About the book: 2019 / What is the role of the common man in history? We know the names of monarchs, generals, revolutionaries, ideological leaders. But we will never know about those who walked in the countless crowd, led by the ideas of the great. Or is it still possible to look at the events of the past through the prism of the perception of a simple layman? Let's imagine a situation: a suitcase stuffed with papers, notes, newspaper clippings, and drawings is found in a landfill. Among this chaos, a diary of someone who lived in Petrograd at the very beginning of the 20th century is discovered. Troubled, rebellious times! One severe shock gives way to another. The First World War, popular unrest, strikes, collapse of the usual foundations. It was then that Evsei Kozlov lived, an ordinary city dweller who one day decided to start keeping a diary, which the modern reader now holds in his hands. Mr. Kozlov could hardly imagine what kind of people he would encounter, what events he would take part in, willy-nilly, or what interesting legacy he would leave for posterity..
