The Carthaginians were the great ethnic offshoots of Phoenicia in the western part of the ancient world. It would not be in place here to inquire what motives led these wanderers away from their Asiatic home, or what was the nature of the settlement which they made. They left Tyre and founded the celebrated city of Carthage, on a spot where an ancient colony from Sidon previously existed.[6] Carthage very early--indeed, we might almost say, at the start--assumed a higher character than any previous colony or city of Phoenicia. It soon became, in fact, an independent political power. It began to flourish at a time when Tyre and Sidon were on the decline, and when these once great cities had become tributary to Asiatic potentates. The Carthaginians became first the protectors, and soon afterward, the masters of all the ancient Phoenician colonies scattered over the western world. Nor did they stop here; they became a warlike and conquering empire. The political misfortunes of their mother country increased, by almost uninterrupted immigration, the number of poor free citizens in Carthage, as well as in other seacoast cities now Punic, though once Phoenician--many of them, indeed, having a numerous Libyo-Phoenician population. This surplus the Carthaginians sent off as colonists into the interior of Libya, where they founded smaller cities or settled as agriculturists among the native population, whose lands, in many instances, were assigned to the new-comers. The Carthaginian oligarchy soon began to oppress and look with contempt upon the ancient Phoenicians, Libyo-Phoenicians and Libyans. In process of time, the new colonists mixed with the ancient populations, and all were soon equally sufferers from oppressive tributes and exactions. The common hatred of these various populations against the oligarchy, which frequently led to revolt, was a powerful aid to the Numidian kings and to the Romans in their efforts to crush haughty Carthage. The great Carthaginian oligarchs and slaveholders extended and perfected what the Phoenicians perhaps only began. They acquired in various ways vast landed estates, and oppressed and impoverished the tributary colonists and small freeholders by grievous exactions; they seized their homesteads, and finally reduced them to serfdom and slavery. Toward the decline of Carthaginian power, such estates were mostly cultivated by slaves; and these slaves--those in the country as well as those in the cities--were either Libyo-Phoenicians and Libyans, or belonged to Asiatic and European races--the unhappy individuals being either bought or taken as prisoners of war. The subdued and slave populations were as mixed as the Carthaginian armies, which, in Africa especially, contained a vast number of negroes--thus presenting an antetype of the French Turcos.
