コンスタンツ公会議
When, on 11 October 1414, Hus left for the Council of Constance, Jerome assured him that if needed, he would come to his assistance, contrary to the wishes of Hus. Hus was tricked into attending the Council of Constance by means of a letter promising immunity, and upon his arrival in the city he was arrested and imprisoned. Jerome kept his promise, even though Hus and other friends of Jerome warned him not to come. On 4 April 1415, he arrived at Constance. Predictably, he created a stir in the town.
