Abstract
In face of the growing systemic conflict between the West and China and the sudden escalation of tensions with Russia in the wake of the invasion of Ukraine, the concept of the Cold War reappears in recent years as a reference category. Terefore, the purpose of this article is to present an exhaustive and up-to-date review of the historiographical state of the art in relation to the concept, interpretations, physical and mental spaces and defining systemic structures of the world order between 1947 and 1991. Classic references are included, as well as the most recent, innovative and ground-breaking contributions to the historiography of the Cold War, which since 1991 has undergone a profound makeover, due to the broadening of interpretative categories and the multiplication of historiographical sources. Only by identifying what the Cold War really was will it be possible to construct valid comparative analyses, highlight lines of continuity, describe new variables and, ultimately, draw interpretative frameworks that allow us to understand a potential new cold war in light of the systemic confrontation during the second half of the twentieth century.
