The chapter analyzes systemic corruption in Ukraine since its independence. This is the result of historical legacies from the Soviet era, the transformation dynamics of the 1990s and the actions of political and economic actors. Unlike in authoritarian regimes such as Russia or Belarus, Ukraine has developed a system with several competing centers of power, characterized by various oligarchic groups and regional clans. Corruption permeates all levels of government. It manifests itself in a widespread system of dependencies and favors, in the targeted generation of excessive profits from state resources and in the close links between the business world and politics. Despite several attempts at reform, particularly after the Orange Revolution in 2004 and the Euromaidan in 2014, the system has proven to be surprisingly stable. Under President Zelensky and especially since the Russian war of aggression in 2022, new reform dynamics have emerged. The power of the oligarchs appears to have been weakened and the EU accession process is increasing pressures for reform. Nevertheless, structural problems remain, as the selective application of anti-corruption measures shows.
