This volume concludes the history of Bari. In the latter part of the 19th century Bari underwent extraordinary development. The building of the Petruzzelli theatre in 1903 was the symbol of a rich and articulated process. At the end of the 20th century the fire that burnt down the same theatre marked the crisis of an entire ruling class. Does the history of Bari end like this? Evidently not because Bari has built much in this century and grown and the best of its past has strong roots. We must rediscover and pinpoint them in the culture and mentality of the people of Bari. This, in fact, is the main aim of this volume and moreover of the whole Storia di Bari: to know what is behind us and use it as a guide and solid resource for the future.
