🇵🇱 Wyszków is a town in eastern Poland. It is the capital of Wyszków County in Masovian Voivodeship.
History The village of Wyszków was first documented in 1203. It was granted town rights in 1502. It was administratively located in the Kamieniec County in the Masovian Voivodeship in the Greater Poland Province of the Kingdom of Poland. It was destroyed during the Swedish invasion of Poland (Second Northern War) in 1655–1660, and it lost its significance in the region.
It was annexed by Prussia in the Third Partition of Poland in 1795. In 1807 it was regained by Poles and included within the short-lived Polish Duchy of Warsaw, and in 1815 it passed to Russian-controlled Congress Poland. In 1870 it was deprived of its town rights, as one of many Polish town punished by the Russians for the unsuccessful Polish January Uprising. Industry developed after 1897, when the Pilawa-Tłuszcz-Ostrołęka railway was built. In 1918 Poland regained independence and control of Wyszków, and in 1919 town rights were restored.
