Its area is approximately {{convert|40000|km2|-2|abbr=on}}, 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. 

Silesia’s culture reflects its complex history and diverse influences, blending 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 [[National costumes of Poland|costumes]], hearty regional [[Silesian cuisine|cuisine]], and a mix of Gothic, Baroque, and industrial-era [[Silesian architecture|architecture]] seen in its cities and towns. The largest city of the region is [[Wrocław]].

Silesia is situated along the [[Oder]] River, with the [[Sudeten Mountains]] extending across the southern border. The region contains many historical landmarks and [[UNESCO World Heritage Site]]s. It is also rich in mineral and natural resources, and includes several important industrial areas. 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 within Silesia's borders.

Silesia's borders and national affiliation have changed over time, both when it was a hereditary possession of [[feudalism|noble houses]] and after the rise of modern [[nation-states]], resulting in an abundance of [[List of castles in Poland|castles]], especially in the [[List of castles and palaces in Jelenia Góra valley|Jelenia Góra valley]]. The first known states to hold power in Silesia were probably those of [[Greater Moravia]] at the end of the 9th century and [[Duchy of Bohemia|Bohemia]] early in the 10th century. In the 10th century, Silesia was incorporated into the early Polish state, and after its fragmentation in the 12th century it formed the [[Duchy of Silesia]], a provincial duchy of Poland. As a result of further fragmentation, Silesia was divided into many [[Duchies of Silesia|duchies]], ruled by various lines of the Polish [[Piast dynasty]]. In the 14th century, it became a constituent part of the [[Lands of the Bohemian Crown|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 from the houses of Piast, [[Jagiellonian dynasty|Jagiellon]] and [[House of Sobieski|Sobieski]] as formal [[Bohemia|Bohemian]] fiefdoms, some until the 17th–18th centuries. As a result of the [[Silesian Wars]], the region was annexed by the German state of [[Kingdom of Prussia|Prussia]] from [[Archduchy of Austria|Austria]] in 1742.

After [[World War I]], when the Poles and Czechs regained their independence, the easternmost part of Upper Silesia became again part of Poland by the decision of the [[Triple Entente|Entente Powers]] after [[Silesian Uprisings|insurrections by Poles]] and the [[Upper Silesian plebiscite]], while the [[Austrian Silesia|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 of World War II|Allies]] and became again part of Poland, although with a [[Soviet Union|Soviet]]-installed [[Polish People's Republic|communist regime]]. The small [[Lusatia]]n strip west of the [[Oder–Neisse line]], which had belonged to Silesia since 1815, became part of [[East Germany]].

As the result of the [[Flight and expulsion of Germans (1944–1950)|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 [[National costumes of Poland|costumes]]. There is ongoing debate about whether the [[Silesian language]], common in Upper Silesia, should be considered a dialect of [[Polish language|Polish]] or a separate language. The [[Lower Silesian language|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—{{langx|pl|Śląsk}} {{IPA|pl|ɕlɔ̃sk||Pl-Śląsk.ogg}}; {{langx|de|Schlesien}} {{IPA|de|ˈʃleːzi̯ən||De-Schlesien.ogg}}; {{langx|cs|Slezsko}} {{IPA|cs|ˈslɛsko|}}; {{langx|sli|Schläsing}}; {{langx|szl|Ślōnsk}} {{IPA|szl|ɕlonsk|}}; {{langx|dsb|Šlazyńska}} {{IPA|dsb|ˈʃlazɨnʲska|}}; {{langx|hsb|Šleska}} {{IPA|hsb|ˈʃlɛska|}}; {{langx|sk|Sliezsko}}; [[Latin]], Spanish and English: ''Silesia''; {{langx|fr|link=no|Silésie}}; {{langx|nl|Silezië}}; {{langx|it|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 languages|Pre-Indo-European]] topographic names in the region (see [[old European hydronymy]]).<ref>Zbigniew Babik, "Najstarsza warstwa nazewnicza na ziemiach polskich w granicach średniowiecznej Słowiańszczyzny", Uniwersitas, Kraków, 2001.</ref> According to some [[Polish language|Polonists]], the name ''Ślęża'' {{IPA|pl|ˈɕlɛ̃ʐa|}} or ''Ślęż'' {{IPA|pl|ɕlɛ̃ʂ|}} is directly related to the Old Polish words ''ślęg'' {{IPA|pl|ɕlɛŋk|}} or ''śląg'' {{IPA|pl|ɕlɔŋk|}}, which means dampness, moisture, or humidity.<ref>Rudolf Fischer. Onomastica slavogermanica. Uniwersytet Wrocławski. 2007. t. XXVI. 2007. str. 83</ref> They disagree with the hypothesis of an origin for the name ''Śląsk'' from the name of the [[Silingi|Silings]] tribe.<ref name='RGA'>{{cite encyclopedia |editor1=Jankuhn, Herbert |editor2=Beck, Heinrich | encyclopedia = [[Reallexikon der Germanischen Altertumskunde]] | title = Wandalen | language = de | edition = 2nd | year = 2006 | publisher = de Gruyter | volume = 33 | location = Berlin, Germany; New York City | quote = Da die Silingen offensichtlich ihren Namen im mittelalterlichen pagus silensis und dem mons slenz – möglicherweise mit dem Zobten gleichzusetzen [...] – hinterließen und damit einer ganzen Landschaft – Schlesien – den Namen gaben [...]|display-editors=etal}}</ref>{{Original research inline|date=December 2024}}

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.<ref>{{cite book|publisher= C.H.Beck|title=Deutsche und Polen: Geschichte, Kultur, Politik|author=Andreas Lawaty, Hubert Orłowski|year= 2003|page=183|language=de}}</ref>

==History==
{{Main|History of Silesia}}
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]].<ref>R. Żerelik(in:) M. Czpliński (red.) Historia Śląska, Wrocław 2007, pp. 34–35</ref>

[[Germanic peoples|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,<ref>R. Żerelik(in:) M. Czpliński (red.) Historia Śląska, Wrocław 2007, pp. 37–38</ref> 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 tribes|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)|Barycz]] River, north of which lived the [[Polans (western)|Western Polans]] tribe who gave [[Name of Poland|Poland its name]].<ref name="M. Czpliński 2007">R. Żerelik(in:) M. Czpliński (red.) Historia Śląska, Wrocław 2007, pp. 21–22</ref>

[[File:Polska 960 - 992.svg|thumb|Map of Poland with Silesia (''Śląsk'') in the year 992 during the rule of [[Mieszko I]]]]

The first known states in Silesia were [[Greater Moravia]] and [[Duchy of Bohemia|Bohemia]]. In the 10th century, the Polish ruler [[Mieszko I]] of the [[Piast dynasty]] incorporated Silesia into the newly established [[Duchy of Poland (c. 960–1025)|Polish state]]. In 1000, the [[Roman Catholic Archdiocese of Wrocław|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 [[Siege of Niemcza|Niemcza]] and in 1109 at [[Siege of Głogów|Głogów]]. During the [[History of Poland during the Piast dynasty|Fragmentation of Poland]], Silesia and the rest of the country were divided into [[Duchies of Silesia|many smaller duchies]] ruled by various [[Dukes of Silesia|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.<ref name="M. Czpliński 2007"/> 

[[File:Polska 1102 - 1138.png|thumb|left|Poland with Silesia during the rule of [[Bolesław III Wrymouth]], 1102-1138]]

[[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.<ref>{{cite magazine|last=Zientara|first=Benedykt|year=1975|title=Walonowie na Śląsku w XII i XIII wieku|magazine=Przegląd Historyczny|language=pl|issue=66/3|pages=353, 357}}</ref> Since the 13th century, [[Germanization|German cultural and ethnic influence]] increased as a result of [[Ostsiedlung|immigration from German-speaking states]] of the [[Holy Roman Empire]].

The first granting of [[town privileges|municipal privileges]] in Poland took place in the region, with the granting of rights for [[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, Lower Silesian Voivodeship|Henryków]] and Wrocław in Silesia, respectively.

[[File:Silesia 1172-1177.jpg|thumb|Silesia in the early period of [[Piast Poland#Fragmentation and Invasion, (1146-1295)|Poland's fragmentation]], 1172–1177, Lower Silesia with [[Lubusz Land]] in orange, Upper Silesia in green and yellow]]

In 1241, the [[Mongol Empire|Mongols]] conducted their [[First Mongol invasion of Poland|first invasion of Poland]], causing widespread panic and mass flight. They looted much of the region and defeated the combined Polish, Moravian and German forces led by Duke [[Henry II the Pious]] at the [[Battle of Legnica]], which took place at [[Legnickie Pole]] near the city of [[Legnica]]. Upon the death of [[Orda Khan]], the Mongols chose not to press forward further into Europe, but returned east to participate in the election of a new Grand Khan (leader).

Between 1289 and 1292, Bohemian king [[Wenceslaus II]] became ''[[suzerain]]'' of some of the [[Upper Silesia]]n duchies. Polish monarchs had not renounced their hereditary rights to Silesia until 1335.<ref>R. Żerelik(in:) M. Czpliński (red.) Historia Śląska, Wrocław 2007, p. 81</ref> The province became part of the [[Lands of the Bohemian Crown|Bohemian Crown]] which was part of the Holy Roman Empire; however, a number of duchies remained under the rule of the Polish dukes from the houses of Piast, [[Jagiellonian dynasty|Jagiellon]] and [[House of Sobieski|Sobieski]] as formal Bohemian [[fief]]doms, some until the 17th–18th centuries. In 1469, sovereignty over the region passed to [[Kingdom of Hungary|Hungary]], and in 1490, it returned to Bohemia. In 1526 Silesia passed with the Bohemian Crown to the [[Habsburg monarchy]].

In the 15th century, several changes were made to Silesia's borders. Parts of the territories that had been transferred to the Silesian Piasts in 1178 were bought by the [[Monarchs of Poland|Polish kings]] in the second half of the 15th century (the [[Duchy of Oświęcim]] in 1457; the [[Duchy of Zator]] in 1494). The Bytom area remained in the possession of the Silesian Piasts, though it was a part of the [[Diocese of Kraków]].<ref name="M. Czpliński 2007"/> The Duchy of [[Krosno Odrzańskie]] ({{lang|de|Crossen}}) was inherited by the [[Margraviate of Brandenburg]] in 1476 and with the renunciation of King [[Ferdinand I, Holy Roman Emperor|Ferdinand I]] and the estates of Bohemia in 1538, became an integral part of Brandenburg. From 1645 until 1666, the [[Duchy of Opole and Racibórz]] was held in pawn by the Polish [[House of Vasa]] as dowry of the Polish queen [[Cecilia Renata of Austria|Cecylia Renata]].

[[File:Crown of Bohemia 1648.png|thumb|[[Lands of the Bohemian Crown]] between 1635 and 1742, before most of Silesia was ceded to [[Kingdom of Prussia|Prussia]]]]

In 1742, most of Silesia was seized by King [[Frederick II of Prussia]] in the [[War of the Austrian Succession]], eventually becoming the Prussian [[Province of Silesia]] in 1815; consequently, Silesia became part of the [[German Empire]] when it was proclaimed in 1871. The Silesian capital Breslau became at that time one of the big cities in Germany. Breslau was a center of Jewish life in Germany and an important place of science (university) and industry (manufacturing of locomotives). German mass tourism started in the Silesian mountain region (Hirschberg, Schneekoppe). 

After World War I, a part of Silesia, [[Upper Silesia]], was contested by Germany and the newly independent [[Second Polish Republic]]. The [[League of Nations]] organized a [[Upper Silesia plebiscite|plebiscite]] to decide the issue in 1921. It resulted in 60% of votes being cast for Germany and 40% for Poland.<ref>[http://www.gonschior.de/weimar/Preussen/Oberschlesien/Volksentscheide.html gonschior.de] (in German)</ref> Following the third [[Silesian uprising]] (1921), however, the easternmost portion of Upper Silesia (including Katowice), with a majority ethnic Polish population, was awarded to Poland, becoming the [[Silesian Voivodeship (1920–1939)|Silesian Voivodeship]]. The Prussian Province of Silesia within Germany was then divided into the provinces of [[Province of Lower Silesia|Lower Silesia]] and [[Province of Upper Silesia|Upper Silesia]]. Meanwhile, [[Austrian Silesia]], the small portion of Silesia retained by Austria after the [[Silesian Wars]], was mostly awarded to the new Czechoslovakia (becoming known as Czech Silesia and [[Trans-Olza]]), although most of [[Cieszyn]] and territory to the east of it went to Poland.

Polish Silesia was among the first regions invaded during Germany's 1939 [[invasion of Poland|attack on Poland]], which started [[World War II]]. One of the claimed goals of [[Occupation of Poland (1939–1945)|Nazi German occupation]], particularly in Upper Silesia, was the extermination of those whom Nazis viewed as "[[Untermensch|subhuman]]", namely Jews and ethnic Poles. The Polish and Jewish population of the then Polish part of Silesia was subjected to genocide involving [[Expulsion of Poles by Nazi Germany|expulsions]], mass murder and deportation to [[Nazi concentration camps]] and [[Forced labour under German rule during World War II|forced labour]] camps, while Germans were settled in pursuit of {{lang|de|[[Lebensraum]]}}.<ref>Piotr Eberhardt, Political Migrations in Poland, 1939–1948, Warsaw 2006, p.25</ref> Two thousand Polish intellectuals, politicians, and businessmen were murdered in the {{lang|de|[[Intelligenzaktion|Intelligenzaktion Schlesien]]}}<ref>{{cite book|last=Wardzyńska|first=Maria|year=2009|title=Był rok 1939.

The [[Potsdam Conference]] of 1945 defined the [[Oder-Neisse line]] as the border between Germany and Poland, pending a final peace conference with Germany which eventually never took place.<ref>{{cite book|title=The Politics Today Companion to West European Politics|author=Geoffrey K.

However, they could not return, and those who had stayed were expelled and a new Polish population, including people displaced from [[Territories of Poland annexed by the Soviet Union|former Eastern Poland annexed by the Soviet Union]] and from Central Poland, joined the surviving native Polish inhabitants of the region. After 1945 and in 1946, nearly all of the 4.5&nbsp;million Silesians of German descent fled, or were interned in camps and expelled, including some thousand German Jews who survived the Holocaust and had returned to Silesia.
The newly formed [[Polish United Workers' Party]] created a [[Recovered Territories|Ministry of the Recovered Territories]] that claimed half of the available arable land for state-run collectivized farms. Many of the new Polish Silesians who resented the Germans for their invasion in 1939 and brutality in occupation now resented the newly formed Polish communist government for their population shifting and interference in agricultural and industrial affairs.<ref>{{cite book|last=Lukowski, Zawadski|first=Jerzy, Hubert|title=A Concise History of Poland|year=2006|publisher=Cambridge University Press|location=Cambridge, UK|isbn=978-0-521-61857-1|pages=[https://archive.org/details/concisehistoryof00luko/page/278 278–280]|url-access=registration|url=https://archive.org/details/concisehistoryof00luko/page/278}}</ref>

The administrative division of Silesia within Poland has changed several times since 1945. Since 1999, it has been divided between [[Lubusz Voivodeship]], [[Lower Silesian Voivodeship]], [[Opole Voivodeship]], and [[Silesian Voivodeship]]. Czech Silesia is now part of the Czech Republic, forming part of the [[Moravian-Silesian Region]] and the northern part of the [[Olomouc Region]]. Germany retains the Silesia-Lusatia region ({{lang|de|Niederschlesien-Oberlausitz}} or {{lang|de|Schlesische Oberlausitz}}) west of the [[Lusatian Neisse|Neisse]], which is part of the federal state of [[Saxony]].

The region was affected by the [[1997 Central European flood|1997]], [[2010 Central European floods|2010]] and [[2024 Central European floods|2024]] Central European floods.

==Geography==
[[File:Landkarte von Schlesien.jpg|thumb|First map of Silesia by [[Martin Helwig]], 1561; north at the bottom]]
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 River|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 (river)|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 ({{lang|pl|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 ({{lang|pl|województwo śląskie}}) for the province covering this area. In fact, the word {{lang|pl|Śląsk}} in Polish (when used without qualification) now commonly refers exclusively to this area (also called {{lang|pl|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 [[History of Poland (1945–1989)|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.<ref name="en.poland.gov.pl">{{cite web|url=http://en.poland.gov.pl/Natural,Resources,310.html |title=Natural Resources &#124; poland.gov.pl |publisher=En.poland.gov.pl |access-date=19 November 2013}}</ref> Coal mining declined during the next two decades, but has increased again following the end of Communist rule.

[[File:KWK Bolesław Śmiały 01.jpg|thumb|upright|[[Bolesław Śmiały Coal Mine]], [[Łaziska Górne]]]]

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 {{Convert|4,500|km2|mi2|abbr=on}}.<ref name="en.poland.gov.pl"/> Deposits in Lower Silesia have proven to be difficult to exploit and the area's unprofitable mines were closed in 2000.<ref name="en.poland.gov.pl"/> In 2008, an estimated 35&nbsp;billion tonnes of [[lignite]] reserves were found near Legnica, making them some of the largest in the world.<ref>{{cite web|url=http://www.gazetawyborcza.pl/1,82244,4820533.html |title=Mamy największe złoża węgla brunatnego na świecie |language=pl |publisher=Gazetawyborcza.pl |access-date=20 November 2013}}</ref>

From the fourth century BC, iron ore has been mined in the upland areas of Silesia.<ref name="en.poland.gov.pl"/> The same period had lead, copper, silver, and gold mining. Zinc, cadmium, arsenic,<ref>S.Z. Mikulski, "Late-Hercynian gold-bearing arsenic-polymetallic mineralization within Saxothuringian zone in the Polish Sudetes, Northeast Bohemian Massif".

Lower Silesia features large copper mining and processing between the cities of [[Legnica]], [[Głogów]], [[Lubin]], and [[Polkowice]]. In the Middle Ages, gold ({{langx|pl|link=no|złoto}}) and silver ({{langx|pl|link=no|srebro}}) were mined in the region, which is reflected in the names of the former mining towns of [[Złotoryja]], [[Złoty Stok]] and [[Srebrna Góra, Lower Silesian Voivodeship|Srebrna Góra]].

The region is known for stone quarrying to produce limestone, [[marl]], marble, and basalt.<ref name="en.poland.gov.pl"/>

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.<ref>{{cite web|url=http://umwo.opole.pl/serwis/index.php?id=2009 |title=Samorząd Województwa Opolskiego |publisher=Umwo.opole.pl |access-date=20 November 2013}}</ref>

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.<ref>{{Cite book|url=https://archive.org/stream/dictionaryofrace00unitrich#page/128/mode/1up/search/Silesian|title=Dictionary of Races or Peoples|last1=Dillingham|first1=William Paul|last2=Folkmar|first2=Daniel|last3=Folkmar|first3=Elnora|publisher=Washington, Government Printing Office|year=1911|location=Washington, D.C.|pages=128}}</ref><ref name=":1">{{Cite book|url=https://archive.org/stream/dictionaryofrace00unitrich#page/105/mode/1up|title=Dictionary of Races or Peoples|last1=Dillingham|first1=William Paul|last2=Folkmar|first2=Daniel|last3=Folkmar|first3=Elnora|publisher=Washington, Government Printing Office|others=United States.

====Ethnicity====
Modern Silesia is inhabited by [[Polish people|Poles]], [[Silesians]], [[ethnic Germans|Germans]], and [[Czechs]]. Germans first came to Silesia during the [[Late Middle Ages|Late Medieval]] [[Ostsiedlung]].<ref>{{Cite book|url=https://archive.org/details/bub_gb_CqpCAAAAIAAJ|title=Die Verbreitung und die Herkunft der Deutschen in Schlesien|last=Weinhold|first=Karl|publisher=J. Engelhorn|year=1887|location=Stuttgart|language=de|trans-title=The Spread and the Origin of Germans in Silesia}}</ref> 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 (ethnic group)|Moravians]], Silesians, and [[Polish minority in the Czech Republic|Poles]].

In the early 19th century the population of the [[Province of Silesia|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]].<ref name="Gumpert">{{cite book|title=Polen, Deutschland|author=Jobst Gumpert|publisher=Callwey |year= 1966|pages=138|language = de}}</ref> 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.<ref>Hunt Tooley, T (1997). ''National Identity and Weimar Germany: Upper Silesia and the Eastern Border, 1918–1922,'' University of Nebraska Press, p.17.</ref>

The [[Austrian Silesia|Austrian part of Silesia]] had a mixed German, Polish and Czech population, with Polish-speakers forming a majority in [[Cieszyn Silesia]].<ref>{{Cite book|title=Geschichte des deutsch-slawischen Sprachkontaktes im Teschener Schlesien|last=Chromik|first=Grzegorz|isbn=978-3-88246-398-9|pages=258–322|language=de}}</ref>

====Religion====
[[File:Verbreitung der Konfessionen im deutschen Reich.jpg|thumb|upright=1.5|Confessions in the German Empire (Protestant/Catholic; c. 1890). Lower Silesia was mostly Protestant, while Glatz ([[Kłodzko]]) and Upper Silesia were mostly Catholic.]]
Historically, Silesia was about equally split between [[Protestants]] (overwhelmingly [[Lutherans]]) and [[Roman Catholics]]. In an 1890 census taken in the German part, Roman Catholics made up a slight majority of 53%, while the remaining 47% were almost entirely Lutheran.<ref>[[Meyers Konversations-Lexikon|Meyers Konversationslexikon]] 5. Auflage</ref> Geographically speaking, Lower Silesia was mostly Lutheran except for the [[Kłodzko Land|Glatzer Land]] (now [[Kłodzko County]]). Upper Silesia was mostly Roman Catholic except for some of its northwestern parts, which were predominantly Lutheran. Generally speaking, the population was mostly Protestant in the western parts, and it tended to be more Roman 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, [[Flight and expulsion of Germans|were forcibly expelled]]. Poles, who were mostly Roman Catholic, were resettled in their place. Today, Silesia remains predominantly Roman Catholic.

The majority of Germans fled or were expelled from the present-day Polish and Czech parts of Silesia during and after World War II. From June 1945 to January 1947, 1.77&nbsp;million Germans were expelled from Lower Silesia, and 310,000 from Upper Silesia.<ref>DB Klusmeyer & DG Papademetriou (2009).

One of its most notable but controversial spokesmen was the [[Christian Democratic Union (Germany)|Christian Democratic Union]] politician [[Herbert Hupka]].

The expulsion of Germans led to widespread underpopulation. The population of the town of [[Głogów]] fell from 33,500 to 5,000, and from 1939 to 1966 the population of Wrocław fell by 25%.<ref>Scholz, A (1964).

''Dark Continent: Europe's 20th Century,'' Penguin, p.223.</ref> and Silesia's population did not reach pre-war levels until the late 1970s. The Polish settlers who repopulated Silesia were partly from the former Polish [[Kresy|Eastern Borderlands]], which was annexed by the [[Soviet Union]] in 1939. Wrocław was partly repopulated with refugees from the formerly Polish city of [[Lviv|Lwów]].
