Silesia (see names below) is a historical region of Central Europe that now lies mostly within Poland, with small parts in the Czech Republic and Germany. Its area is approximately 40,000 km2 (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 historical borders.
Silesia’s culture reflects its complex history and diverse influences, comprising Polish, Czech, and German elements. The region is known for its distinctive Silesian language (still spoken by a minority in Upper Silesia), richly decorated folk costumes, hearty regional cuisine, and a mix of Gothic, Baroque, and industrial-era architecture seen in its cities and towns. The region contains many historical landmarks and UNESCO World Heritage Sites. Silesia's borders and national affiliation have changed over time, both when it was a hereditary possession of noble houses and after the rise of modern nation-states, resulting in an abundance of castles and strongholds, especially in the Jelenia Góra valley.
First held by Great Moravia at the end of the 9th century and Bohemia in the early 10th century, Silesia was incorporated into the early Polish state, and after its fragmentation in the 12th century it formed the Duchy of Silesia. As a result of further fragmentation, it was divided into individual duchies, ruled by various lines of the Polish Piast dynasty. In the 14th century, it became a constituent part of the Bohemian Crown Lands under the Holy Roman Empire, which passed to the Austrian Habsburg Monarchy in 1526; however, a number of duchies remained under the rule of Polish dukes (Piast, Jagiellon, Sobieski) as formal Bohemian fiefdoms. As a result of the Silesian Wars, the region was annexed by Prussia from Austria in 1742 and subsequently became a part of the German Empire in 1871.
After World War I, when the Poles and Czechs regained their independence, the easternmost part of Upper Silesia became part of Poland by the decision of the Entente Powers after insurrections by Poles and the Upper Silesian plebiscite, while the remaining former Austrian parts of Silesia were divided between Czechoslovakia and Poland. During World War II, as a result of German occupation the entire region was under control of Nazi Germany. In 1945, after World War II, most of the German-held Silesia was transferred to Polish jurisdiction by the Potsdam Agreement between the victorious Allies and became part of Poland. The small Lusatian strip west of the Oder–Neisse line, which had belonged to Silesia since 1815, became part of East Germany.
As the result of the forced population shifts of 1945–48, today's inhabitants of Silesia speak the national languages of their respective countries. Previously German-speaking Lower Silesia has developed a new mixed Polish dialect and novel costumes. There is ongoing debate about whether the Silesian language, common in Upper Silesia, should be considered a dialect of Polish or a separate language. The Lower Silesian German dialect is nearing extinction due to its speakers' expulsion.

Etymology
The names of Silesia in different languages most likely share their etymology—Polish: Śląsk [ɕlɔ̃sk] ; German: Schlesien [ˈʃleːzi̯ən] ; Czech: Slezsko [ˈslɛsko]; Lower Silesian: Schläsing; Silesian: Ślōnsk [ɕlonsk]; Lower Sorbian: Šlazyńska [ˈʃlazɨnʲska]; Upper Sorbian: Šleska [ˈʃlɛska]; Slovak: Sliezsko; Latin, Spanish and English: Silesia; French: Silésie; Dutch: Silezië; Italian: Slesia. 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 from the name of the Silings tribe.
In Polish common usage, "Śląsk" refers to traditionally Polish Upper Silesia and today's Silesian Voivodeship, but less to Lower Silesia, which is different from Upper Silesia in many respects as its population was predominantly German-speaking from around the mid-19th century until 1945–48.
History
In the fourth century BC from the south, through the Kłodzko Valley, the Celts entered Silesia, and settled around Mount Ślęża near modern Wrocław, Oława and Strzelin.
Germanic Lugii tribes were first recorded within Silesia in the 1st century BC. West Slavs and Lechites arrived in the region around the 7th century, and by the early ninth century, their settlements had stabilized. Local West Slavs started to erect boundary structures like the Silesian Przesieka and the Silesia Walls. The eastern border of Silesian settlement was situated to the west of the Bytom, and east from Racibórz and Cieszyn. East of this line dwelt a closely related Lechitic tribe, the Vistulans. Their northern border was in the valley of the Barycz River, north of which lived the Western Polans tribe who gave Poland its name.
The first known states in Silesia were Greater Moravia and Bohemia. In the 10th century, the Polish ruler Mieszko I of the Piast dynasty incorporated Silesia into the newly established Polish state. In 1000, the Diocese of Wrocław was established as the oldest Catholic diocese in the region, and one of the oldest dioceses in Poland, subjugated to the Roman Catholic Archdiocese of Gniezno. Poland repulsed German invasions of Silesia in 1017 at Niemcza and in 1109 at Głogów. During the Fragmentation of Poland, Silesia and the rest of the country were divided into many smaller duchies ruled by various Silesian dukes. In 1178, parts of the Duchy of Kraków around Bytom, Oświęcim, Chrzanów, and Siewierz were transferred to the Silesian Piasts, although their population was primarily Vistulan and not of Silesian descent.
Walloons came to Silesia as one of the first foreign immigrant groups in Poland, probably settling in Wrocław since the 12th century, with further Walloon immigrants invited by Duke Henry the Bearded in the early 13th century. Since the 13th century, German cultural and ethnic influence increased as a result of immigration from German-speaking states of the Holy Roman Empire.
The first granting of municipal privileges in Poland took place in the region, in the town of Złotoryja by Henry the Bearded. Medieval municipal rights modeled after Lwówek Śląski and Środa Śląska, both established by Henry the Bearded, became the basis of municipal form of government for several cities and towns in Poland, and two of five local Polish variants of medieval town rights. The Book of Henryków, which contains the earliest known sentence written in the Polish language, as well as a document which contains the oldest printed text in Polish, were created in Henryków and Wrocław in Silesia, respectively.
Ethnic history
Modern Silesia is inhabited by Poles, Silesians, Germans, and Czechs. Germans first came to Silesia during the Late Medieval Ostsiedlung. The last Polish census of 2011 showed that the Silesians are the largest ethnic or national minority in Poland, Germans being the second; both groups are located mostly in Upper Silesia. The Czech part of Silesia is inhabited by Czechs, Moravians, Silesians, and Poles.
In the early 19th century the population of the Prussian part of Silesia was between 2/3 and 3/4 German-speaking, between 1/5 and 1/3 Polish-speaking, with Sorbs, Czechs, Moravians and Jews forming other smaller minorities (see Table 1. below).
Before the Second World War, Silesia was inhabited mostly by Germans, with Poles a large minority, forming a majority in Upper Silesia. Silesia was also the home of Czech and Jewish minorities. The German population tended to be based in the urban centres and in the rural areas to the north and west, whilst the Polish population was mostly rural and could be found in the east and in the south.
Ethnic structure of Prussian Upper Silesia (Opole regency) during the 19th century and the early 20th century can be found in Table 2.:
The Austrian part of Silesia had a mixed German, Polish and Czech population, with Polish-speakers forming a majority in Cieszyn Silesia.
Historically, Silesia was about equally split between Catholics and Protestants (overwhelmingly Lutherans). In an 1890 census taken in the German part, Catholics made up a slight majority of 53%, while the remaining 47% were almost entirely Lutheran. Geographically speaking, Upper Silesia was mostly Catholic except for some of its northwestern parts, which were predominantly Lutheran. Lower Silesia was mostly Lutheran except for the Glatzer Land (now Kłodzko County). Generally speaking, the population was mostly Protestant in the western parts, and it tended to be more Catholic the further east one went. In Upper Silesia, Protestants were concentrated in larger cities and often identified as German. After World War II, the religious demographics changed drastically as Germans, who constituted the bulk of the Protestant population, were forcibly expelled. Poles, who were mostly Catholic, were resettled in their place. Today, Silesia remains predominantly Catholic.
Geography
Most of Silesia is relatively flat, although its southern border is generally mountainous. It is primarily located in a swath running along both banks of the upper and middle Oder (Odra) River, but it extends eastwards to the upper Vistula River. The region also includes many tributaries of the Oder, including the Bóbr (and its tributary the Kwisa), the Barycz and the Nysa Kłodzka. The Sudeten Mountains run along most of the southern edge of the region, though at its south-eastern extreme it reaches the Silesian Beskids and Moravian-Silesian Beskids, which belong to the Carpathian Mountains range.
Historically, Silesia was bounded to the west by the Kwisa and Bóbr Rivers, while the territory west of the Kwisa was in Upper Lusatia (earlier Milsko). However, because part of Upper Lusatia was included in the Province of Silesia in 1815, in Germany Görlitz, Niederschlesischer Oberlausitzkreis and neighbouring areas are considered parts of historical Silesia. Those districts, along with Poland's Lower Silesian Voivodeship and parts of Lubusz Voivodeship, make up the geographic region of Lower Silesia.
Silesia has undergone a similar notional extension at its eastern extreme. Historically, it extended only as far as the Brynica River, which separates it from Zagłębie Dąbrowskie in the Lesser Poland region. However, to many Poles today, Silesia (Śląsk) is understood to cover all of the area around Katowice, including Zagłębie. This interpretation is given official sanction in the use of the name Silesian Voivodeship (województwo śląskie) for the province covering this area. In fact, the word Śląsk in Polish (when used without qualification) now commonly refers exclusively to this area (also called Górny Śląsk or Upper Silesia).
As well as the Katowice area, historical Upper Silesia also includes the Opole region (Poland's Opole Voivodeship) and Czech Silesia. Czech Silesia consists of a part of the Moravian-Silesian Region and the Jeseník District in the Olomouc Region.
Natural resources
Silesia is a resource-rich and populous region. Since the middle of the 18th century, coal has been mined. The industry had grown while Silesia was part of Germany, and peaked in the 1970s under the People's Republic of Poland. During this period, Silesia became one of the world's largest producers of coal, with a record tonnage in 1979. Coal mining declined during the next two decades, but has increased again following the end of Communist rule.
The 41 coal mines in Silesia are mostly part of the Upper Silesian Coal Basin, which lies in the Silesian Upland. The coalfield has an area of about 4,500 km2 (1,700 mi2). Deposits in Lower Silesia have proven to be difficult to exploit and the area's unprofitable mines were closed in 2000. In 2008, an estimated 35 billion tonnes of lignite reserves were found near Legnica, making them some of the largest in the world.
From the fourth century BC, iron ore has been mined in the upland areas of Silesia. The same period had lead, copper, silver, and gold mining. Zinc, cadmium, arsenic, and uranium have also been mined in the region. Lower Silesia features large copper mining and processing between the cities of Legnica, Głogów, Lubin, and Polkowice. In the Middle Ages, gold (Polish: złoto) and silver (Polish: srebro) were mined in the region, which is reflected in the names of the former mining towns of Złotoryja, Złoty Stok and Srebrna Góra.
The region is known for stone quarrying to produce limestone, marl, marble, and basalt.
The region also has a thriving agricultural sector, which produces cereals (wheat, rye, barley, oats, corn), potatoes, rapeseed, sugar beets and others. Milk production is well developed. The Opole Silesia has for decades occupied the top spot in Poland for their indices of effectiveness of agricultural land use.
Mountainous parts of southern Silesia feature many significant and attractive tourism destinations (e.g., Karpacz, Szczyrk, Wisła). Silesia is generally well forested. This is because greenness is generally highly desirable by the local population, particularly in the highly industrialized parts of Silesia.
Demographics
Silesia has been historically diverse in every aspect. Nowadays, the largest part of Silesia is located in Poland; it is often cited as one of the most diverse regions in that country.
The United States Immigration Commission, in its Dictionary of Races or Peoples (published in 1911, during a period of intense immigration from Silesia to the United States), considered Silesian as a geographical (not ethnic) term, denoting the inhabitants of Silesia. It is also mentioned the existence of both Polish Silesian and German Silesian dialects in that region.
Cities and towns
The following table includes the cities and towns in Silesia with a population greater than 20,000 (2026).

Flags and coats of arms
The emblems of Lower Silesia and Upper Silesia originate from the emblems of the Piasts of Lower Silesia and Upper Silesia. The coat of arms of Upper Silesia depicts the golden eagle on the blue shield. The coat of arms of Lower Silesia depicts a black eagle on a golden (yellow) shield.
Flags with their colors refer to the coat of arms of Silesia.
