The final volume of Robert Service’s major trilogy on Lenin’s political life takes the account from the Brest-Litovsk Treaty of 1918 to the Bolshevik leader’s death in 1924. Attention is paid to the military, political and economic conditions as they changed; to the internal pressures of the party’s politics; to ideological imperatives; and to one man’s reaction to events and situations he had only imperfectly anticipated. The volume incorporates not only the post-1985 documentary revelations but also the results of the author’s searches in the Moscow archives since 1991.
