In this article, we analyze 28 YouTube video tributes to fallen Danish soldiers in Afghanistan and Iraq with two analytical goals. The goals are to first understand how the soldier as an object of communal grief is affectively and discursively established, discussed, and challenged in the videos and comments, and second to investigate what type of commemorative practices the specific media space of YouTube enables. Our first observation is that the videos’ attempts to construct the soldiers as national heroes and common objects of grief are repeatedly disputed and opposed by the people commenting on them. Our second point is that YouTube allows for a new type of commemorative practice, which, unlike the traditional war monuments of the nation-state, is marked by explicit differences of opinion concerning the status and legitimacy of the war. The analysis draws on theoretical insights from the fields of affect theory, participatory culture, DIY media, and memory studies.
