Lower Silesia in the context of "Ostsiedlung"

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.

Wrocław (Polish: [ˈvrɔt͡swaf] ; German: Breslau [ˈbʁɛslaʊ] ; also known by other names) is a city in southwestern Poland, and the capital of the Lower Silesian Voivodeship. It is the largest city and historical capital of the region of Silesia. It lies on the banks of the Oder River in the Silesian Lowlands of Central Europe, roughly 40 kilometres (25 mi) to the north of the Sudetic Mountains. In 2023, the official population of Wrocław was 674,132, making it the third-largest city in Poland. The population of the Wrocław metropolitan area is around 1.25 million.

Wrocław is the historical capital of Silesia and Lower Silesia. The history of the city dates back over 1,000 years; throughout history it has been part of, chronologically: the Duchy of Poland, the Kingdom of Poland, the Duchy of Silesia, the Kingdom of Bohemia, the Kingdom of Hungary, the Habsburg monarchy of Austria, the Kingdom of Prussia and Germany, until it became again part of Poland in 1945 immediately after World War II.

The Kłodzko Valley (Polish: Kotlina Kłodzka, Czech: Kladská kotlina, German: Glatzer Kessel) a valley in the Sudetes mountain range, that covers the central part of Kłodzko County in south-western Poland, with the southern tip extending to the Czech Republic around the town of Králíky. The chief and largest town in the valley is Kłodzko.

It is traversed by the upper Eastern Neisse river running from south to north and surrounded by the Table Mountains, Bardzkie Mountains and Bystrzyckie Mountains of the Central Sudetes in the west as well as by the Snieznik Mountains, Golden Mountains and Owl Mountains of the Eastern Sudetes in the east. The mountain passes of Kudowa/Běloves in the west and of Międzylesie/Lichkov in the south connect to Czech areas around Náchod and Králíky respectively. Flowing through the valley, the Eastern Neisse is joined by Biała Lądecka [pl], Bystrzyca Dusznicka [pl] and Ścinawka rivers, and then exits it in the northeast through the Bardzkie Mountains to Bardo in Lower Silesia.

The Ślęza (Polish: [ˈɕlɛ̃za]; German: Lohe) is a 78.6 km river in Lower Silesia, southern Poland, a left tributary of the Oder. It starts in the Niemcza Hills (Polish: Wzgórza Niemczańskie), part of the Sudeten Foreland (Przedgórze Sudeckie), and flows near Mount Ślęża through the Silesian Lowland (Nizina Śląska) and enters the Oder in Wrocław.

The most important tributary is the Mała Ślęza ("Small Ślęza"). The most important towns on the river are: Niemcza, Tyniec nad Ślęzą, Jordanów Śląski and Wrocław.

The former eastern territories of Germany (German: ehemalige deutsche Ostgebiete) refer to those territories east of the current eastern border of Germany, i.e. the Oder–Neisse line, which historically had been considered German and which were annexed by Poland and the Soviet Union after World War II. In contrast to the lands awarded to the restored Polish state by the Treaty of Versailles after World War I, the German territories lost with the post-World War II Potsdam Agreement were either almost exclusively inhabited by Germans before 1945 (the bulk of East Prussia, Lower Silesia, Farther Pomerania, and parts of Western Pomerania, Lusatia, and Neumark), mixed German–Polish with a German majority (the Posen–West Prussia Border March, Lauenburg and Bütow Land, the southern and western rim of East Prussia, Ermland, Western Upper Silesia, and the part of Lower Silesia east of the Oder), or mixed German–Czech with a German majority (Glatz). Virtually the entire German population of the territories that did not flee voluntarily in the face of the Red Army advance of 1945, was violently expelled to Germany, with their possessions being forcibly expropriated.

The ceding of the east German lands to Poland was done in large part to compensate Poland for losing the Kresy lands east of the Curzon line, a region that was annexed by the Soviet Union after the German invasion of Poland in 1939. This territory had large populations of Ukrainians, Belarusians and Lithuanians – the main ethnic groups of three of the western republics of the Soviet Union – and many towns that were primarily inhabited by Poles and Jews. The Jewish communities in this region were mostly exterminated in the Holocaust and the Polish communities were mostly expelled to the restored Polish state after World War II, the communist-ruled Polish People's Republic. Poles from the northern part of Kresy were primarily resettled in Pomerania and Poles from Galicia were primarily resettled in Silesia, e.g. the Ossolineum and the Jan Kazimierz University in Lwów were both relocated to Wrocław, the former Breslau.

Lubusz Land (Polish: Ziemia lubuska; German: Land Lebus) is a historical region and cultural landscape in Poland and Germany on both sides of the Oder river.

Originally the settlement area of the Lechites, the swampy area was located east of Brandenburg and west of Greater Poland, south of Pomerania and north of Lower Silesia and Lower Lusatia. Presently its eastern part lies within the Polish Lubusz Voivodeship, the western part with its historical capital Lebus (Lubusz) in the German state of Brandenburg.

Kłodzko ([ˈkwɔt͡skɔ] ; Czech: Kladsko; German: Glatz; Latin: Glacio) is a historic town in south-western Poland, in the region of Lower Silesia. It is situated in the centre of the Kłodzko Valley, on the Eastern Neisse (Nysa Kłodzka) river.

Kłodzko is the seat of Kłodzko County (and of the rural Gmina Kłodzko, although the town itself is a separate urban gmina), and is situated in Lower Silesian Voivodeship. With 25,717 inhabitants at the 2021 Census, Kłodzko is the main commercial centre as well as an important transport and tourist node for the area.

The Book of Henryków (Polish: Księga henrykowska, Latin: Liber fundationis claustri Sanctae Mariae Virginis in Heinrichow) is a Latin chronicle of the Cistercian abbey in Henryków in Lower Silesia, Poland. Originally created as a registry of belongings looted during the first Mongol invasion of Poland of 1241, with time it was extended to include the history of the monastery. It is notable as the earliest document to include a sentence written entirely in what can be interpreted as an Old Polish language. Currently the book is on exhibition in the Archdiocesan Museum in Wrocław. On October 9, 2015 the Book of Henryków was entered in the list of UNESCO's "Memory of the World."

The first part of the 100-page-long book is devoted to the early history of the abbey, from its foundation by Henry the Bearded in 1227 until 1259. The second part includes the later history until 1310. In the record for 1270, a settler from the nearby village is reported to have said to his wife "Day, ut ia pobrusa, a ti poziwai." which could be roughly translated as "Let me, I shall grind, and you take a rest."
