For decades, little research on Danish Cold War history was conducted either inside or outside Denmark. The relevant archives were closed, and generations of Danish contemporary historians were primarily interested in what happened during World War II. This is no longer the situation. Over the past 35 years, especially since the end of the Cold War, researchers have scrutinized Danish Cold War history in great depth. By now, scholarly research in Denmark on the Cold War, especially in the area of Danish national security affairs and foreign policy, has reached a level that merits international attention, and this survey article provides an overview. The article encourages Danish Cold War scholars to promote comparative research that incorporates Danish Cold War history into the wider international Cold War scholarship, to the benefit of both Danish and international research.
