This article examines the ways in which British Second World War conscientious objectors (COs) have been commemorated, memorialized, and represented since 1945. Despite comprising nearly 60 000 men, the CO is strikingly absent in both the popular narrative of the Second World War and official, institutional commemorations of the conflict. This is not true of their First World War counterpart. This is unsurprising: the Second World War CO is largely at odds with popular British conceptions of the war as a ‘just’ conflict. Nevertheless, a broad and diverse set of initiatives have been established to commemorate the CO. The CO also features in numerous forms of post-war popular culture, including fiction, films, television programmes, and plays. It is these disparate remembrance practices and representations that this article brings together to help us explore both the memory of wartime conscientious objection and the broader cultural legacies of the Second World War.
