At the end of the 12th and in the 13th century, several foundations of monastic orders were established in Gdańsk Pomerania, endowed with relatively large land holdings. Among them were the Cistercian abbeys in Oliwa (founded around 1188) and Pogódki (established in 1258 and relocated to Pelplin in 1276), as well as the Cistercian nunnery in Żarnowiec, subordinated to the Oliwa monastery (founded before 1257). The Premonstratensian nuns in Żukowo (established in 1209) and the Knights Hospitaller (possessing lands around Lubiszewo, Skarszewy, and Starogard since 1198) also held rural estates in the region. Smaller estates belonged to the Benedictines (the priory in Święty Wojciech, founded at the turn of the 12th and 13th centuries and dependent on the Mogilno monastery) and the Augustinians in Swornegacie (established around 1255). From 1283, the Teutonic Order also established a presence in the area (Gniew lands). This presentation will outline the organization and functioning of the economy on the estates of these monastic orders, with particular attention to their relations with the authorities (local dukes or princes).
