Issue 1(10) includes the proceedings of the conference “A Day in the Calendar: Holidays and Commemorations as an instrument of national consolidation in Central, Eastern and South-Eastern Europe from the nineteenth to the twenty-first centuries”. The authors focus on the “invention of tradition”, the production, dissemination, and borrowing of practices of commemoration developed around major historical events, such as wars and revolutions, or holidays from the folk or church calendar; old and new holidays in the context of political change; and finally, holidays as markers of identity for peoples who lived in foreign ethnic and foreign language environments. The inclusion of articles on similar processes in neighbouring regions underlines the regularity and uniqueness of the historical development of Central Europe.
