Specific country chapters address key questions about the parties' membership and social organization; their economic and social policies; and their European and international policies at a time of increasing national and ethnic conflict, and the book includes two survey chapters explaining the origins of political catholicism in 19th century Europe and comparing the parties' interwar development, and two chapters on transnational party contacts. Along with its companion volume, Christian Democracy in Europe Since 1945, also published in 2004, students will have an abundandce of information to guide them through their studies on this fascinating subject.
