In the conclusion of her book Danmarks gamle Tropekolonier (Denmark's Old Tropical Colonies) from 1946, geographer, writer and traveler Sophie Petersen wrote that ved Siden af Sorgen over, at disse [de tidligere kolonier] ikke laenger er dansk Jord, [er der] ogsaa. .. Mulighed for Glaede over, at der er saa mange Minder tilbage derude om Danmark baade i Form af Bygningsvaerker og i Menneskers Minde. Derfor er det en stor Oplevelse for en Dansk at faerdes i vore gamle Tropekolonier, i Egne, hvor Slaegt efter Slaegt af Danske har virket, og hvor Dannebrog engang har vajet i mer end 200 Aar. (Petersen 1946, 407) (while there is regret that they [the former colonies] are no longer Danish soil, [there is also] an opportunity for joy, for there are so many memories about Denmark on the islands, both in the form of buildings and in the people's memory. It is therefore an incredible experience for a Dane to visit our old tropical colonies, where generations of Danes once worked, and where the "Dannebrog" flew for more than 200 years.) Petersen's Danmarks gamle Tropekolonier and the multivolume Vore gamle Tropekolonier (Brøndsted 1952-53 and 1966-68; Our Old Tropical Colonies) were for a long time among the most influential publications on Danish colonial history. Petersen's book is part historiography and part travelogue from her extensive travels, and the chapters are organized accordingly: they start with overviews of the history of the respective places, and end with sections about the situation at the time of the author's travels, for instance "A visit to present India." Petersen's travels to Danish former colonies are travels on a collective memory lane, and nostalgia is easy to discern. Commemoration and Tourism The memory of, and travel to, Danish ex-colonies is gaining new relevance in the context of the 2017 commemoration of the transfer of the former Danish West Indies, today's US Virgin Islands, to the United States in 1917. It seems that with the commemoration, a new phase is reached of Danish cultural remembrance of the circum-Atlantic colonial history and the triangular trade. There is a clearly recognizable new interest in the former Danish Caribbean islands: journalistic, artistic, political, and not least touristic. A large share of the material for this article on Danish tourism to former colonies is, indeed, advertisement for "jubilaeumsrejser," anniversary trips, to "Dansk Vestindien," the name still widely used in Denmark for the US Virgin Islands. Ian Gregory Strachan argues that "tourist advertising. .. maps and commodifies the region for the world consumer" (2002, 1). Tourism and tourism advertising can be seen as complicit with colonial and capitalist practices, and this complicity has specific implications in the case of tourism to former colonies. Another argument for the inclusion of tourism in studies of postcolonial relations is that scholars of tourism have found evidence for what they call "lingering effects of colonialism on tourist movements" (McKercher and L'Espoir Decosta 2007).
