This chapter analyses the sources of international law in the nineteenth-century European tradition. It includes scholars and theorists from a range of nationalities, different professions and perspectives, focusing on selected authors from various European and American countries and regions between 1815 and 1914. These jurists, philosophers, political writers, and theologians discussed the notion of ‘source’ and elaborated extensively on a theory of sources. Within this canon of sources, no clear hierarchy existed, and no rules for the collision of different kind of sources were posited. The field thus remained very flexible for attaining any results when debating regulatory matters, although the authors claimed to be non-political.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
