Issue 4(13) mainly includes articles examining Hungary as a factor in state, ethnic, and cultural interactions in Central Europe and neighbouring regions in modern and contemporary history. This millennium-old country, which over the centuries has changed the contours of its borders more than once, has played an important role both in dynastic alliances and international relations, and in the formation of national identity not only among the titular nation, but also among the non-Magyar peoples of the kingdom. The feeling of being a small nation in a linguistically-alien environment combined with the ideology of being the bearer of political culture found expression in social structure, culture, mentality, and traditions, which retained their strength and appeal regardless of changes in the political system, of which the twentieth century had many. The Hungarian theme emerges in the context of symbolic communication between Hungarian kings and their estates in the eighteenth century, the ecclesiastical and civil self-organization of the Serbs of the Kingdom of Hungary, reactions to the Compromise of 1867 on the rearrangement of the Austrian Empire, the historiography of the Romantic era and academic interactions in the twentieth century, and finally the sociocultural function of such a Hungary-associated genre as operetta.
