This is the companion volume to Political Catholicism in Europe 1918-1945 . Christian Democratic (CD) parties became the dominant political force in post-war Western Europe, and the European People's Party is currently the largest group in the European Parliament. CD parties and political leaders like Adenauer, Schuman and De Gasperi played a particularly important role in the evolution of the 'core Europe' of the EEC/EC after 1945. This book, for the first time, reveals the roles of the CD parties in postwar Europe, systematically and from a pan-European perspective. All country chapters address the same questions about the parties' membership and social organization; their economic and social policies; and their European and international policies during the Cold War. The book also includes two survey chapters setting out the international political context for CD parties and comparing their postwar development, and two chapters on their transnational party cooperation after 1945. This volume (and its companion volume) are research based and will be accessible to undergraduate and graduate students. As Christian Democratic parties are the least researched compared with Socialist or Communist parties, and with no CD parties in the US or the UK, hardly any useful literature exists in English which can be used on twentieth century and postwar European history courses, or more specialised history or country courses. This book therefore fills a significant gap in postwar European history, and will prove valuable to researchers and students of European studies, politics and history.
