The "Historically-Political Communications" of the Konrad Adenauer Foundation serve as a forum for research and presentations on the history of Christian Democratic movements and parties in Germany and Europe. In volume 30, Agilolf Kesselring and Thorsten Loch discuss Konrad Adenauer's "Honor Declaration" for members of the Wehrmacht from December 3, 1952. Rudolf Uertz addresses the early economic and social programmatic aspects of the CDU, while Benedikt Brunner explores the intellectual development of former Bundestag President Hermann Ehlers and his role in founding the Protestant Working Group of the CDU/CSU. Hanns Jürgen Küsters describes the lessons CDU politician Kai-Uwe von Hassel learned from his long-term experiences. Josefine Preissler investigates the early history of the Weikersheim Castle Study Center as an attempt at a conservative "think tank," and Rebecca Schröder examines the role of the Archive for Christian Democratic Politics as the European political memory of Christian Democracy. Additionally, contributions from the conference "Helmut Kohl and the Churches" by Markus Raasch, Jürgen Plöhn, Michael Borchard, and Antonius Liedhegener are included, as well as a presentation on the financing of German reunification by the then Federal Minister Theo Waigel and his State Secretary Walther Otremba.
