Wyrzysk () is a town in Poland with 5,263 (2004) inhabitants, situated in Piła County, Greater Poland Voivodeship. Geographic location Wyrzysk is located in the ethnocultural region of Krajna in northern Greater Poland, administratively it is part of the Greater Poland Voivodeship. History The Wyrzysk area was established first by East Germanic settlement at the beginning of the first millennium A.D. In the Middle Ages the Noteć became a natural border between the regions of Greater Poland and Pomerania, and the area became part of the emerging Polish state in the 10th century under the Piast dynasty. Later on, it long resisted the expansion of the German margraves, and since the 13th century also the Teutonic Knights. With time, local people adopted the Polish name Krajna for the area to the north of the Noteć. Eventually Polish ruler Bolesław III Wrymouth (1106–1138) conquered the castles on the Noteć and incorporated Krajna into the Kingdom of Poland for the next 700 years. The first preserved mention of Wyrzysk dates back to 1326; the name of the place was then recorded in the so-called Greater Poland Codex. Wyrzysk was probably granted the royal charter before 1450; in 1565 it became a town under the so-called Magdeburg law. Administratively, it was located in the Kalisz Voivodeship in the Greater Poland Province of the Polish Crown. As a result of series of wars in the second half of 17th century and beginning of 18th Wyrzysk became in fact a village. Wyrzysk was annexed by Prussia in 1772 in the First Partition of Poland. The town rights were renewed in 1773 by the Prussian King Frederick the Great who made the town a centre administering the construction of the Bydgoszcz Canal and the regulation of the Noteć. From 1807 to 1815 the town was a part of the Polish Duchy of Warsaw, established by Napoleon, and subsequently it was given back to Prussia as a result of Congress of Vienna. It remained Prussian until the end of First World War. The Prussian monarch and his successors aimed at Germanisation of the annexed lands. The methods included the ban on Polish language, introduction of Prussian administration and German language and education, encouraging and supporting Prussian settlement while discouraging any further Polish settlement in the area, as well as purchasing estates from the Polish gentry. Wyrzysk and some surrounding areas was sold by Karol Rydzyński, Roch Sypniewski
