Rome gathered its population from all the neighboring states. The mingling of races has always been favorable to the progress of mankind. A single race, isolating itself and receiving no new blood or impulses from without becomes stationary and fixed in all its habits and advancement ceases beyond a certain point. The men who founded Rome were, apparently, a crowd of adventurers who had resolved to found a state. After building the walls of their city and providing themselves with habitations, they were destitute of wives—a serious want which would soon leave their new city without inhabitants. They remedied it in true Roman style—by violence. They made a festival without the walls to celebrate the founding of their state, and invited their nearest neighbors, the Sabines, to take part in it. The Sabines came with their wives and daughters. At a concerted moment the young Romans each seized a young Sabine woman, and carried her off into the city; the gates were closed and each proceeded to make his captive his wife. The Sabines were powerless to prevent the deed, but they soon made war on their violent sons-in-law, and the young city would have been destroyed but for the interference of the stolen women who had become satisfied with the bold deed which gave them valiant husbands. The Sabines were induced to unite with the young state so far as to build a new city adjoining and take part in its rising fortunes. Romulus was elected king by his followers, but popular institutions were established to limit his power, under the strong instinct of vigorous organization that, from the first, characterized the new nation. The people maintained their right to make laws in conjunction with the king, and preserved a limited monarchy for 250 years. At this time the prophet Isaiah flourished in Judea, and the kingdom of Samaria was approaching extinction. 15. B. C. 747. The Chaldeans established, or revived, their dominion in Babylon, under their king, Nabonassur, and seem to have been independent of Assyria for a time, but afterward to have been brought into a qualified subjection to that enterprising monarchy. It commences authentic history in the East, so far as well ascertained dates are concerned. In that year the Chaldean astronomers or priests, first introduced the Egyptian solar year, which furnished an accurate mode of measuring time. This was about the commencement of the Sixth Olympiad. Egypt was approaching its most perfect condition under its ancient system. B. C. 743. Messenian war of 23 years—Sparta conquers Messene.
