World War I has left deep marks in humanity's collective memory. Historians regard it as an event that shaped fundamentally the worlds we live in today. Major debates concerning the nature of war have been held over the past two decades and the frequency of commemorations should no longer surprise anyone. In continental Europe, the remembrance of the First World War caused in the last decade a veritable invasion of the past into the heart of the present. The main task of this volume remains to find out answers about Romanian belligerence. As you know, after 14/27 august 1916, The Kingdom of Romania faced this new challenge in the unpredictable course of the Great War. Naturally, the event had vivid echoes both at that remote time in the past, as well as during the course of the troubled century that separates us from the generation of the trenches. The blanket of reflection has descended over our minds, sometimes laden with bias and hatred, some other times filled with ideological expression serving one party ideology or another, but this elapsed period has mostly been useful, productive and necessary. So far the importance of the new Romanian front – was it marginal? was it crucial? – has not yet been established. Enough controversial issues are still being debated: the political commitments made before joining the war; the military training of the Romanian army; how the resources of the Romanian territory have been used; changes in battle tactics and strategic approaches etc.
