ZEI Discussion Paper C 272 / 2022

Europäische Parteien als Antrieb für die europäische Integration? by Merit Thummes

Political parties at the European level are still largely unknown to most citizens in the European Union, even 30 years after their inclusion in primary law by the Maastricht Treaty. The introduction of these so-called Europarties was linked the mission of forming a European awareness and expressing the political will of the union’s citizens. It was accompanied by the hope that the parties could be a driving force for European integration, especially regarding a European society. So far, the Europarties have largely failed to fulfill this task. After giving an overview on the current situation of parties at the European level, the article presents proposals for reform and possible opportunities that would arise from party politicization at the European level.

ZEI Discussion Paper C 271 / 2022

EU enlargement into the Western Balkans: a gloomy prospect gets gloomier. by Milenko Petrovic

Nearly two decades after the EU stated in the 2003 Thessaloniki agenda that all the Western Balkan states ‘will be an integral part of a united Europe’, Croatia is the only one of them to have succeeded in reaching this goal. Of the remaining Western Balkan states, only Montenegro and Serbia have opened the accession negotiations with the EU, albeit with very slim prospects to close all 30+ negotiation chapters any time in the foreseeable future. The others are further behind; they are either still waiting to open accession negotiations (as is the case with the other two official candidates for EU membership – Albania and Macedonia) or even achieve full candidate status (Bosnia and Herzegovina and Kosovo). Facing post-2004/07 ‘enlargement fatigue’ and numerous internal problems and crises since the late 2000s/early 2010s, the EU’s political elite and wider public, particularly in its core member states, seem to have lost any interest in further enlargement and in assisting the Western Balkan hopefuls to become part of ‘a united Europe’. Prospects for acceleration of any Western Balkan state’s accession process in the 2020s are very slim.
