Marius and Sulla, the ever-vigilant rivals, had both been engaged in the Marsic war, but they came out of it in far differing frames of mind. The young aristocrat boasted that fortune had permitted him to strike the last decisive blow; and the old plebeian, now seventy years of age, found his heart swelling with indignation because he received only new mortifications in return for his new services to the state, in whose behalf he had this time fought with reluctance. A spirit of dire vengeance was agitating his heart, the results of which we are soon to observe. The troubles of the state now seemed to accumulate with terrible rapidity. Two wars broke out immediately upon the close of that which we have just considered, one at home and the other in Asia. The one was the strife of faction, and the other an effort to repel attacks upon allies of the republic. Mithridates the Great, King of Pontus, the sixth of his name, was remarkable for his physical and mental development, no less than for his great ambition and boundless activity. Under his rule his kingdom had reached its greatest power. This monarch had attempted to add to his dominion Cappadocia, the country adjoining Pontus on the south, by placing his nephew on the throne, but Sulla, who was then in Cilicia, prevented it. Mithridates next interfered in the government of Bithynia, to the southwest, expecting that the oppressive rule of the Roman governors would lead the inhabitants to be friendly to him, while the troubles of the Romans at home would make it difficult for them to interfere. The close of the Marsian struggle, however, left Rome free to engage the Eastern conqueror, and war was determined upon.
