There is, however, still another kind of empire. In it the superior authority is not a people, but an individual. He is called an emperor, and his family a dynasty. His authority is bestowed, as the present German Emperor said at Königsberg in 1910, not by "parliaments, and meetings, and decisions of the peoples, but by the grace of God alone." He is "a chosen instrument of Heaven," to speak with the same high authority, and "goes his way without regard to the views and opinions of the day." An emperor, thus defined, is not properly a part of his state at all. He stands outside of it, and is equal or superior to it. He is a state unto himself; and his jurisdiction is not domestic but imperial, in that he exercises dominion over another state. _L'état c'est moi_ is an imperfect definition of this kind of empire, however; for it presumes the absence of political organization and activity among the subjects of the emperor. It presumes the permanency of the condition of absolute surrender (_deditio_) which, with the Romans, prefaced the work of restoration--the reëstablishment of civil rights within an enlarged state. In actual experience, moreover, a complete autocracy never exists. The will of every emperor is bound by the legislation which he has himself enacted, or accepted with the throne from his predecessor. If responsible to nothing else, he is responsible to his own past. He may withdraw his charters: he cannot violate them with impunity. * * * * * The policy by which a people or an autocrat acquires and maintains an empire, we call imperialism. The term is, of course, a legacy from Rome--a mute witness to the peculiar importance of the Roman empire in the history of state-building. And, I suppose, it is the policy of Rome that we think of most instinctively when we allude to imperialism. This is by no means an accident. For not simply the type, but also many of the most noteworthy varieties of this kind of policy, are found in the experience of the Romans; and the course of political progress has been such that in the triumph of Rome imperialism reached its logical issue more closely than either before or since in the history of the world.
