The location of Rome, on the Tiber at a point where navigation for sea-going vessels terminated and where an island made easy the passage from bank to bank, marked it as a place of commercial importance. It was at the same time the gateway between Latium and Etruria and the natural outlet for the trade of the Tiber valley. Furthermore, its central position in the Italian peninsula gave it a strategic advantage in its wars for the conquest of Italy. But the greatness of Rome was not the result of its geographic advantages: it was the outgrowth of the energy and political capacity of its people, qualities which became a national heritage because of the character of the early struggles of the Roman state. Although it is very probable that the historic population of Rome was the result of a fusion of several racial elements—Latin, Sabine, Etruscan, and even pre-Italian, nevertheless the Romans were essentially a Latin people. In language, in religion, in political institutions, they were characteristically Latin, and their history is inseparably connected with that of the Latins as a whole. III. THE EARLY MONARCHY *The tradition.* The traditional story of the founding of Rome is mainly the work of Greek writers of the third century B. C., who desired to find a link between the new world-power Rome and the older centers of civilization: while the account of the reign of the Seven Kings is a reconstruction on the part of Roman annalists and antiquarians, intended to explain the origins of Roman political and religious institutions. And, in fact, owing to the absence of any even relatively contemporaneous records (a lack from which the Roman historians suffered as well as ourselves) it is impossible to attempt an historical account of the period of kingly rule. We can improve but little on the brief statement of Tacitus (i, 1 _Ann._)—“At first kings ruled the city Rome.”
