The conceptual history of politics in post-WWII (West-) Germany is connected to the history of academic political science. From the Bundestag plenary debates (beginning in September 1949) both the controversies on the political science itself and the contributors of both contemporary scholars and the ‘classics’ of the understanding of politics can be studied. The digitalisation of parliamentary debates opens up new chances for conceptual research in this regard. The article studies the conceptual commitments in the use of the discipline titles (Politikwissenschaft, Politische Wissenschaft, Politologie, Politikforschung, Politische Theorie, also political science) and actors (Politologe, Politikprofessor, Politstudent etc), and looks at who is mentioned in debates, for example, political scientists in early West Germany (Dolf Sternberger, Theodor Eschenburg, Wilhelm Hennis), and political theorists (Max Weber, Carl Schmitt, Hannah Arendt), Formulae from Weber’s Politik als Beruf seem to be most frequently evoked in the Bundestag.
