During the 1970s, Rougier formed a second controversial political alliance: with the Nouvelle Droite of the French writer Alain de Benoist. Rougier's long-standing opposition to Christianity, together with his conviction that "the West" possesses a pragmatically superior "mentalité" to those of other cultures, aligned closely with the views of this movement. Benoist reissued and wrote prefaces to several of Rougier's earlier works, and in 1974 Benoist's think tank GRECE published an entirely new book by Rougier: "Le conflit du Christianisme primitif et de la civilisation antique".
