Since the official history-writing is a defining aspect for the formation and consolidation of nation-states, it is crucial to explore the attempts to legitimize particular discourses regarding historical atrocities. The selective representations of the past, in this regard, contradict counter-memories and propagate hegemonic patterns of remembrance and/or forgetting of past crimes. This article accordingly addresses how the representations of counter-memories as threats to national security and the silencing of gender-specific experiences and remembrances by sanctioned historical narratives become manifest in the history-making of the Turkish nation-state. By focusing on the Holocaust and the Armenian Genocide as two cases of crimes against humanity, it is intended to discuss the shifting positions and roles that the Turkish state adopts in the remembering and forgetting of historical offences. The article argues that through prioritizing national security and national interests, the securitization of memory reconstructs collective traumas of distinct ethnic and religious groups on the basis of a nation-state’s perceived internal and external threats. It also claims that the competing voices of women and their distinct experiences and patterns of remembrance and forgetting past atrocities are suppressed for the sake of the preservation of national security. By incorporating the issue of gender into the debate on the securitization of memory, this article elucidates the mismatch between positions of femininity and masculinity within the official national historiography of the Turkish state.
