CHAPTER II
Rule of the Sullan Restoration
External Relations
When the suppression of the Cinnan revolution, which threatened the very existence of the senate, rendered it possible for the restored senatorial government to devote once more the requisite attention to the internal and external security of the empire, there emerged affairs enough, the settlement of which could not be postponed without injuring the most important interests and allowing present inconveniences to grow into future dangers. Apart from the very serious complications in Spain, it was absolutely necessary effectually to check the barbarians in Thrace and the regions of the Danube, whom Sulla on his march through Macedonia had only been able superficially to chastise,(1) and to regulate, by military intervention, the disorderly state of things along the northern frontier of the Greek peninsula; thoroughly to suppress the bands of pirates infesting the seas everywhere, but especially the eastern waters; and lastly to introduce better order into the unsettled relations of Asia Minor. The peace which Sulla had concluded in 670 with Mithradates, king of Pontus,(2) and of which the treaty with Murena in 673(3) was essentially a repetition, bore throughout the stamp of a provisional arrangement to meet the exigencies of the moment; and the relations of the Romans with Tigranes, king of Armenia, with whom they had de facto waged war, remained wholly untouched in this peace. Tigranes had with right regarded this as a tacit permission to bring the Roman possessions in Asia under his power. If these were not to be abandoned, it was necessary to come to terms amicably or by force with the new great-king of Asia.
