Robert von Mohl, who lived from 1799 until 1875, remains central to discussions regarding the constitutional state, having first coined the term Rechtsstaat. Throughout his career in the Kingdom of Württemberg and beyond, he navigated the complex intersections of jurisprudence, political science, and government service, shaping institutional theory during a period of significant European political transition.
Academic Career and Political Friction
Mohl’s early career was defined by his tenure at the University of Tübingen, where he served as a professor of political sciences from 1824 until 1845. His academic influence extended to Staatswissenschaften, a field encompassing political science and economics. However, his tenure ended abruptly due to explicit criticisms of local authorities, leading to his dismissal. He later transitioned to Heidelberg University in 1847 to continue his work in law.

Beyond the lecture hall, Mohl engaged deeply in the political mechanisms of his time. He served as a member of the Frankfurt Parliament in 1848, briefly acting as minister of justice. His legislative commitment continued later in life, serving in the Reichstag of the German Empire from 1874 to 1876. Additionally, he represented Friedrich I, Grand Duke of Baden, as an ambassador in Munich between 1867 and 1871.
Philosophical and Legal Contributions
Mohl distinguished his legal philosophy by advocating for the constitutional state over the prevailing police state model. This intellectual framework is evident in his seminal publications, including Die Polizei-Wissenschaft nach den Grundsätzen des Rechtsstaates and the Encyklopädie der Staatswissenschaften. His theoretical output influenced global governance, specifically impacting Japanese state philosophy during the Meiji Restoration through the interpretation of thinkers such as Kato Hiroyuki.
