German dialects), or simply High German (Hochdeutsch [ˈhoːxˌdɔɪ̯t͡ʃ] ) – not to be confused with Standard High German which is commonly also called "High German" – comprise the varieties of German spoken south of the Benrath and Uerdingen isoglosses, i.e., in central and southern Germany, Austria, Liechtenstein, Switzerland, Luxembourg, and eastern Belgium, as well as in neighbouring portions of France (Alsace and northern Lorraine), Italy (South Tyrol), the Czech Republic (Bohemia), and Poland (Upper Silesia). They are also spoken in diasporas in Romania, Russia, Canada, the United States, Brazil, Argentina, Mexico, Chile, and Namibia.

High German is marked by the High German consonant shift, separating it from Low German (Low Saxon) and Low Franconian (including Dutch) within the continental West Germanic dialect continuum. "Low" and "high" refer to the lowland and highland geographies typically found in the two areas.

The Principality of Opava (Czech: Opavské knížectví; Polish: Księstwo Opawskie) or Duchy of Troppau (German: Herzogtum Troppau) was a historic territory split off from the Margraviate of Moravia before 1269 by King Ottokar II of Bohemia to provide for his natural son, Nicholas I. The Opava territory thus had not been part of the original Polish Duchy of Silesia in 1138, and was first ruled by an illegitimate offshoot of the Bohemian Přemyslid dynasty, not by the Silesian Piasts like many of the neighbouring Silesian duchies. Its capital was Opava (Troppau) in the modern-day Czech Republic.

From 1337 onwards, the Přemyslid dukes also ruled the adjacent former Piast Duchy of Racibórz, whereupon Opava became united with the Upper Silesian lands. When the Opava branch became extinct in 1464, it fell back to the Bohemian Crown, from 1526 part of the Habsburg monarchy. In the final three centuries of its existence, the duchy was ruled by the House of Liechtenstein. It was dissolved with the Austro-Hungarian Empire in 1918, but the title of Duke of Troppau and Jägerndorf still exists, belonging to a present-day monarch, Prince Hans-Adam II of Liechtenstein. The Duchy of Jägerndorf (Krnov) was another of the Silesian duchies.

George Frederick of Brandenburg-Ansbach (German: Georg Friedrich der Ältere; 5 April 1539 in Ansbach – 25 April 1603) was Margrave of Ansbach and Bayreuth, as well as Regent of Prussia. He was the son of George, Margrave of Brandenburg-Ansbach and a member of the House of Hohenzollern. He married firstly, in 1559, Elisabeth of Brandenburg-Küstrin (29 August 1540 – 8 March 1578). He married secondly, in 1579, Sophie of Brunswick-Lüneburg (30 October 1563 – 1639), daughter of William of Brunswick-Lüneburg and Dorothea of Denmark.

George Frederick reigned in his native Ansbach, Franconia and Jägerndorf, Upper Silesia since 1556 and, after the death of his cousin Albert Alcibiades in 1557, also in Kulmbach. He took over the administration of the Duchy of Prussia in 1577, when the then-reigning Duke Albert Frederick became ill.
