In the aftermath of the violent Revolution of Dignity (2013/2014) and the subsequent war in Donbas (2014–), a heroic story about the new beginning of a “united, Ukrainian nation” began to emerge. Shaping this new narrative are new museum projects devoted to Ukraine’s developing history. This article examines the process of these new institutions’ formation, the content of created exhibitions, and the activities conducted therein. It focuses on the role of the museums in activating, unifying, and integrating both the Ukrainian national community and civil society. This article is based on a qualitative analysis of materials collected during seven research stays in Ukraine, from June 2017 to August 2019, and focuses on four cases–Ukraine’s First ATO Museum in Dnipro; the Museum of the Heavenly Hundred in Ivano-Frankivsk; the Ukrainian East exhibition in the National Museum of the History of Ukraine in the Second World War in Kyiv; and a project of the Museum of the Revolution of Dignity in Kyiv. The examined institutions are presented not only as places for gathering artifacts but also as laboratories of civic activism, participation, and dialogue.
