The causes of the war go back as far as the year 1371. The town had successfully held its ground against
Duke Magnus despite heavy losses. In all its debts amounted to 100,000 marks at the time, which the citizens did not want to discharge by themselves. The officiating
Wittenberg nobility decreed that, to reduce the debt, every resource available to the town (including the saltworks) had to be used. That affected the master salters (
Sülfmeister) who leased the
saltworks. They did not want to pay so much, however, and demanded as council members that the
prelates of the surrounding villages, who owned the business, should be more heavily taxed. The prelates refused to comply, arguing that the Lüneburg townsfolk were abusing their power and making excessive demands of the saltworks. The prelates succeeding in having the town
excommunicated; this was rescinded again in 1374. The prelates then agreed to increase their financial contribution on the condition that their property was protected. This concession was repeatedly confirmed (until the last occasion in 1388), because Lüneburg's debts continued to grow as a consequence of the
Lüneburg War of Succession. == Intensification of the conflict ==
