Johan Huizinga and Henri Pirenne belong to the most prominent historians of the twentieth century. The fame of the former is most of all based on Herfsttij der Middeleeuwen (1919), a fascinating study of the Burgundian culture; the latter is widely considered as the innovator of the economic and urban history of the Middle Ages. But both historians were equally highly preoccupied by the question as to which position their countries - the Netherlands in the case of Huizinga, Belgium in the case of Pirenne - should take up in Europe and what were the responsibilities of these engagements in an international community. This preoccupation is the subject of this essay. It tells the story of diplomats from small countries, of disappointment through war and of national pride, a story also in which positions changed repeatedly.
