This essay takes the novel The Museum of Unconditional Surrender by Dubravka Ugrešić as a starting point for a discussion of why the notion of a post-Yugoslav or post-communist cultural memory seems to be a contradiction in terms. The manifest impossibility of forming a collective post-Yugoslav memory provokes a reflection on how cultural and collective memory has been used in post-communist Eastern Europe to historify the communist past, which further has served the revival of a nationalist agenda. Ugrešić offers a counter memory, if we understand the term from Foucault as something that escapes the forming of identities. Finally, I suggest the notion of negative memory, as introduced by Reinhardt Koselleck, as a more apposite term for approaching memory in the post-communist sphere and in the unfolding catastrophes of the modern world.
