Deutschordensstaat
Kartuzy was established about 1380 as a monastery for Carthusian monks descending from Prague in the Kingdom of Bohemia, after whom it received its name. The charterhouse was vested with large estates by the State of the Teutonic Order. According to the Second Peace of Thorn the area passed to the Polish Crown in 1466, within which it was administratively part of the Pomeranian Voivodeship in the provinces of Royal Prussia and Greater Poland.
