Our aim in this series is an attempt to reconstruct this period using the testimonies and the stories of the protagonists themselves. We have devoted many pages to the revolutions in Russia and in Germany. Therefore, we are publishing this work on lesser-known experiences in various countries with the aim of giving a global perspective. Studying this period a little, one is astonished by the number of struggles that took place, by the magnitude of the echo from the revolution of 1917.”
