Has the internet changed the nature of conducting controversies? This question cannot be answered easily as different forms of human interaction in an online environment exist and controversies in an online environment have not been analyzed from a linguistic point of view so far. On the other hand, there are many linguistic analyses of controversies in the Early Modern Period. First, this volume describes the communicative background of two online discussion forums dedicated to the study of historical arms and armor. Then, the volume analyzes the similarities and differences between Early Modern controversies and controversies in online internet discussion forums.
