In this volume, Jan-Andrea Bernhard explores the history of relations between Switzerland and Hungary in the 16th and 17th centuries.The starting point of this study is the question of why the majority Hungarians who embraced the Reformation subscribed to the Helvetic Confession in spite of the fact that contact with Germany had been more intense. The author investigates the source material and the relevant research literature and then, making use of those source materials the author investigates how the interchange of knowledge between Switzerland and Hungary took place during the early modern period.Due to its comprehensive source evaluation, the investigation de-mythologises the Hungarian (Church’s) History in several areas, and in this regard is a milestone in the literature on the history of relations between Hungary and Switzerland.
