We have indicated its characteristics, that is, a loss of the personality of the nations that go on to make up part of the empire and acquisition by those subject to the rights of the citizens. Afterwards, under a new imperial domination, comes the political and social regime that it had at the beginning. The chart clearly indicates the phases of the social evolutions that begin by a first one, that has a duration of four centuries, during which the nation�s gradual progress arises under the domination of the imperial aristocracy. There follows a second phase in which power is taken over by the wealthy aristocracy until the middle class intervenes. � This phase of wealth and democracy aristocracy, has a duration of two and one-half centuries and, therewith, ends the first era of great fractionation that then had a total duration of six and one-half centuries. Then comes the phase of anarchy, civil war or decadence of democracy, and the cities, free until now, fall under the hegemony of an imperial nucleus. This federal phase has a duration of two centuries.� The unitary absolutist phase follows with the ascending process of the centuries, after which the decadence of the regime begins. A central power debilitation process is produced and, finally, disintegration comes and the nations of the empire remain under the domination of the new imperial nucleus that will subject the old citizens to the regime of servitude and slavery with which the century ends. WORLD PROSPECTIVE OF THE XXI CENTURY I.- a) From remote times, currents of culture are produced that are displaced over the surface of the earth, originating civilizations of diverse grades of advance, among others, some as advanced as the present ones and that, at the same time, develop great unification nuclei, empires or great nations. In addition to the discovery of the great prehistoric civilizations, it should be added that the constitution of present-day skulls, is analogous to those of 400,000 years ago B.C., and so the utilization of fire, the date of which goes back to 250,000 B.C.� In this sense, we should immediately study and research what man did in that space of time.� With the results of the excavations and works of Schliemann (Archeologist), Homer and the characters of The Iliad, stopped belonging to mythology and now are part of Greek history.� Likewise, the works of Evans (English Archeologist), the German Egyptologist, Lepsius, the French Egyptologist, Mariette and the English Archeologist and Egyptologist, Petrie, constitute a great headway. b) Referring to the development of Assyrian, Babylonian, Egyptian and Cretan cultures, note the proportions and grandeur of their constructions, superior to others in any manner of comparison.
