Black cash, anonymous donors, bribery, "Cologne clique" – few areas of public life are confronted with affairs and scandals as often as politics. Given the enormous public interest and media attention directed at these issues, the way politicians and parties handle their suspected or actual misconduct is of particular importance. The megatrend towards a media society increasingly compels political actors to communicate their actions and goals to potential voters through the media, while creating an impression of transparency and credibility. The aim of this book is to explain the fundamentals of public relations (PR) in crises against this backdrop and to highlight their significance for political parties in Germany. It begins with an introduction to the basic concepts of public relations.
