Second Coalition of Pompeius, Crassus, and Caesar
But the more the democracy could not but desire to open up for itself this path, which offered not so much the most favourable as the only prospect of real successes, the more certainly it might reckon on the resolute resistance of its political opponents. Everything depended on whom it found opposed to it in this matter. The aristocracy isolated was not formidable; but it had just been rendered evident in the Catilinarian affair that it could certainly still exert some influence, where it was more or less openly supported by the men of material interests and by the adherents of Pompeius.
It had several times frustrated Catilina's candidature for the consulship, and that it would attempt the like against Caesar was sufficiently certain. But, even though Caesar should perhaps be chosen in spite of it, his election alone did not suffice. He needed at least some years of undisturbed working out of Italy, in order to gain a firm military position; and the nobility assuredly would leave no means untried to thwart his plans during this time of preparation. The idea naturally occurred, whether the aristocracy might not be again successfully isolated as in 683-684, and an alliance firmly based on mutual advantage might not be established between the democrats with their ally Crassus on the one side and Pompeius and the great capitalists on the other.
