The contributors to the present volume approach World War I and World War II as complex and intertwined crossroads leading to the definition of the new European (and world) reality, and deeply pervading the making of the twentieth century. These scholars belong to different yet complementary areas of research – history, literature, cinema, art history; they come from various national realities and discuss questions related to Italy, Britain, Germany, Poland, Spain, at times introducing a comparison between European and North American memories of the two World War experiences. These scholars are all guided by the same principle: to encourage the establishment of an interdisciplinary and trans-national dialogue in order to work out new approaches capable of integrating and acknowledging different or even opposing ways to perceive and interpret the same historical phenomenon. While assessing the way the memories of the two World Wars have been readjusted each time in relation to the evolving international historical setting and through various mediators of memory (cinema, literature, art and monuments), the various essays contribute to unveil a cultural panorama inhabited by contrasting memories and by divided memories not to emphasise divisions, but to acknowledge the ethical need for a truly shared act of reconciliation.
