Long neglected, Gaetano Salvemini's years of exile (1925–1949) now constitute a crucial period for reconsidering his intellectual and political profile. This article intends first to propose an overall interpretation of Salvemini's exile that considers the years 1919 to 1925 as the culmination of a profound turning point in his life. The central part of the essay is devoted to reconstructing the genesis of Salvemini's relationship with the United States and dwells on the reflections written after his first trip overseas in 1927. In them it is possible to find a clear analysis of the impact of Fascist propaganda on American soil and a definition of the tasks that exiles were called upon to perform in their host countries. Building on these premises, the study rereads Salvemini's years of American exile by focusing on three aspects. Firstly, his great ability to adapt to the American academic world. Secondly, his commitment to the field of research, with works dedicated to the study of Fascism, some centred on a reinterpretation of the concept of democracy and others on the methodology of history. Thirdly, his prodigious activity carried out in the antifascist struggle.

加埃塔诺·萨尔维米尼长期被忽视的流亡岁月（1925-1949）现在构成了重新考虑他的知识和政治形象的关键时期。本文首先打算对萨尔维米尼的流亡生涯提出一个整体的解读，认为1919年至1925年是他人生中一个深刻转折点的顶峰。文章的中心部分致力于重建萨尔维米尼与美国关系的起源，并详细阐述了他 1927 年首次出国访问后所写的反思。在这些反思中，可以找到对法西斯宣传对美国的影响的清晰分析。美国的土壤和流亡者在东道国执行的任务的定义。在此前提下，本研究通过关注三个方面重新解读了萨尔维米尼的美国流亡岁月。首先，他具有很强的适应美国学术界的能力。其次，他致力于研究领域，其著作致力于法西斯主义研究，有些集中于对民主概念的重新解释，有些则集中于历史方法论。第三，他在反法西斯斗争中所进行的伟大活动。
