The Brynica has historically served as a boundary between Silesia and Lesser Poland. In 1443 it marked the border between the Siewierz Duchy, purchased by Kraków bishop Zbigniew Oleà Ânicki, and the Cieszyn Duchy under the Kingdom of Bohemia. During the Silesian Wars (1740âÂÂ1763), the course of the Brynica defined the state border between the Kingdom of Prussia and the Siewierz Duchy, which in 1790 was incorporated into the PolishâÂÂLithuanian Commonwealth, later forming part of the Duchy of Warsaw (1807âÂÂ1815) and then annexed by the Russian Empire following the Congress of Vienna in 1815. Between 1918 and 1922, it served as part of the PolishâÂÂGerman border. After the Silesian Uprisings, on 20 June 1922, in accordance with the provisions of the Geneva Convention on Upper Silesia of 15 May 1922, Polish troops under General Stanisà Âaw Szeptycki crossed the bridge over the Brynica between Szopienice and Sosnowiec, assuming control over the eastern part of Upper Silesia under Polish administration. One of the insurgents, Janusz Howaniec, symbolically broke the chains of subjugationâÂÂa moment commemorated by a plaque at the site.
