J. Smith 
The Bolsheviks and the National Question, 1917–23 [PDF ebook] 

In a timely re-examination of the origins of the system which fell apart so dramatically in 1991, this book deals with the policies of the Soviets towards the non-Russian nationalities of the former Russian Empire. Making extensive use of previously unavailable material from the Soviet archives, Jeremy Smith explores the attempts of the Bolsheviks to promote the development of minority nationalities in the Soviet context, through a combination of political, cultural and educational measures, and looks at the disputes surrounding the creation of the Soviet Union.
