The Western understanding of what happened in Ukraine during World War II has been shaped by historical and ideological constructs created in the Kremlin. The Ukrainian specificity has been dissolved in the concept of the “great victorious Russian people” and distorted by attempts to equate Ukrainian nationalists to German Nazis, while the occupation and colonization of Ukraine by Russian Bolsheviks in the 1920s and 1930s has widely been ignored or artificially silenced. In her Four Essays on World War II, Olena Stiazhkina inscribes the Ukrainian history of the war into a wider European and world context. Amongst other aspects, she analyzes the mobilization measures on the eve of the war, reconsidering Soviet narratives. Scrutinizing the social and political processes initiated by the Bolshevik leadership in the 1920s and 1930s, Stiahhkina concludes that mobilization and militarization were integral parts of Soviet power policy. The Soviet and contemporary Russian narratives about World War II have been used to justify the Kremlin’s policies towards democratic countries. Today, Russia remains deeply engaged in the falsification of the past, which underpins the claims of the so-called “Russian World” and the ongoing war against Ukraine. Olena Stiazhkina’s book promotes a new, historically adequate understanding of what happened in Ukraine before, during, and after World War II.
