The history of Italy falls into two main sections: (1) its internal history down to its union under the leadership of the Latin stock, and (2) the history of its sovereignty over the world. Under the first section, which will occupy the first two books, we shall have to set forth the settlement of the Italian stock in the peninsula; the imperilling of its national and political existence, and its partial subjugation, by nations of other descent and older civilization, Greeks and Etruscans; the revolt of the Italians against the strangers, and the annihilation or subjection of the latter; finally, the struggles between the two chief Italian stocks, the Latins and the Samnites, for the hegemony of the peninsula, and the victory of the Latins at the end of the fourth century before the birth of Christ--or of the fifth century of the city. The second section opens with the Punic wars; it embraces the rapid extension of the dominion of Rome up to and beyond the natural boundaries of Italy, the long status quo of the imperial period, and the collapse of the mighty empire. These events will be narrated in the third and following books. Notes for Book I Chapter I 1. The dates as hereafter inserted in the text are years of the City (A.U.C.); those in the margin give the corresponding years B.C. CHAPTER II The Earliest Migrations into Italy Primitive Races of Italy We have no information, not even a tradition, concerning the first migration of the human race into Italy. It was the universal belief of antiquity that in Italy, as well as elsewhere, the first population had sprung from the soil. We leave it to the province of the naturalist to decide the question of the origin of different races, and of the influence of climate in producing their diversities. In a historical point of view it is neither possible, nor is it of any importance, to determine whether the oldest recorded population of a country were autochthones or immigrants. But it is incumbent on the historical inquirer to bring to light the successive strata of population in the country of which he treats, in order to trace, from as remote an epoch as possible, the gradual progress of civilization to more perfect forms, and the suppression of races less capable of, or less advanced in, culture by nations of higher standing.
