This article introduces the concept of ius gentium as it was conceived by Francisco Suárez in De Legibus. Throughout this work, Suárez analyzes and criticizes previous ideas on the ius gentium reaching a more complete examination of the concept. Thus, Suárez concludes with a new conception of the ius gentium that is compatible with the modern conception of international law and is not deducible from natural law alone.
