Collective, historical memory becomes increasingly important in public debates on cultural heritage across many countries. Their key elements are contested cultural objects – such as statues or memorials – which construct nations’ memory that governs societal processes such as decolonisation or de-Stalinization. This paper analyses arguments about five such objects in UK, US, South Africa, Poland and Spain in order to identify discursive strategies used to argue whether to remove or to keep them. Large-scale comparative discourse analysis reveals that the ethos of historical figures – such as the Confederates or Joseph Stalin – commemorated by these cultural objects plays an essential and primary role in these debates. We argue that values associated with the character of these figures determine the dynamics of discourse and its close analysis allows us to uncover what societies are struggling with when handling artefacts of the past in the present day.
