Slavic Lechitic settlements were established in present-day districts of Ciechocino and Pieleszewo in the Early Middle Ages. The territory of Gdańsk Pomerania formed part of Poland since the establishment of the state in the 10th century. A wooden church existed at the site since the 12th century. In 1309 the area was annexed by the State of the Teutonic Order. It was first mentioned in documents in 1357. The area was re-incorporated to the Kingdom of Poland in 1454 by King Casimir IV Jagiellon, and after the subsequent Thirteen Years' War the Teutonic Knights renounced any claims in 1466. Reda and present-day districts Ciechocino and Pieleszewo were royal villages of the Polish Crown, administratively located in the Puck County in the Pomeranian Voivodeship in the province of Royal Prussia in the Greater Poland Province. In 1768 Ernest Konopacki obtained permission from the King of Poland Stanisław August Poniatowski to build a brass products factory.
