Our artwork of the month – the first instalment in this new series – is not from the interwar period: it was created in 2008-2009. It has been chosen as an introductory piece because it represents an important aspect of our research in a thought-provoking way. Our project considers Central Europe after 1918 as a shared cultural space, but in doing so it has to deal with the political reality: the newly minted nation states of the region and the new borders drawn between them. These borders – either their enforcement, or, as in the case of Hungary, their fervent contestation – were central to political discourse in all of these countries. The concept of the nation state relies on the idea that the ethnic, cultural and administrative borders of a nation should correspond with each other; this is, however, rarely the case in reality. The new states of Central Europe were not homogeneous either ethnically or culturally. In the Austro-Hungarian Monarchy, different ethnic groups had not only lived side by side, but also intermingled. After 1918 the population of the region underwent a radical mental shift from imperial multi-nationalism towards ethnic nationalism. Yet, multi-ethnicity was still present, and cultural transfer happened between ethnicities and across borders. What does this curious map tell us about all this? Let’s take a look.
