Book excerpt: The events of 1989/90 in Europe demonstrated the renewed relevance of the mid-nineteenth century uprisings: both by showing, once again, how a revolutionary initiative could quickly spread through different European countries, but also by calling into question the nature of revolution and the criteria for a revolution's success and failure. To commemorate the 1848 revolution in a spirit of renewed critical inquiry, an international team of prominent historians have come together to produce what must be the most comprehensive work on this topic to date and to offer a synthesis that sums up the current state of scholarly research, emphasizing the many new interpretations that have developed over several decades.
