An important question underlines the following pages, why a cover of silence covered the experience of progressive and communist Jews in Chile? This article follows two Jewish progressive institutions from Chile: Sociedad Progresista Israelita (1938-1951) and Centro Cultural Scholem Aleichem (19511964). These two institutions gathered the main questions of Jews in the country: how to face the crucial events of international and national politics, during the Second World War and the Cold War. By revealing how the institutions worked and the type of activities in which they expressed their ideology, we can start to find the answer to why, in the Jewish Chilean context, their progressive voice was silenced.
