Recently, efforts have been made to integrate each of the cases in a post-imperial paradigm, identifying the complex interactions between their socio-political modernisation and historical memory. This book continues this trend by investigating for the first time the two cases together, as parts of a space of alterity, as labs of shifting ideologies and labels. The public figures and the institutions depicted in the book are physically located in Central and in Eastern Europe, but by sometimes competing experiences they are illustrative for several identities and historical realms, local, regional, and continental. Secondly, the current work addresses dilemmas related to Nationalism and nation building, for the sake of separating those discourses which reflected on civic nationalism from those which directed the public mind to the values of ethnic nationalism.
