The historian, political teacher and constitutional politician Friedrich Christoph Dahlmann (1785-1860) was the most prominent among the "political professors" before and during the revolution of 1848. Even as a professor in Kiel, Dahlmann advocated the indivisibility of the two duchies of Schleswig and Holstein made unpopular with the Danish rule. In Göttingen, he led the protest of seven professors against the coup d'état by the Hanoverian king. As Bonn professor, Dahlmann was elected to the Frankfurt National Assembly and was one of the fathers of the Paulskirche constitution, in the tradition of which the Bonn Basic Law stands. This volume pays tribute to the interrelationship between Dahlmann's academic learning, moral convictions and political commitment. His contributions are not only relevant to the history of the university and science, they also deal with the topicality of Dahlmann's teachings.
