Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. I have tried in this book to elucidate, as far as was in my power, the development of the fundamental ideas of the Socialist parties in the Russian Revolution and their reflection in the life of the masses. A revolution is a very complex thing, especially in such an immense country as Russia, with its large and varied population, and it goes without saying that, far from claiming to have described it exhaustively, I realise only too clearly that there are numbers of questions on which I have barely touched.
