The exodus provoked by the Civil War (1936–1939) is, due to its magnitude, the principal field of study on Spanish exile. Nevertheless, during the Spanish Republic in peacetime (1931–1936), different exiles took place which have not raised as much interest within the historiography. This is the case of those that had to flee Spain after being involved in the October Revolution of 1934. They were anonymous activists, the middle ranks, and also well-known leaders of the working-class movement, many of whom would play an important role during the time of the Popular Front, the Civil War and exile. In order to carry out this study, the archives of the five French départements bordering Spain, the Archives Nationales and the Archives de la Préfecture de Police in Paris were consulted. That facilitated identifying two hundred and seventy-five refugees, as well as understanding important aspects of their route towards exile, how they crossed the border, what their the journey was and the vicissitudes they experienced in French territory and what the conduct of the French authorities was.
