Nisko [ˈɲiskɔ] is a town in Nisko County, Subcarpathian Voivodeship, Poland on the San River, with a population of 15,534 inhabitants as of 2 June 2009. Together with neighbouring city of Stalowa Wola, Nisko creates a small agglomeration.
Nisko was first mentioned in a document dated 15 April 1439, in which King Władysław III of Varna handed the villages of Nysky, Zaoszicze and Pyelaskowicze to a local nobleman. Furthermore, Nisko was also mentioned by Jan Dlugosz, in his work Liber beneficiorum dioecesis Cracoviensis. The establishment of the village was probably the result of catastrophic Mongol Invasion of Poland, which decimated the population of Lesser Poland. Residents of burned villages and towns resettled in the areas north of the enormous Sandomierz Wilderness. Probably in the second half of the 13th century, a village was established on a hill near the San river.
Due to the location on the outskirts of the wilderness, local residents supported themselves by hunting and trade of timber, which was transported to other centers along the San and the Vistula waterways. In the 1570s, peasants from Nisko and other locations rebelled against the Starosta of Sandomierz, Andrzej Firlej. In 1578, they met with King Stefan Batory, who stayed in Tarnogrod, asking him for justice. The king supported the peasants, urging Firlej to come to Warsaw. On 10 November 1583, Batory issued a bill, in which he backed demands of the peasants.
