It was created in 1572 out of the Duchy of Cieszyn as vassal of Bohemia and sold by Wenceslaus III Adam, Duke of Cieszyn to Charles Promnitz. Lately, in 1582 was sold to Adam Schaffgotsch, but ten years later was sold again to Sunnegh family. They in 1724 sold state country to Henry of Salm. In 1743 was county owned by Count Friedrich Wilhelm von Haugwitz and in 1751 its status was changed to status maiores, so it can send deputies to Silesian Assembly. In 1752, the State Country (Status Maiores) of Bielsko was purchased by Aleksander Józef Sulkowski. In that same year, the State Country was changed to the status of a lower principality (Fürstentum). On November 2, 1754, Queen Maria Theresa of Austria created the Principality of Bielsko (Herzogtum Bielitz). The next owners of the Principality of Bielsko had the right to the title of Herzog (Duke), during which time the remaining members of the family counted themselves amongst the lesser noble status of Fürst (Prince). The Principality was till 1849 as autonomous principality in Austrian Silesia. After the 1920 division of Cieszyn Silesia between Poland and Czechoslovakia it became a part of Poland. Its capital was in Bielsko, dukes were vassals of the King of Bohemia.

Bielsko-Biała (Polish: [ˈbjɛlskɔ ˈbjawa] ; Czech: Bílsko-Bělá; German: Bielitz-Biala, Silesian: Biylsko-Biołŏ; Wymysorys: Byłc-Bejł) is a city in southern Poland, with a population of approximately 166,765 as of December 2022, making it the 22nd largest city in Poland, and an area of 124.51 km2 (48.07 sq mi). It is the core of the broader metropolitan area with around 335,000 inhabitants. It serves as the seat of the Bielsko County, Euroregion Beskydy, Roman Catholic Diocese of Bielsko–Żywiec and the Evangelical Church Diocese of Cieszyn. Situated north of the Beskid Mountains, Bielsko-Biała is composed of two former towns which merged in 1951—Bielsko in the west and Biała in the east—on opposite banks of the Biała River that once divided Silesia and Lesser Poland. The history of Bielsko dates back to the 13th century, while Biała was founded in the 16th century and obtained city rights in 1723. Despite the administrative separation, both towns effectively functioned as one urban area already in the 19th century. Industrialization, especially the textile and automotive industries, was of great importance for its development in the past. Between 1975 and 1998, the city was the seat of Bielsko-Biała Voivodeship and currently lies within the Silesian Voivodeship. Bielsko-Biała is the administrative, economic, academic and cultural centre for the Silesian-Lesser Polish border region, sometimes colloquially referred to as Podbeskidzie. It is also an important commercial and industrial hub, as well as a road and railway junction. It is a significant tourist destination due to its numerous architectural monuments (a popular slogan Little Vienna refers to many Revivalist and Art Nouveau buildings shaping the cityscape of the central districts) and its direct proximity to the mountains (fourteen mountain peaks lie within the city limits).
