September 1, 1939-September 2, 1945. World War II: six years and one day that marked humanity. Imagine Europe as a theatrical stage. On this huge stage, a performance of horror, hunger, deaths, displacements, anxiety, despair was given. Horror! However, the play was not imaginary. It was written by many authors, known and unknown, while the actors were also known and unknown. Year by year, the events will unfold on the pages of the book through the evidence, testimonies, and words of those who suffered the hardships of that war. We are lucky not to have lived it! But hundreds of millions of Europeans did, ordinary citizens, soldiers, resistance fighters, intellectuals, persecuted, politicians, children and adults, our own. The history of World War II was written in many languages!
