Sciences and technology in the beginning of XX century were developing at a fast pace: radio, electricity, cinematograph, automobiles… Millions of Europeans could hardly catch up with the swift scientific and technological advance and they were unable to surmise that something threatens their lives. But in 1914 a war emerged that humanity had never seen before. The first war of armored machines and airplanes, machineguns and poison gases. The war that began with the murder of two people and ended with over 10 million deaths and the ruining of four empires. World War I that changed the face of Europe and the whole world for ever.
