This gave opportunity to the growing powers of the West. Alexander is scarce gone ere we hear Carthage boasting that the Mediterranean is but a private lake in her possession. She rules all Western Africa and Spain, Sardinia and Corsica. She masters the Greeks of Sicily, against whom Athens failed. Rome is compelled to sign treaties with her as an inferior. THE GROWTH OF ROME Rome was only husbanding her strength; the little republic of B.C. 510 had grown much during the two centuries of Grecian splendor. Her people had become far better fitted for conquest than their eastern kinsmen. It is presumable that here too it was the difference of surroundings which had differentiated the race. The ancient Etrurian (non-Aryan) civilization on which the Latins intruded, was apparently more advanced than their own. For centuries their utmost prowess scarce sufficed to maintain their independence. Thus it was not possible for them to become too self-satisfied, to stand afar off and look down on their neighbors with Grecian scorn. The _ego_ was less prominently developed; the necessity of mutual dependence and united action was more deeply taught. Their records display less of brilliancy, but more of patient persistency, than those of Greece, less of spectacular individualism, more of truly patriotic self-suppression. In Rome, even more than in Sparta, the "State" was everything. During the early days men found their highest glory in making their city glorious; their proudest boast was to be "citizens of Rome." To trace the slow steps by which the tiny republic grew to be mistress of all Italy would take too long. She settled her internal difficulties as all such difficulties must be settled, if the race is to progress; that is, she became more democratic.[10] As the lower classes advanced in knowledge and intelligence they insisted on a share of the government. They fought their way to it. They united Rome, mastered the other Latin cities, and admitted them to partnership in her power. She conquered the Etruscans and the Samnites. For a moment we find her almost overwhelmed by an inroad of the wild Celtic tribes from the forests of Central Europe;[11] but, fortunately for her, the other Italian states were equally crushed. It was weakness against weakness, and the Romans retained their foremost place.
