SummaryThis article sheds light on intellectual politics under Nazism by looking at a crucial shift in the field of Hobbes studies that was marked in a congress celebrating the three hundred and fiftieth anniversary of Thomas Hobbes's birth, organised in Kiel, 1938. Before the congress, the decisive voice in Hobbes studies had for almost fifty years been that of Kiel University professor Ferdinand Tönnies. Tönnies was purged from the university upon the Nazi seizure of power in 1933 and died three (...) years later. At the opening of the Hobbes congress in Kiel, its convener, Cay von Brockdorff, declared that the phase of Hobbes studies shaped by Tönnies was ending and that a new phase, represented by Paul Ritterbusch and Carl Schmitt, had emerged. Against the background of a long tradition of Hobbes studies in Kiel, this article summarises Tönnies's contribution to Hobbes studies; analyses organisation and proceeedings of the congress, paying special attention to politico-theoretical disagreements between Ritterbusch and Schmitt and to von Brockdorff's exploitation of their rivalry; and contextualises Schmitt's interpretation of Hobbes published in the aftermath of the congress.
