The 2022 war in Ukraine has produced the biggest virtual humor archive in the history of wars. We argue that Ukrainian war humor is a form of civic activism in the name of Ukraine’s sovereignty. This civic activism is defined by resistance, solidarity, vigilance, and dedication to victory. The war humor circulates locally as well as on a global stage. It expresses the government’s positions and the people’s voices and empowers those affected by this war. Ukrainian war humor documents experiences of war realities; provides moral commentaries and emotional and aesthetic interpretations; and articulates visions for the future of Ukraine as a sovereign European state.
