Young Republic League
The Young Republic League (, LJR) was a French political party created in 1912 by Marc Sangnier, in continuation of "Le Sillon", Sangnier's Christian social movement which was disavowed by the Pope Pius X (1835–1914). The LJR supported "personalist" Socialism, on the model of Emmanuel Mounier's theory of personalism. The Abbé Pierre was member of the party for a short time after leaving the MRP. Members of the LJR later joined the Union of the Socialist Left, the first movement including both Marxists and Social Christians.
