Compelle intrare : since the time of St Augustine, St Luke’s words in the parable of the Banquet have served as a justification for forced conversion to Christianity. Challenging this tradition, in 1686 Pierre Bayle denounced how a literal interpretation of the parable had led to a long line of crimes, and argued that nothing is more abominable than obtaining conversion by coercion . In recent decades, scholarly research on conversion in the Early Modern Age has increasingly focused on intriguing aspects such as the fluidity of converts’ identity and their crossing of borders - both geographical and confessional. This book takes a different perspective and brings the focus back to the dark side of conversion, to the varying degrees of violence that accompanied Catholic missionary activities in the non-European World in the 16th and 17th centuries. The essays collected here examine three areas where, sometimes visibly, sometimes much more subtly, the violent aspects of conversion took shape: doctrine, missionary practice, and the conversion narratives. Investigating the connection between violence and conversion is a way to reflect not only on the early modern world, but also on that of the present day, when conversion - including by coercion - has yet again become a significant issue.
