When the political needs of governments, political parties, armed groups, etc., demand the making up of a past that justifies their specific present, their respective organs often seek to propagate a discourse that permeates the national social structure and allows the memory of the causes of past violence to be reinvented, through a strong perversion of history. In these situations, a trend known as historical presentism tends to emerge, i.e., the malformation of history and historical knowledge in the service of totalitarian projects, such as those of the Nazi and Soviet regimes in twentieth-century Europe, or identity-based nationalisms, sponsored by violent guerrillas, as in the case of the FARC-EP in Colombia. Two scenarios that exemplify singular manifestations of historical presentism in Europe and Latin America are given.
