Both Byszewo and Koronowo, the old and the new site of that Cistercian convent, were situated in the Diocese of Włocławek. Consequently, the convent’s fortunes were to a large extent dependent on the relations between its abbot and the local bishop. Bishop Michał (1222-1252) not only gave his consent to the founding of the convent but also provided much needed material support. His successors, however, preferred to cold-shoulder the Abbey.This attitude may have been the consequence of a new set of priorities, formulated by Michal’s successor Wolimir, which committed the bishops to the improvement of the economic basis of the Włocławek Bishopric. The lack of more intensive contacts or cooperation between Włocławek and Byszewo may have also been caused by the weakness of the Cistercian foundation in the early stage of its history. In addition, the relations were sullied by a dispute over the legal title to the Szpetal estate. Byszewo became party to that dispute after succeeding to the legacy of the liquidated convent at Sulejów.A turning point in the relations between the Abbey and the Bishopric came eventually in April 1288, when the convent of Byszewo obtained the permission to move to another place — later called Koronowo — in return for dropping all its claims to the Szpetal estate, which had come into the possession of the Bishop of Włocławek. Later Bishop Gerward was credited with the title of the benefactor of the monks; the custom to include the name of the local bishop in the monks’ daily prayers dates back to they ear time his successor took office (1362). Now the Cistercians of Byszewo could be seen taking part in the annual celebrations to mark the consecration of the Włocławek Cathedral, while the bishops acted as intermediaries and assisted the Byszewo monks in transactions involving the purchase of land. Although the relations improved, not everything could be taken for granted. So contacts remained somewhat irregular and the Włocławek bishops most probably did not stay at the convent while making pastoral visit in the vicinity.
