been pointed out before, and is fairly obvious. Thus Mougins-Roquefort, a French lawyer, in his book De la Solution Juridique des Conflits Internationaux (1889), observes that in the days of the Roman Empire, when there was only one civilized state, any system of international relationships was impossible, but that as soon as we have a number of states forming units of international society there at once arises the necessity for a system of international relationships, just as some system of social order is necessary to regulate the relations of any community of individuals.
In England, a small and compact country, this process was completed at a comparatively early date. In France it was not until the days of Louis XV (in 1756) that the "last feudal brigand," as Taine calls the Marquis de Pleumartin in Poitou, was captured and beheaded.
