In communist Eastern Europe the churches were often a focus for opposition to communism, and in the immediate post-communist period the churches often played a key role in fostering national cohesion, in promoting a conservative political agenda, sometimes in formal alliances with political parties, and in rewriting national narratives to eliminate or revise communist versions of such narratives. These activities, which are implicitly conservative and nationalistic, are not naturally in step with European integration. This book explores the relationship between religion and politics in post-communist Europe, focusing especially on the degree to which religion, and religious involvement in politics, encourage Euroscepticism. The book, which covers a range of East European countries, shows how religion is very important as a political force, how religion’s contribution to Euroscepticism varies between countries, and how in some circumstances, especially when a religious-based party is in power and has to deal with Brussels, religion can favour European integration. The book includes coverage of Catholic, Orthodox and Muslim countries, and includes discussion of how religious organisations, which often engage in lobbying in Brussels, relate to the European Union itself.
