As nationalist and populist rhetorics have gained momentum in Central and Southeastern Europe, there is an urgency to disentangle the historical narratives and political agendas displayed by national museum paradigms. And yet, equally significant is the urgency to illuminate the strategies and mnemonic devices through which the past is rendered worthy of commemoration, both in those memory cultures that come to life in opposition, or those which are complementary to the national museum’s paradigms. In line with these considerations, this special issue addresses the vernacular dimension of public memory, with a special focus on those memory cultures instantiated by mnemonic actors who do not necessarily possess the public epistemic authority to materialize their narratives about violent pasts as official memories.
