Ignorance, amnesia, and selective remembrance have been recurring terms in discussions on Denmark’s (and Denmark-Norway’s) colonial history and active involvement in the transatlantic enslavement trade. The 2017 Centennial of Denmark’s sale in 1917 of the Caribbean islands of St. Thomas, St. John and St. Croix to the USA brought a new and unprecedented attention to this chapter of Danish history. The Centennial was marked in Denmark by a wide range of publications, exhibitions, debates and public events. Yet, attention does not automatically mean shifts in frameworks of national narratives of history and memory. With a starting point in the history of Danish colonial aesthetic – and contemporary artistic responses to these visualities – this lecture seek to discuss different strands of colonial memory cultures in Denmark today on a spectrum from persistent “un-visibility” to what I suggest to call “colonial sublime”.
