[28] Cf. de Goeje, _Mem. sur les Carmathes de Bahraïn et les Fatimides_ (Leide, 1886). In this connection we may observe that in our own days the Dutch, with de Goeje at their head, have rendered far greater services in the elucidation of the history and geography of the Arabs than the schools of any of the great nations. [Illustration] HISTORY IN OUTLINE OF PARTHIANS, SASSANIDS, AND ARABS We turn back now to the scene of the earlier history, turning back in time also. The events of three great empires will pass quickly before the view, the period of time involved being more than seventeen hundred years. The territories occupied by the peoples under consideration were wide, and the peoples themselves successively dominated the eastern world, and contested supremacy there with Rome. Of the Parthians and Sassanids it must be said that, while important in holding Rome back, they had otherwise an inconsiderable influence in the West; moreover, Rome could not have retained the Orient even had she conquered it. As regards the culture influence of the Parthians and Sassanids in Europe, this was virtually _nil_. The case is quite different when we come to the Arabs. Here was a race which not only became dominant in the East, but seriously threatened to overthrow and supplant the entire civilisation of Europe; and which, foiled in this, retained supremacy in the East and developed an indigenous culture that powerfully influenced all Christendom. It must be understood that the relations between the Parthians, Sassanids, and Arabs is geographical and chronological rather than ethnological. The Parthians were overthrown by the Sassanids, and the Sassanids by the Arabs. The three peoples successively ruled over similar territories, and their histories may advantageously be considered in sequence; but it will be understood that they represented different races and bore to one another merely the relation of the conquered to the conqueror. An outline of the history of Armenia is appended, to give completeness to the subject, much as we gave chronologies of various other minor nations of Western Asia in a previous volume. THE PARTHIAN EMPIRE (250 B.C.-228 A.D.) B.C. During the reign of the Seleucid king Antiochus II, Diodotus, viceroy of Bactria, seizes the northeastern provinces and assumes the title of king. The formation of this kingdom is not agreeable to the chiefs of the desert tribes who, under the Seleucid rule, have never felt direct control, and some of them migrate into Parthia. Among them are two brothers, Arsaces and Tiridates, of the Parnians. In a quarrel which arises between them and Pherecles, presumably satrap of Astauene, the latter is slain and Arsaces is proclaimed king in Asaak, northwest of Parthia. 250 Foundation of an independent monarchy by =Arsaces I=. Antiochus, on account of civil and foreign wars, is unable to proceed against Arsaces.
