This study is devoted to the examination of the image of Rudolph IV of Austria in the historical writings of Henry Truchsas of Diessehofen. His chronicle, which maps the years 1316-1361, deals primarily with the history of the Empire; however, the attention of the author of this article is continuously drawn to the history of the Dukes of Austria, which is closely related to this area. The author try to explain the silence of the chronicler on the Rudolph’s participation in the allegiance formed by the Dukes of Württemberg in 1359, which was potentially aimed against Emperor and Rudolph’s father-in-law Charles IV. and Georg Modestin.
