Comparative political science is a sub-discipline of political science, whose self-understanding is derived from the comparative method. Often, the comparative method in political science is the only viable way to make generalizable statements about socio-political processes. However, a systematic comparison is demanding and various factors must be considered in order to apply the comparative method profitably in political science. This textbook represents the most comprehensive German-language monograph on comparative political science. The author provides an in-depth overview of the subject areas, logic, theories, and methods of comparative political science. The application-oriented introduction offers the opportunity to understand the basic principles of comparative political science.
