This article aims to demonstrate and investigate how natural law and law of nations theories were used and adapted within the context of the Italian peninsula of the late eighteenth century. It proposes to retrace the ways in which the texts of the so called Ecole romande du droit naturel and particularly the Droit des gens ou principes de la loi naturelle, appliqués à la conduite et aux affaires des Nations et des Souverains by Emer de Vattel (1758) were used in and adapted to the Italian environment, which was extremely different from the one in which these texts were written and published, in order to contribute to the legal transformation process of the Italian states during the eighteenth century.

本文旨在展示和研究在十八世纪末的意大利半岛背景下如何使用和修改自然法和国家理论。它建议追溯所谓自然法典的文本，特别是《自然与民族的印记》，《 Emer de Vattel》（1758年） ）用于并适应于意大利的环境，这与撰写和出版这些文本的环境截然不同，以促进18世纪意大利各州的法律转型。
