The Russian Revolution was the event with the most consequences in the 20th century: it was a source of inspiration for communist movements and revolutions worldwide; it triggered reactions in the form of fascism, and after 1945 it had a clear impact on most anti-imperialist movements and shaped the architecture of international relations during the Cold War. For the reader interested in delving into the subject, the book presents a detailed account of the main events and developments from 1917 to 1929. It follows the ambitions and ideals that inspired those who fought for power, the problems they faced, and the conflicts between them. However, it is not limited to politics in the narrow sense of the term: the October Revolution aimed to destroy an entire social system and replace it with a society superior to any that had existed in human history until then. The book explores the difficulties and obstacles that stood in the way of achieving this goal, and the results of the Revolution on society and the economy, power structures and institutions, the family, the legal order, education, and culture.
