Duchy of Opole in the context of "Sigismund Báthory"

Lower Silesia (Polish: Dolny Śląsk [ˈdɔlnɨ ˈɕlɔ̃sk]; Czech: Dolní Slezsko; German: Niederschlesien [ˈniːdɐˌʃleːzi̯ən] ; Silesian: Dolny Ślōnsk; Upper Sorbian: Delnja Šleska [ˈdɛlnʲa ˈʃlɛska]; Lower Sorbian: Dolna Šlazyńska [ˈdɔlna ˈʃlazɨnʲska]; Lower Silesian: Niederschläsing; Latin: Silesia Inferior) 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. The oldest Polish writing and first Polish print were created in the region. During the Ostsiedlung, the Piast rulers invited German settlers to settle in the region, which until then had a Polish majority. As a result, the region became largely German-speaking by the end of the 15th century.

Opole (Polish: [ɔˈpɔlɛ] ; German: Oppeln; Silesian: Ôpole; Silesian German: Uppeln) is a city located in southern Poland on the Oder River and the historical capital of Upper Silesia. With a population of approximately 127,387 as of the 2021 census, it is the capital of Opole Voivodeship (province) and the seat of Opole County. Its metropolitan area was home to 146,522 inhabitants. It is the largest city in its province.

Its history dates to the 8th century, and Opole is one of the oldest cities in Poland. An important stronghold in Poland, it became a capital of a duchy within medieval Poland in 1172, and in 1217 it was granted city rights by Duke Casimir I of Opole, the great-grandson of Polish Duke Bolesław III Wrymouth. During the Medieval Period and the Renaissance, the city was known as a centre of commerce; several main trade routes intersected here, which helped to generate steady profits from transit trade. The rapid development of the town was also caused by the establishment of a seat of regency in Opole in 1816. The first railway connection between Opole, Brzeg and Wrocław was opened in 1843 and the first manufacturing plants were constructed in 1859, which greatly contributed to the city's regional significance.
