Polonists, the name ''Ślęża'' or ''Ślęż'' is directly related to the Old Polish words ''ślęg'' or ''śląg'' , which means dampness, moisture, or humidity. They disagree with the hypothesis of an origin for the name ''Śląsk'' from the name of the

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 until 1945–48.

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 .
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 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.
Ethnicity
Modern Silesia is inhabited by Poles, Silesians, ethnic Germans, Germans, and Czechs. Germans first came to Silesia during the Late Middle Ages, 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 (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.
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 Silesia, Austrian part of Silesia had a mixed German, Polish and Czech population, with Polish-speakers forming a majority in Cieszyn Silesia.
Religion

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. 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.
Existing since the 12th century, Silesia's Jewish community was concentrated around Wrocław and Upper Silesia, and numbered 48,003 (1.1% of the population) in 1890, decreasing to 44,985 persons (0.9%) by 1910. In Polish East Upper Silesia, the number of Jews was around 90,000–100,000. Historically the community had suffered a number of localised expulsions such as their 1453 expulsion from
Wrocław. From 1712 to 1820 a succession of men held the title Chief Rabbi of Silesia ("Landesrabbiner"): Naphtali ha-Kohen (1712–16); Samuel ben Naphtali (1716–22); Ḥayyim Jonah Te'omim (1722–1727); Baruch b. Reuben Gomperz (1733–54); Joseph Jonas Fränkel (1754–93); Jeremiah Löw Berliner (1793–99); Lewin Saul Fränkel (1800–7); Aaron Karfunkel (1807–16); and Abraham ben Gedaliah Tiktin (1816–20).
Consequences of World War II
After the German invasion of Poland in 1939, following Racial policy of Nazi Germany, Nazi racial policy, the Jewish population of Silesia was subjected to Nazi genocide with executions performed by Einsatzgruppe z. B.V. led by Udo von Woyrsch and Einsatzgruppe I led by Bruno Streckenbach, imprisonment in ghettos and ethnic cleansing to the General Government. In their efforts to exterminate the Jews through murder and ethnic cleansing Nazi established in Silesia province the Auschwitz and Gross-Rosen camps. Expulsions were carried out openly and reported in the local press.
[Steinbacher, S. "In the Shadow of Auschwitz, The murder of the Jews of East Upper Silesia", in Cesarani, D. (2004) ''Holocaust: From the persecution of the Jews to mass murder,'' Routledge, P126] Those sent to ghettos would from 1942 be expelled to concentration and work camps.
[Steinbacher, S. "In the Shadow of Auschwitz, The murder of the Jews of East Upper Silesia", in Cesarani, D. (2004) ''Holocaust: From the persecution of the Jews to mass murder,'' Routledge, pp.110–138.] Between 5 May and 17 June, 20,000 Silesian Jews were sent to Birkenau to gas chambers and during August 1942, 10,000 to 13,000 Silesian Jews were murdered by gassing at Auschwitz. Most Jews in Silesia were exterminated by the Nazis. After the war Silesia became a major centre for repatriation of the Jewish population in Poland which survived Nazi German extermination and in autumn 1945, 15,000 Jews were in Lower Silesia, mostly Polish Jews returned from territories now belonging to Soviet Union, rising in 1946 to seventy thousand as Jewish survivors from other regions in Poland were relocated.
[Kochavi, AJ (2001). ''Post-Holocaust politics: Britain, the United States & Jewish refugees, 1945–1948,'' University of North Carolina Press, p.176.]
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 million Germans were expelled from Lower Silesia, and 310,000 from Upper Silesia. Today, most German Silesians and their descendants live in the territory of the Federal Republic of Germany, many of them in the Ruhr area working as miners, like their ancestors in Silesia. To smooth their integration into West German society after 1945, they were placed into officially recognized organizations, like the Landsmannschaft Schlesien, with financing from the federal West German budget. 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

fell from 33,500 to 5,000, and from 1939 to 1966 the population of Wrocław fell by 25%. Attempts to repopulate Silesia proved unsuccessful in the 1940s and 1950s, 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.
