This paper examines how, in politically polarized contexts, people reconstruct the biographies of contested memorialized figures to challenge or reproduce dualistic metanarratives of national history. We analyze two sites of recent controversy in Scotland and Lithuania which have been engaged in struggles over how to memorialize individuals who, at various points in their lives, engaged in acts of both anti-imperial resistance and collaboration in those same empires’ systems of oppression. Their moral liminality—a term we employ to refer to the transgression of moral categories—blurs the boundaries between perpetrators and victims of imperial violence, calling into question binary frameworks underpinning broader national narratives. Based on a comparative media analysis of debates over the legacies of David Livingstone and Jonas Noreika, we find that though some people in both Scotland and Lithuania have embraced these figures’ moral liminality, others have, instead, suppressed aspects of their biographies to uphold traditional distinctions between national “heroes” and foreign “villains.” We argue that such moral binaries are either blurred or reproduced through the manipulation of three aspects of liminal figures’ biographical records: their agency, motives, and social impact.
