Upper Silesia ( ; ;This is two leading ways of writing of Silesian alphabet, e.i. used on Silesian Wikipedia and various Silesian websites: https://www.wachtyrz.eu/ , https://silling.org . ; ; Silesian German: ; ) is the southeastern part of the historical and geographical region of Silesia, located today mostly in Poland, with small parts in the Czech Republic. The area is predominantly known for its heavy industry (mining and metallurgy).
Geography Upper Silesia is situated on the upper Oder River, north of the Eastern Sudetes mountain range and the Moravian Gate, which form the southern border with the historic Moravia region. Within the adjacent Silesian Beskids to the east, the Vistula River rises and turns eastwards, the Biała and Przemsza tributaries mark the eastern border with Lesser Poland. In the north, Upper Silesia borders on Greater Poland, and in the west on the Lower Silesian lands (the adjacent region around Wrocław also referred to as Middle Silesia).
It is currently split into a larger Polish and the smaller Czech Silesian part, which is located within the Czech regions of Moravia-Silesia and Olomouc. The Polish Upper Silesian territory covers most of the Opole Voivodeship, except for the Lower Silesian counties of Brzeg and Namysłów, and the western half of the Silesian Voivodeship (except for the Lesser Polish counties of Będzin, Bielsko-Biała, Częstochowa with the city of Częstochowa, Kłobuck, Myszków, Zawiercie and Żywiec, as well as the cities of Dąbrowa Górnicza, Jaworzno and Sosnowiec).
Divided Cieszyn Silesia as well as former Austrian Silesia are historical parts of Upper Silesia.
History
According to the 9th century Bavarian Geographer, the West Slavic Opolanie tribe had settled on the upper Oder River since the days of the Migration Period, centered on the gord of Opole. It is possible that during the times of Prince Svatopluk I (871–894), Silesia was a part of his Great Moravian realm. Upon its dissolution after 906, the region fell under the influence of the Přemyslid rulers of Bohemia, Duke Spytihněv I (894–915) and his brother Vratislaus I (915–921), possibly the founder and name giver of the Silesian capital Wrocław ().
Polish rule By 990 the newly installed Piast duke Mieszko I of the Polans had conquered large parts of Silesia. From the Middle Silesia fortress of Niemcza, his son and successor Bolesław I the Brave (992–1025), having established the Diocese of Wrocław, subdued the Upper Silesian lands of the pagan Opolanie, which for several hundred years were part of Poland, though contested by Bohemian dukes like Bretislaus I, who from 1025 invaded Silesia several times. Finally, in 1137, the Polish prince Bolesław III Wrymouth (1107–1138) came to terms with Duke Soběslav I of Bohemia, when a peace was made confirming the border along the Sudetes.
However, this arrangement fell apart when upon the death of Bolesław III and his testament the fragmentation of Poland began, which decisively enfeebled its central authority. The newly established Duchy of Silesia became the ancestral homeland of the Silesian Piasts, descendants of Bolesław's eldest son Władysław II the Exile, who nevertheless saw themselves barred from the succession to the Polish throne and only were able to regain their Silesian home territory with the aid of the Holy Roman Emperor.
The failure of the Agnatic seniority principle of inheritance also led to the split-up of the Silesian province itself: in 1172 Władysław's second son Mieszko IV Tanglefoot claimed his rights and received the Upper Silesian Duchy of Racibórz as an allodium from the hands of his elder brother Duke Bolesław I the Tall of Silesia. In the struggle around the Polish throne, Mieszko additionally received the former Lesser Polish lands of Bytom, Oświęcim, Zator, Siewierz and Pszczyna from the new Polish High Duke Casimir II the Just in 1177. When in 1202 Mieszko Tanglefoot had annexed the Duchy of Opole of his deceased nephew Jarosław, he ruled over all Upper Silesia as Duke of Opole and Racibórz.
In the early 13th century the ties of the Silesian Piasts with the neighbouring Holy Roman Empire grew stronger as several dukes married scions of German nobility. Promoted by the Lower Silesian Duke Henry I the Bearded, from 1230 also regent over Upper Silesia for the minor sons of his late cousin Duke Casimir I of Opole, large parts of the Silesian lands were settled with German immigrants in the course of the Ostsiedlung, establishing numerous cities according to German town law. The plans to re-unify Silesia shattered upon the first Mongol invasion of Poland and the death of Duke Henry II the Pious at the 1241 Battle of Legnica. Upper Silesia further fragmented upon the death of Duke Władysław Opolski in 1281 into the duchies of Bytom, Opole, Racibórz and Cieszyn. About 1269 the Duchy of Opava was established on adjacent Moravian territory, ruled by the Přemyslid duke Nicholas I, whose descendants inherited the Duchy of Racibórz in 1336. As they ruled both duchies in personal union, Opava grew into the Upper Silesian territory.
Bohemia, Hungary, Austria and Prussia In 1327 the Upper Silesian dukes, like most of their Lower Silesian cousins, had sworn allegiance to King John of Bohemia, thereby becoming vassals of the Bohemian kingdom. During the re-establishment of Poland under King Casimir III the Great, all Silesia was specifically excluded as non-Polish land by the 1335 Treaty of Trentschin becoming a land of the Bohemian Crown and — indirectly — of the Holy Roman Empire. By the mid-14th century, the influx of German settlers into Upper Silesia was stopped by the Black Death pandemic. Unlike in Lower Silesia, the Germanization process was halted; still a majority of the population spoke Polish and Silesian as their native language, often together with German (Silesian German) as a second language. In the southernmost areas, also Lach dialects were spoken. While Latin, Czech and German language were used as official languages in towns and cities, only in the 1550s (during the Protestant Reformation) did records with Polish names start to appear.
Upper Silesia was hit by the Hussite Wars and in 1469 was conquered by King Matthias Corvinus of Hungary, while the Duchies of Oświęcim and Zator fell back to the Polish Crown as a part of Lesser Poland. Upon the death of the Jagiellonian king Louis II in 1526, the Bohemian crown lands were inherited by the Austrian House of Habsburg. In the 16th century, large parts of Silesia had turned Protestant, promoted by reformers like Caspar Schwenckfeld. After the 1620 Battle of White Mountain, the Catholic Emperors of the Habsburg dynasty forcibly re-introduced Catholicism, led by the Jesuits.
Lower Silesia and most of Upper Silesia were occupied by the Kingdom of Prussia in 1742 during the First Silesian War and annexed by the terms of the Treaty of Breslau. A small part south of the Opava River remained within the Habsburg-ruled Bohemian Crown as the "Duchy of Upper and Lower Silesia", colloquially called Austrian Silesia. Incorporated into the Prussian Silesia Province from 1815, Upper Silesia became an industrial area taking advantage of its plentiful coal and iron ore. Prussian Upper Silesia became a part of the German Empire in 1871.
Ethnolinguistic structure before the plebiscite
The earliest exact census figures on ethnolinguistic or national structure (Nationalverschiedenheit) of the Prussian part of Upper Silesia, come from year 1819. The last pre-WW1 general census figures available, are from 1910 (if not including the 1911 census of school children - Sprachzählung unter den Schulkindern - which revealed a higher percent of Polish-speakers among school children than the 1910 census among the general populace). Figures (Table 1.) show that large demographic changes took place between 1819 and 1910, with the region's total population quadrupling, the percent of German-speakers increasing significantly, and that of Polish-speakers declining considerably. Also, the total land area in which Polish language was spoken, as well as the land area in which it was spoken by the majority, declined between 1790 and 1890. Polish authors before 1918 estimated the number of Poles in Prussian Upper Silesia as slightly higher than according to official German censuses.

United States Immigration Commission in 1911 classified Polish-speaking Silesians as Poles.
Interbellum, World War II, and post-war period
In 1919, after World War I, Polish miners organized large protests in Mysłowice. On August 15, 1919, the German Grenzschutz opened fire on protesting Polish miners and their families, killing seven miners, two women and a 13-year-old boy. The event, known as the "Mysłowice massacre", sparked the First Silesian Uprising against Germany.
Soon afterwards, the eastern part of Upper Silesia (with a majority of ethnic Poles) came under Polish rule as the Silesian Voivodeship, while the mostly German-speaking western part remained part of the Weimar Republic as the newly established Upper Silesia Province. In early 1919, the Polish–Czechoslovak War broke out around Cieszyn Silesia, whereafter Czechoslovakia gained the Trans-Olza strip in addition to the Hlučín Region.
From 1919 to 1921 three Silesian Uprisings occurred among the Polish-speaking populace of Upper Silesia; the Battle of Annaberg was fought in the region in 1921. In the Upper Silesia plebiscite of March 1921, a majority of 59.4% voted against merging with Poland and a minority of 40.6% voted for, with clear lines dividing Polish and German communities. The plan to divide the region was suggested by the Inter-Allied Commission on Upper Silesia, headed by the French general Henri Le Rond. The plan was decided by an ambassadors conference in Paris on 20 October 1921. The exact border, the maintenance of cross-border railway traffic and other necessary co-operations, as well as equal rights for all inhabitants in both parts of Upper Silesia, were all fixed by the German-Polish Accord on East Silesia, signed in Geneva on 15 May 1922. On 20 June 1922 the Weimar Republic ceded the East Upper Silesia region to Poland. The area became part of Silesian Voivodeship of the Second Polish Republic.
The new border only partly followed the results of the referendum. The reason was that closely following the local majority vote would have resulted in a plurality of enclaves and would thus not have been a viable border. Particularly in the Upper Silesian Industrial Region, the border line was often bizarre, cutting right through settlements or through industrial facilities.
