When Flanders and Holland became part of the Duchy of Burgundy, Burgund Dutch and Prussian cities increasingly excluded Lübeck from their grain trade in the 15th and 16th century. Burgund Dutch demand for Prussian and Livonian grain grew in the late 15th century. These trade interests differed from Wendish interests, threatening political unity, but also showed a trade where the Hanseatic system was impractical.[12]: 198, 215–216  Hollandish freight costs were much lower than the Hansa's, and the Hansa were excluded as middlemen.[citation needed] After naval wars between Burgundy and the Hanseatic fleets, Amsterdam gained the position of leading port for Polish and Baltic grain from the late 15th century onwards.[citation needed]
