West–East entanglements during the Cold War: shortwave broadcasting and propaganda from and to Portugal

Portugal became the centre of an entangled airwaves ensemble during the Cold War. In order to demonstrate this, the article develops along two lines. First, it details how the Portuguese dictatorship, with ideological connections to fascism, allowed the construction in its territory of one of the most powerful retransmitters of Radio Free Europe (RFE), responsible for airing anti-communist propaganda to Eastern Europe. The collaboration between the Portuguese dictator and the National Committee for Free Europe, mediated by US diplomatic officials, played an important role in the development of the operations of RFE in the country. Second, the article demonstrates how Portugal became the target of shortwave broadcasts operated from abroad, aimed at spreading pro-communist and anti-fascist sentiments in Portuguese society. Some of these stations were established by the political opposition that used the airwaves to undermine the dictatorship.
