拉瓦省
The oldest known mention of Skierniewice comes from 1359, although it existed earlier. A palace of the archbishops of Gniezno already existed in the village at that time. Skierniewice gained municipal rights in 1457 and was vested with various privileges in 1456–1458. Administratively it was part of the Rawa Voivodeship of the Greater Poland Province of the Polish Crown until the Partitions of Poland. Skierniewice was located on a trade route connecting major Polish cities Toruń and Lwów. Local merchants also participated in trade with Gdańsk, Lesser Poland and Podolia, as well as German states. One yearly fair took place since 1457, in 1527 King Sigismund I the Old established a second fair, and in 1641 the Sejm established two more fairs. The town suffered in the 18th-century as a result of the Swedish invasion of Poland and epidemics, and in 1793 it was annexed by Prussia in the Second Partition of Poland.
