This article examines a case study of international Communist propaganda during the Cold War. The Institute of Historical and Socio-Political Research (ISISP), a historical propaganda organization affiliated to the Romanian Communist Party (RCP), succeeded in penetrating the Iron Curtain by distributing its works through a social network provided by the Italian Liberation Movement Institute, and in publishing its works in Italy, with the help of the Gramsci Institute, as well as publishers like Editori Riuniti and Nicola Teti. The ISISP established a mutually beneficial partnership with various Italian actors: ISISP and the regime succeeded in publishing international propaganda; the Italian publishing houses were paid by ISISP to print and distribute their edited volumes, with the double advantage of keeping political ties with the RCP while also protecting their own limited finances.
