Acta Periodica Duellatorum (APD) is an independent, international, and peer-reviewed journal dedicated to Historical European Martial Arts studies. This emerging field of research has strong interdisciplinary dimensions with notably History, Anthropology, Historical sciences, Art History, History of Science and Technology, Archaeology, Sport Sciences, etc. APD was founded in 2013 and publishes two issues per year from 2016 on. The Scholarly volume offers an academic level platform for fundamental research, position papers and methodological papers, with a double blind peer review process. The Hands On volume offers a platform for pragmatic research, intended for the communities of practitioners, bridging the gap between experienced martial artists, independent researchers and scholars. APD is a non for profit association, based in Switzerland. It is supported by institutional grants, donators/partners and by its readers. The journal is published electronically (open-access) and printed for subscribed readers and institutions.
