On July 6, 1415, the Czech priest and church reformer Jan Hus ended his life in Constance on Lake Constance. During his public activity, which lasted less than fifteen years, he won the admiration and love of a significant part of the Czech population, including their highest echelons, raised a number of disciples and followers, and aroused the opposition and hatred of the representatives of the Czech and European churches, as well as many of his fellow priests who knew him personally or from reading his theological texts. Even the Council of Constance, convened at Lake Constance in 1414, had to pay attention to Hus' person and his theology in order to save and reform the church of that time.
