The Groupement de recherche et d'études pour la civilisation européenne ("Research and Study Group for European Civilization"), also known by its French acronym GRECE (French for "Greece") is an ethnonationalist think-tank, founded in 1968 by the journalist and writer Alain de Benoist.
GRECE distinguishes itself from other traditionalist conservative organizations in displaying specific interest for Germanic and Nordic cultures, rejection of Christianity and monotheism, and advocating neopaganism.
GRECE was created in January 1968 by forty nationalist activists coming from movements such as Europe-Action, the review and the circle organized around Dominique Venner and Jean Mabire, the Federation of Nationalist Students (FEN), the National Movement of Progress (MNP) and the Rassemblement européen pour la liberté (REL). Alain de Benoist was among the founders, who intended to create an intellectual think-tank to influence French conservative politics. A number of journalists were members or sympathisers of the GRECE (such as the Italian journalist Giorgio Locchi), writing in the reviews Éléments and Nouvelle École.
Several GRECE members founded the éditions Copernic in September 1976, which published writings of authors seen as "precursors", such as Louis Rougier, Oswald Spengler or Julius Evola. GRECE favorized contact with elite circles by organizing conferences and meetings. It also partly funded circles which revolved around itself, such as the Pareto circle at Sciences-Po, the Galilei circle in Dijon, the Jean Médecin circle in Nice, the Henry de Montherlant circle in Bordeaux, CLOSOR (Comité de liaison des officiers et sous-officiers de réserve, a military circle), GENE (Groupe d'études pour une nouvelle éducation, Study Group For a New Education), etc. GRECE members entered in Valeurs Actuelles and Le Spectacle du monde, French magazines owned by Raymond Bourgine, a conservative reporter and politician.
