In 1881 Leroy-Beaulieu was elected professor of contemporary history and eastern affairs at the Ecole Libre des Sciences Politiques, becoming director of this institution on the death of Albert Sorel in 1906, and in 1887 he became a member of the Academic des Sciences Morales et Politiques.
He wrote many short stories and novels, and has also contributed to the Figaro, Gaulois and Libre Parole.
In May and June 1789 he had written La France libre, which, to his chagrin, his publisher refused to print.
In 1833 the Societe biblique francaise et etran'gere was formed on wider lines; after its dissolution in 1863, many of its supporters joined the Societe biblique de France, which dates from 1864, and represents chiefly members of the Eglise libre, and kindred French Evangelicals.
A strict line of demarcation, however, remains in the mutual oath which forms the basis of the civic community in both varieties of the latter, and in the fact that the ville libre stands to its lord in the relation of vassal and not in that of an immediate possession.
