Harbouring ambitions: The free port of Copenhagen, imagined futures, and the making of maritime nationhood

Large-scale transport infrastructures such as ports, railways, airports, and bridges are more than infrastructures of trade: they are arenas where national identity, state authority, and global commerce intersect. The Copenhagen Free Port, inaugurated in 1894, emerged amid intensifying Northern European competition, as Hamburg's Freihafen, the Kiel Canal, and steamship expansion pressured Denmark to modernise its port infrastructure. This article reconstructs the debates and compromises among state officials, financiers, merchants, and international actors that produced the free port. Moving between microhistory and broader historical contexts, it shows that the free port was not only a response to immediate pressures but also a projection of imagined futures in which Denmark could reassert maritime nationhood. The article argues that harbour transformations were not merely technical responses to global trade, but expressions of competing visions of national development, making ports crucial arenas where national authority and international openness were negotiated.
