+36.+ Our narrative now returns to Hasdrubal, whom we left in command of the Carthaginian forces in Iberia. After eight years command in that country, he was assassinated in his own house at night by a certain Celt in revenge for some private wrong. Before his death he had done much to strengthen the Carthaginian power in Iberia, not so much by military achievements, as by the friendly relations which he maintained with the native princes. Now that he was dead, the Carthaginians invested Hannibal with the command in Iberia, in spite of his youth, because of the ability in the conduct of affairs, and the daring spirit which he had displayed. He had no sooner assumed the command, than he nourished a fixed resolve to make war on Rome; nor was it long before he carried out this resolution. From that time forth there were constant suspicions and causes of offence arising between the Carthaginians and Romans. And no wonder: for the Carthaginians were meditating revenge for their defeats in Sicily; and the Romans were made distrustful from a knowledge of their designs. These things made it clear to every one of correct judgment that before long a war between these two nations was inevitable. [Sidenote: Social war, B.C. 220-217.] +37.+ At the same period the Achaean league and King Philip, with their allies, were entering upon the war with the Aetolian league, which is called the Social war. Now this was the point at which I proposed to begin my general history; and as I have brought the account of the affairs of Sicily and Libya, and those which immediately followed, in a continuous narrative, up to the date of the beginning of the Social and Second Punic, generally called the Hannibalic, wars, it will be proper to leave this branch of my subject for a while, and to take up the history of events in Greece, that I may start upon my full and detailed narrative, after bringing the prefatory sketch of the history of the several countries to the same point of time. For since I have not undertaken, as previous writers have done, to write the history of particular peoples, such as the Greeks or Persians, but the history of all known parts of the world at once, because there was something in the state of our own times which made such a plan peculiarly feasible,—of which I shall speak more at length hereafter,—it will be proper, before entering on my main subject, to touch briefly on the state of the most important of the recognised nations of the world.
