Richard Pipes, The New York Review of Books:
"This is a very serious biography that... is likely to well stand the test of time."

The Wall Street Journal:
"Superb . . . Mr. Kotkin's volume joins an impressive shelf of books on Stalin. Only Mr. Kotkin's book approaches the highest standard of scholarly rigor and general-interest readability."

New Statesman (UK)
"[Kotkin's] viewpoint is godlike: all the world falls within his purview. He makes comparisons across decades and continents.... An exhilarating ride."

Anne Applebaum, The Atlantic

"An exceptionally ambitious biography... Kotkin builds the case for quite a different interpretation of Stalin--and for quite a few other things, too. The book's signature achievement... is its vast scope: Kotkin has set out to write not only the definitive life of Stalin but also the definitive history of the collapse of the Russian empire and the creation of the new Soviet empire in its place."

Robert Gellately, Times Higher Education (London)
"A brilliant portrait of a man of contradictions... In the vast literature on the Soviet Union, there is no study to rival Stephen Kotkin's massive first instalment of a planned three-volume biography of Joseph Stalin. When it is complete, it will surely become the standard work, and I heartily recommend it."

John Thornhill, Financial Times:
"It is a measure of Kotkin's powers of research and explanation that Stalin's decisions can almost always be understood within the framework of his ideology and the context of his times.... With a ferocious determination worthy of his subject, the author debunks many of the myths to have encrusted themselves around Stalin.... [A] magnificent biography. This reviewer, at least, is already impatient to read the next two volumes for their author's mastery of detail and the swagger of his judgments."

David Johnson, Johnson's Russia List
"Required reading for serious Russia-watchers... As the product of years of work and careful thought, it is for me a reminder of what it takes to get close to the truth about important and controversial subjects. And the distance and time required to do so."

Geoffrey Roberts, Irish Examiner
"Monumental... For Kotkin it was not Stalin's personality that drove his politics but his politics that shaped his personality. His research, narrative and arguments are as convincing as they are exhaustive. The book is long but very readable and highly accessible to the general reader.... Magisterial."

Donald Rayfield, Literary Review:
"Masterful... No other work on Stalin incorporates so well the preliminary information needed by the general reader, yet challenges so thoroughly the specialist's preconceptions. Kotkin has chosen illustrations, many of them little known, which reveal the crippled psyches of his dramatis personae."

Booklist (starred):
"An ambitious, massive, highly detailed work that offers fresh perspectives on the collapse of the czarist regime, the rise of the Bolsheviks, and the seemingly unlikely rise of Stalin to total power over much of the Eurasian land mass....This is an outstanding beginning to what promises to be a definitive work on the Stalin era."

Kirkus Reviews (starred):
"Authoritative and rigorous.... Staggeringly wide in scope, this work meticulously examines the structural forces that brought down one autocratic regime and put in place another."

Publishers Weekly
"This is an epic, thoroughly researched account that presents a broad vision of Stalin, from his birth to his rise to absolute power."

Library Journal
"Kotkin has been researching his magisterial biography of Stalin for a decade. Inescapably important reading."

John Lewis Gaddis, Yale University; author of George F. Kennan: A Life, winner of the 2012 Pulitzer Prize for Biography:
"In its size, sweep, sensitivity, and surprises, Stephen Kotkin's first volume on Stalin is a monumental achievement: the early life of a man we thought we knew, set against the world--no less--that he inhabited. It's biography on an epic scale. Only Tolstoy might have matched it."

William Taubman, Professor of Political Science Emeritus, Amherst College; author of Khrushchev: The Man and his Era, winner of the 2004 Pulitzer Prize for Biography
"Stalin has had more than his fair share of biographies. But Stephen Kotkin's wonderfully broad-gauged work surpasses them all in both breadth and depth, showing brilliantly how the man, the time, the place, its history, and especially Russian/Soviet political culture, combined to produce one of history's greatest evil geniuses."

David Halloway, Raymond A. Spruance Professor of International History, Stanford University; author of Stalin and the Bomb
"Stephen Kotkin's first volume on Stalin is ambitious in conception and masterly in execution. It provides a brilliant account of Stalin's formation as a political actor up to his fateful decision to collectivize agriculture by force. Kotkin combines biography with historical analysis in a way that brings out clearly Stalin's great political talents as well as the ruthlessness with which he applied them and the impact his policies had on Russia and the world. This is a magisterial work on the grandest scale."

Strobe Talbott, president of the Brookings Institution:
"More than any of Stalin's previous biographers, Stephen Kotkin humanizes one of the great monsters of history, thereby making the monstrosity more comprehensible than it has been before. He does so by sticking to the facts--many of them fresh, all of them marshalled into a gripping, fine-grained story."

The Sunday Times (London)
"Staggeringly researched, exhaustively thorough... Kotkin has no patience for the idea that Stalin... was a madman or a monster. His personality and crimes, Kotkin thinks, are only explicable in the wider contexts of Russian imperial history and Marxist theory. So this is less a conventional biography than a colossal life and times.... Hugely impressive."

Sheila Fitzpatrick, The Guardian:
"Unlike a number of Stalin studies, this is not an etiology of evil. The author does not appear to be watching his subject narrowly for early signs of the monstrous deformations that will later emerge. He tries to look at him at various stages of his career without the benefit of too much hindsight.... [Kotkin] is an engaging interlocutor with a sharp, irreverent wit... making the book a good read as well as an original and largely convincing interpretation of Stalin that should provoke lively arguments in the field."
