Mrągowo

Mrągowo mroN'gowo (until 1947 Ządźbork 'żońdźbork; ) is a resort town in the Warmian-Masurian Voivodeship of northeastern Poland, with 21,889 inhabitants (2019). It is the capital of Mrągowo County and the seat (though not part of) the Gmina Mrągowo. The town is located in the historical region of Masuria, within the Masurian Lake District, about east of Olsztyn. It is situated on the shores of lakes Czos, Sutapie Małe, Sołtysko, Czarne, Juno and Piecuch. About 1348 the Teutonic Knights constructed a wooden fortress near present-day Mrągowo named Sensburg, derived from Old Prussian senas meaning "old", therefore maybe at the site of a former Prussian castle. The settlement that began to develop nearby was first mentioned in a 1397 deed and probably had already received Kulm town rights between 1404 and 1407, although it is verified that Grand Master Konrad von Erlichshausen affirmed town rights in 1444. In 1454 it was incorporated to Poland by King Casimir IV Jagiellon upon the request of the anti-Teutonic Prussian Confederation, and after the subsequent Thirteen Years’ War (1454–1466) it was a part of Poland as a fief. To the town's Polish population it was known as Ządźbork. Ządźbork became part of the Duchy of Prussia, a vassal state of Poland, in 1525. In the 15th and 16th centuries, the town suffered through fires and plagues. Part of the Kingdom of Prussia since 1701, the town was incorporated into the Province of East Prussia after its creation in 1773. It was heavily devastated during the Napoleonic Wars. It remained mostly a small hamlet in the largely rural area around it. Agriculture, fishing and the richness of the surrounding forests provided the sources of income for the local population. Just like all of Masuria the district was inhabited mainly by Poles, and town itself had majority Polish population in 1816 however in the 19th century their percentage began to decrease due to Germanisation, removal of the Polish language from schools and the pressure of the local German administration (from 86% in 1825 to 59% in 1890).
