Invisible University for Ukraine (IUFU) is an initiative of Central European University that began in Spring 2022, only months after Russia's full-scale invasion of Ukraine. Since that time, nearly 1,000 Ukrainian students have taken online and on-site courses taught by hundreds of faculty from across Europe and beyond. The program's objective is to help sustain intellectual growth in the midst of incredible hardships, with coursework designed to mitigate the effects of the war on students' academic development and provide a framework to push back against autocracy. This volume recognizes the initiative of IUFU's organizers and its students, describes their work to sustain democracy, and outlines their innovative educational model developed in the face of ongoing war. For this important work, they are the recipients of the 2024 Brown Democracy Medal from the McCourtney Institute for Democracy.
