Abstract: | The primary focus of the historian and political scientist Friedrich Christoph Dahlmann (1785–1860) was the importance of constitution. Dahlmann perceived the concept of constitution not as a written legal document but rather, following the thinking of Aristotle, as the good order of a political community. This constitutional concept was Dahlmann’s guide in dealing with three particular political challenges: the quest for Schleswig-Holstein’s unity with the German nation, his leadership in the protest of seven Göttingen professors against the constitutional coup of the new king of Hanover in 1837, and his contribution to the German Constitution of 1849. Dahlmann’s main legacy is the importance of integrating constitutional topics into today’s research and teaching of politics and polity. |
