Exile has characterised the history of Italian anti-fascism. Many antifascists, already from the early years of the regime, moved to the United States and Latin America, but especially to France, the UK and Switzerland, as far as the European continent was concerned. In this scenario, the role of the anti-fascist network in Switzerland, given its geographical location and its status as a neutral country, was decisive, especially during the early years of the Second World War. The key year is 1943 and, in particular, what happened after 8 September.
