Russia’s invasion of Ukraine is one of the most important conflicts of the twenty-first century. With the start of military hostilities in 2014 also came an onslaught of propaganda, to both convince and confuse audiences worldwide about the war’s historical and ideological underpinnings. Based on extensive research drawing on tens of thousands of news articles and hundreds of pages of legal documents and internal correspondence, this book offers the first comprehensive analysis of the role of propaganda, ideology, and identity in the Russian-Ukrainian war. It argues that, despite Russia’s efforts to set up a media machine at home and abroad with eight years of propaganda legitimising Russia’s presence in eastern Ukraine, Russia never managed to vocalise a convincing alternative to Ukrainian nationhood. Instead, Russian propaganda backfired: Ukraine is now more united than ever before.
