History (with the exception of China and India, which require distinct consideration, as standing apart) begins with Egypt, and flows down in a continuous stream, until, in the fourth century A.D., the Roman Empire, into which the ancient civilized peoples were incorporated, was broken up. Then the new nations, especially the tribes of the Germanic race, took power into their hands; Christianity was established among them; out of the chaos of elements there emerged the European nations, with their offshoots,--the peoples at present on the stage of action. Ancient history had its center in the Mediterranean. It embraced the peoples who dwelt on the shores of that sea, in the three continents, and the nations that were brought into relations with them. The Roman Empire, the final outcome of ancient history, was "the monarchy of the Mediterranean." With the breaking-up of the Empire, new races, new centers of power, a universal religion in the room of national religions, and a new type of culture and civilization, were introduced. Invaluable legacies were handed over from the past, surviving the wreck of ancient civilization. There is, however, a unity in history: the transition from the ancient to the modern era was gradual. MEDIAEVAL AND LATER MODERN HISTORY. Since the fall of the Roman Empire, there has occurred no revolution to be compared with the circumstances and results of that event. An old world passed away, and a new world began to be. Yet the student, as he travels hitherward, arrives at another epoch of extraordinary change,--a period of ferment, when modern society in Europe takes on a form widely different from the character that had belonged to it previously. The long interval between _ancient_ history and _modern_ (in this more restricted sense of thes term) is styled the Middle Ages. Its termination may be found in the fifteenth century, and a convenient date to mark the boundary-line is the capture of Constantinople by the Turks (1453). History thus divides itself into three parts:-- Part I. Ancient History, to the migrations of the Germanic Tribes (375 A.D). Part II. Mediæval History, from A.D. 375 to the Fall of Constantinople (1453). PART III. Modern History, from 1453 until the present.
