The Thule-Seminar is a far-right nationalist organization with strong Neopaganist roots based in Kassel, Germany. It was founded in 1980 by Pierre Krebs, essentially as the German branch of GRECE. Sometimes described as a think tank or "party of the mind", its name alludes to the Thule Society, one of the organizations that facilitated the rise of the Nazis and provided some of the intellectual cadre for the latter.
