Great changes were taking place in the ancient world during the period in which Assyria rose into prominence and suddenly suffered decline. These were primarily due to widespread migrations of pastoral peoples from the steppe lands of Asia and Europe, and the resulting displacement of settled tribes. The military operations of the great Powers were also a disturbing factor, for they not only propelled fresh movements beyond their spheres of influence, but caused the petty States to combine against a common enemy and foster ambitions to achieve conquests on a large scale. Towards the close of the Eighteenth Dynasty of Egypt, of which Amenhotep III and Akhenaton were the last great kings, two well-defined migrations were in progress. The Aramaean folk-waves had already begun to pour in increasing volume into Syria from Arabia, and in Europe the pastoral fighting folk from the mountains were establishing themselves along the south-eastern coast and crossing the Hellespont to overrun the land of the Hittites. These race movements were destined to exercise considerable influence in shaping the history of the ancient world. The Aramaean, or Third Semitic migration, in time swamped various decaying States. Despite the successive efforts of the great Powers to hold it in check, it ultimately submerged the whole of Syria and part of Mesopotamia. Aramaean speech then came into common use among the mingled peoples over a wide area, and was not displaced until the time of the Fourth Semitic or Moslem migration from Arabia, which began in the seventh century of the Christian era, and swept northward through Syria to Asia Minor, eastward across Mesopotamia into Persia and India, and westward through Egypt along the north African coast to Morocco, and then into Spain.
