This edition is the second book of essays on the history of the Russian Social Democratic movement, written by the Mensheviks, eyewitnesses of the events of those days - B. Nikolaevsky, S. Volin and G. Aronson. Not always objectively and critically written, these materials, however, are an indispensable source for all those who study the history of the Russian revolution, the era of the civil war and the revolutionary, primarily social democratic, movement in Russia.
