INTRODUCTION
To the First Olynthiac Oration
THE former oration (The First Philippic) does not appear to have had any considerable effect. Philip had his creatures in the Athenian assembly, who probably recommended less vigorous measures, and were but too favorably heard. In the meantime, this prince pursued his ambitious designs. When he found himself shut out of Greece, he turned his arms to such remote parts as he might reduce without alarming the states of Greece: and, at the same time, he revenged himself on the Athenians, by making himself master of some places which they laid claim to. At length his success emboldened him to declare those intentions which he had long entertained secretly against the Olynthians.
Olynthus (a city of Thrace, possessed by Greeks originally from Chalcis, a town of Euboea, and colony of Athens) commanded a large tract called the Chalcidian region, in which there were thirty-two cities. It has risen by degrees to such a pitch of grandeur, as to have frequent and remarkable contests both with Athens and Lacedaemon. Nor did the Olynthians show great regard to the friendship of Philip when he first came to the throne, and was taking all measures to secure the possession of it; for they did not scruple to receive two of his brothers by another marriage, who had fled to avoid the effects of his jealousy; and endeavored to conclude an alliance with Athens against him, which he, by secret practices, found means to defeat. But as he was yet scarcely secure on his throne, instead of expressing his resentment, he courted, or rather purchased, the alliance of the Olynthians, by the cession of Anthemus, a city which the kings of Macedon had long disputed with them, and afterward by that of Pydna and Potidaea, which their joint forces had besieged and taken from the Athenians. But the Olynthians could not be influenced by gratitude towards such a benefactor. The rapid progress of his arms and his glaring acts of perfidy alarmed them exceedingly. He had already made some inroads on their territories, and now began to act against them with less reserve. They therefore despatched ambassadors to Athens, to propose an alliance, and request assistance against a power which they were equally concerned to oppose.
Philip affected the highest resentment at this step; alleged their mutual engagements to adhere to each other in war and peace; inveighed against their harboring his brothers, whom he called the conspirators; and, under pretence of punishing their infractions, pursued his hostilities with double vigor, made himself master of some of their cities, and threatened the capital with a siege.
In the mean time, the Olynthians pressed the Athenians for immediate succors. Their ambassadors opened their commission in an assembly of the people, who had the right either to agree to or to reject their demand. As the importance of the occasion increased the number of speakers, the elder orators had debated the affair before Demosthenes arose. In the following oration, therefore, he speaks as to a people already informed; urges the necessity of joining with the Olynthians, and confirms his opinion by powerful arguments; lays open the designs and practices of Philip, and labors to remove their dreadful apprehensions of his power. He concludes with recommending to them to reform abuses, to restore ancient discipline, and to put an end to all domestic dissensions.
