Only conquering monarchs with whole nations as prisoners could have compassed such results. This, indeed, was one of the great objectives of war in these early times. It was the amassing of a great population for manual labour and the creation of new centres of civilization and trade. Thus it was that the peoples of Western Asia--Egyptians, Israelites, Jews, Ph[oe]nicians, Assyrians, Babylonians, and even Greeks--were transported over vast distances by land, and a movement given to the human race in that part of the world which has infinitely complicated the science of ethnology. The peopling of Canada by the French, of North America by the English, of Brazil by the Portuguese, of Argentina and Chile by Spaniards and Italians, is perhaps a more comprehensive process in the distribution of humanity and more permanent in its character. But ancient compulsory movement, if not as extensive as modern voluntary emigration, was at least wholesale, and it led to the distribution of people in districts which would not naturally have invited them. The first process in the consolidation of a district, or satrapy, was the settlement of inhabitants, sometimes in supercession of a displaced or annihilated people, sometimes as an ethnic variety to the possessors of the soil. Tiglath Pileser was the first Assyrian monarch to consolidate the Empire by its division into satrapies. Henceforward the outlying provinces of the dominions were convenient dumping places for such bodies of captives as were not required for public works at home.
Nothing would be more natural than that Sargon should deport a portion of the Israelitish nation to colonize his eastern possessions towards India, just as Darius Hystaspes later employed the same process to the same ends when he deported Greeks from the Lybian Barke to Baktria. There is nothing more astonishing in the fact that we should find a powerful people claiming descent from Israel in Northern Afghanistan than that we should find another people claiming a Greek origin in the Hindu Kush.
Nor was the importance of peopling waste lands and raising up new nations out of well-planted colonies overlooked ten centuries before Christ any more than it is now. Then it was a matter of transporting them overland and on foot to the farthest eastern limits of these great Asiatic empires. Always east or south they tramped, for nothing was known of the geography of the North and West. Eastwards lay the land of the sun, whence came the Indians who fought in the armies of Darius, and where gold and ivory, apes and peacocks were found to fill Ph[oe]nician ships. To-day it is different. The peopling of the world with whites is chiefly a Western process. Emigrants go out in ships, not as captives, but almost equally in compact bodies--the best of our working men to Canada, and many of the best of our much-wanted domestic servants to South Africa. It is a perpetual process in the world's economy, and perhaps the chief factor in the world's history; but in the old, old centuries before the Christian era it was necessarily a land process, and the geographical distribution of the land features determined the direction of the human tide. Some twenty years before the fall of Samaria and the deportation of the ten tribes of Israel, Tiglath Pileser had effected conquests in Asia which carried him so far east that he probably touched the Indus. Why he went no farther, or why Alexander subsequently left the greater part of the Indian peninsula unexplored, is fully explicable on natural grounds, even if other explanations were wanting.
