The manuscript analyzes negative developments in Bulgarian and Romanian politics in the aftermath of the two countries’ accession to the European Union, with a special focus on the worsening corruption problem, the destabilization of previously coherent normative frameworks, and the reversal of processes of state building. It also explores the main characteristics of a novel form of elite behavior, post-accession hooliganism, which began to emerge as soon as Bulgarian and Romanian political leaders felt strong and confident enough to disregard the demands of their West European counterparts.
