The Devils' Alliance: Hitler's Pact with Stalin, 1939-1941 - Hardcover

"The Devils' Alliance is a marvellous achievement. No event was more crucial to the outbreak of the Second World War than the Nazi-Soviet Pact of August 1939, and no-one is better qualified to explore its grim implications than Roger Moorhouse" (Norman Davies)

"Superbly researched and academically impeccable, yet written with all the pace of a thriller, The Devils' Alliance shines a powerful beam into one of the undeservedly least known aspects of the Second World War" (Andrew Roberts)

"Meticulous and vividly readable... Moorhouse’s grim and compelling book could not be more topical" (Sunday Telegraph)

"A highly enjoyable history written with verve and attention to detail" (Financial Times)

"Superb" (Brendan Simms Wall Street Journal)

For nearly two years the two most infamous dictators in history actively collaborated with one another. The Nazi-Soviet Pact stunned the world when it was announced, the Second World War was launched under its auspices with the invasion and division of Poland, and its eventual collapse led to the war’s defining and deciding clash.

It is a chapter too often skimmed over by popular histories of the Second World War, and in The Devils’ Alliance Roger Moorhouse tells the full story of the pact between Hitler and Stalin for the first time, from the motivation for its inception to its dramatic and abrupt end in 1941 as Germany declared war against its former partner.

Using first-hand and eye-witness testimony, this is not just an account of the turbulent, febrile politics underlying the unlikely collaboration between these two totalitarian regimes, but of the human costs of the pact, as millions of eastern Europeans fell victim to the nefarious ambitions of Hitler and Stalin.
