This book is among the rare contributions to the 150th anniversary of 1848 which takes a completely new, theoretically informed approach. Instead of a traditional social or political history, the authors analyse the dichotomy between the international dimension in the ideas of the revolution and the nationalisation of memories in its commemorations over the past 150 years. The book offers original research on the history of European ideas and takes part in the current debate about the relationship between history and memory.
