Over the past few decades, a growing number of studies have highlighted the importance of the ‘School of Salamanca’ for the emergence of colonial normative regimes and the formation of a language of normativity on a global scale. According to this influential account, American and Asian actors usually appear as passive recipients of normative knowledge produced in Europe. This book proposes a different perspective and shows, through a knowledge historical approach and several case studies, that the School of Salamanca has to be considered both an epistemic community and a community of practice that cannot be fixed to any individual place. Instead, the School of Salamanca encompassed a variety of different sites and actors throughout the world and thus represents a case of global knowledge production.
