拉瓦省
It is not known when Biala Rawska received town charter, but it happened before 1498. At that time, the town was property of Bishops of Chelm, and was an important administrative center, seat of Biala County of Rawa Voivodeship. Located along busy merchant trails to Mazovian Czersk, Leczyca and Sandomierz, Biala prospered. Good times ended in the 1650s, during the disastrous Swedish invasion of Poland, after which the population of Biala was reduced to only 100 people. The town never recovered from Swedish destruction: in 1777, its population was only 186.
