チェシン公国
The part of the villages on the left bank of the Biała continued to be a part of the Duchy of Teschen, which like the Duchy of Oświęcim in 1327 also became a fee of the Kingdom of Bohemia. However, when the Duchy of Oświęcim became a part of Poland in the 1450s, the Duchy of Teschen continued to be a part of the Kingdom of Bohemia, which itself became a part of the Habsburg Monarchy in 1526.
