This Introduction sets out the intentions of this book: to use the rich witch-trial records from the early modern duchy of Württemberg in south-western Germany to explore the central themes of emotions, gender, and selfhood. It provides an overview of the key historiographical debates on witchcraft persecutions in the early modern period, and suggests new questions that need to be asked. It also provides a methodological and theoretical framework in which to address these questions, and provides an overview of the current state of the field of the history of emotions, and, by drawing on psychological approaches to listening to self-narratives, it suggests ways in which historical studies of emotions can be pushed further by incorporating the body and subjective states. It also sets out the legal, political, and religious framework of the Lutheran duchy of Württemberg, in order to put the witch-hunts in this region into context.
