Lower Silesia

Lower Silesia ( ; ; ; ; ; ; ; ) is a historical and geographical region mostly located in Poland with small portions in the Czech Republic and Germany. It is the western part of the region of Silesia. Its largest city is Wrocław.

The first state to have a stable hold over the territory of what will be considered Lower Silesia was the short-lived Great Moravia in the 9th century. Afterwards, in the Middle Ages, Lower Silesia was part of Piast-ruled Poland. It was one of the leading regions of Poland, and its capital Wrocław was one of the main cities of the Polish Kingdom. Lower Silesia emerged as a distinctive region during the fragmentation of Poland in 1172, when the Duchies of Opole and Racibórz, considered Upper Silesia since, were formed of the eastern part of the Duchy of Silesia, and the remaining, western part was since considered Lower Silesia. During the , German settlers were invited to settle in the region, which until then had a Polish majority. As a result, the region became largely Germanised in the following centuries. Nonetheless, it remained a pioneering center of Polish culture, where the oldest Polish writing and first Polish print were created, and the first town rights were granted.

In the Late Middle Ages the region fell under the overlordship of the Bohemian Crown, but large parts remained under the rule of local Polish dukes of the Piast, Jagiellonian and Sobieski dynasties, some up to the 17th and 18th century. Briefly under the suzerainty of the Kingdom of Hungary, it fell to the Austrian Habsburg monarchy in 1526.

In 1742, Austria ceded nearly all of Lower Silesia to the Kingdom of Prussia in the Treaty of Berlin, except for the southern part of the Duchy of Neisse. Within the Prussian kingdom, the region became part of the Province of Silesia. In 1871, the Prussian-controlled portion of Lower Silesia was integrated into the German Empire. After World War I, Lower Silesia was divided, as small parts were reintegrated with Poland and Czechoslovakia, which both regained independence. In the interbellum, the Polish population of the region was persecuted in the German-controlled part of the region.

After Germany's defeat in World War II in 1945, most of the region became once again part of Poland, while a smaller part west of the Oder-Neisse line became part of East Germany and Czech Lower Silesia (Jesenicko and Opavsko regions) remained as a part of Czechoslovakia. By 1949, almost the entire pre-war German population was expelled in accordance with the Potsdam Agreement. Poles displaced from the former Polish lands incorporated into the USSR settled in Lower Silesia after the war, as well as Polish settlers from other parts of Poland.

The region is known for an abundance of historic architecture of various styles, including many castles and palaces, well preserved or reconstructed old towns, numerous spa towns, and historic burial sites of Polish monarchs and consorts (in Wrocław, Legnica and Trzebnica). Provided by Wikipedia
