The oppressed classes make history in the factories, in the barracks, in the villages, on the streets of the cities. Moreover, they are least of all accustomed to write things down. Periods of high tension in social passions leave little room for contemplation and reflection. All the muses – even the plebeian muse of journalism, in spite of her sturdy hips – have hard sledding in times of revolution. Still the historian’s situation is by no means hopeless. The records are incomplete, scattered, accidental. But in the light of the events themselves these fragments often permit a guess as to the direction and rhythm of the hidden process. For better or worse, a revolutionary party bases its tactics upon a calculation of the changes of mass consciousness. The historic course of Bolshevism demonstrates that such a calculation, at least in its rough features, can be made. If it can be made by a revolutionary leader in the whirlpool of the struggle, why not by the historian afterwards?

However, the processes taking place in the consciousness of the masses are not unrelated and independent. No matter how the idealists and the eclectics rage, consciousness is nevertheless determined by conditions. In the historic conditions which formed Russia, her economy, her classes, her State, in the action upon her of other states, we ought to be able to find the premises both of the February revolution and of the October revolution which replaced it. Since the greatest enigma is the fact that a backward country was the first to place the proletariat in power, it behoves us to seek the solution of that enigma in the peculiarities of that backward country – that is, in its differences from other countries.

The historic peculiarities of Russia and their relative weight will be characterised by us in the early chapters of this book which give a short outline of the development of Russian society and its inner forces. We venture to hope that the inevitable schematism of these chapters will not repel the reader. In the further development of the book he will meet these same forces in living action.

This work will not rely in any degree upon personal recollections. The circumstance that the author was a participant in the events does not free him from the obligation to base his exposition upon historically verified documents. The author speaks of himself, in so far as that is demanded by the course of events, in the third person. And that is not a mere literary form: the subjective tone, inevitable in autobiographies or memoirs, is not permissible in a work of history.

However, the fact that the author did participate in the struggle naturally makes easier his understanding, not only of the psychology of the forces in action, both individual and collective, but also of the inner connection of events. This advantage will give positive results only if one condition is observed: that he does not rely upon the testimony of his own memory either in trivial details or in important matters, either in questions of fact or questions of motive and mood. The author believes that in so far as in him lies he has fulfilled this condition.

There remains the question of the political position of the author, who stands as a historian upon the same viewpoint upon which he stood as a participant in the events. The reader, of course, is not obliged to share the political views of the author, which the latter on his side has no reason to conceal. But the reader does have the right to demand that a historical work should not be the defence of a political position, but an internally well-founded portrayal of the actual process of the revolution. A historical work only then completely fulfills the mission when events unfold upon its pages in their full natural necessity.

For this, is it necessary to have the so-called historian’s “impartiality”? Nobody has yet clearly explained what this impartiality consists of. The often quoted words of Clemenceau that it is necessary to take a revolution “en bloc,” as a whole – are at the best a clever evasion. How can you take as a whole a thing whose essence consists in a split? Clemenceau’s aphorism was dictated partly by shame for his too resolute ancestors, partly by embarrassment before their shades.

One of the reactionary and therefore fashionable historians in contemporary France, L. Madelin, slandering in his drawing-room fashion the great revolution – that is, the birth of his own nation – asserts that “the historian ought to stand upon the wall of a threatened city, and behold at the same time the besiegers and the besieged”: only in this way, it seems, can he achieve a “conciliatory justice.” However, the words of Madelin himself testify that if he climbs out on the wall dividing the two camps, it is only in the character of a reconnoiterer for the reaction. It is well that he is concerned only with war camps of the past: in a time of revolution standing on the wall involves great danger. Moreover, in times of alarm the priests of “conciliatory justice” are usually found sitting on the inside of four walls waiting to see which side will win.

The serious and critical reader will not want a treacherous impartiality, which offers him a cup of conciliation with a well-settled poison of reactionary hate at the bottom, but a scientific conscientiousness, which for its sympathies and antipathies – open and undisguised – seeks support in an honest study of the facts, a determination of their real connections, an exposure of the causal laws of their movement. That is the only possible historic objectivism, and moreover it is amply sufficient, for it is verified and attested not by the good intentions of the historian, for which only he himself can vouch, but the natural laws revealed by him of the historic process itself.

The sources of this book are innumerable periodical publications, newspapers and journals, memoirs, reports, and other material, partly in manuscript, but the greater part published by the Institute of the History of the Revolution in Moscow and Leningrad. We have considered its superfluous to make reference in the text to particular publications, since that would only bother the reader.
