This study examines the indispensable role of anti-corruption reforms in Ukraine’s post-war reconstruction, and its moves towards a resilient and prosperous future within Europe. Through a comparative analysis of post-war reconstruction cases, it elucidates that Ukraine’s distinct situation, marked by relative stability and a unified society, yet a critical demographic situation, calls for an unparalleled enactment of profound anti-corruption measures. Furthermore, the study underscores the importance of such reforms to accelerate Ukraine’s European Union integration process, and of anti-corruption reforms to be, in turn, accelerated by this integration process.
