Bieńczyce, a village near Kraków, was a benefice of a parson of St Florian’s parish in Kleparz, providing his main source of income. In the 18th and 19th century the countryside witnessed a conflict between millers and peasants as well as a Rev. Antoni Krząnowski, and after his death Rev. Franciszek Kolendowicz. Three successive millers from the Upper Mill neglected their duties, which caused a gradual deterioration of the mill’s condition. The article focuses on the causes, course and results of conflicts over the mill in the years 1792–1838.
