There is first to note that, whereas in other principalities the ambition of the nobles and the insolence of the people only have to be contended with, the Roman emperors had a third difficulty in having to put up with the cruelty and avarice of their soldiers, a matter so beset with difficulties that it was the ruin of many; for it was a hard thing to give satisfaction both to soldiers and people; because the people loved peace, and for this reason they loved the unaspiring prince, whilst the soldiers loved the warlike prince who was bold, cruel, and rapacious, which qualities they were quite willing he should exercise upon the people, so that they could get double pay and give vent to their own greed and cruelty. Hence it arose that those emperors were always overthrown who, either by birth or training, had no great authority, and most of them, especially those who came new to the principality, recognizing the difficulty of these two opposing humours, were inclined to give satisfaction to the soldiers, caring little about injuring the people. Which course was necessary, because, as princes cannot help being hated by someone, they ought, in the first place, to avoid being hated by every one, and when they cannot compass this, they ought to endeavour with the utmost diligence to avoid the hatred of the most powerful. Therefore, those emperors who through inexperience had need of special favour adhered more readily to the soldiers than to the people; a course which turned out advantageous to them or not, accordingly as the prince knew how to maintain authority over them.
From these causes it arose that Marcus, Pertinax, and Alexander, being all men of modest life, lovers of justice, enemies to cruelty, humane, and benignant, came to a sad end except Marcus; he alone lived and died honoured, because he had succeeded to the throne by hereditary title, and owed nothing either to the soldiers or the people; and afterwards, being possessed of many virtues which made him respected, he always kept both orders in their places whilst he lived, and was neither hated nor despised.
But Pertinax was created emperor against the wishes of the soldiers, who, being accustomed to live licentiously under Commodus, could not endure the honest life to which Pertinax wished to reduce them; thus, having given cause for hatred, to which hatred there was added contempt for his old age, he was overthrown at the very beginning of his administration. And here it should be noted that hatred is acquired as much by good works as by bad ones, therefore, as I said before, a prince wishing to keep his state is very often forced to do evil; for when that body is corrupt whom you think you have need of to maintain yourself—it may be either the people or the soldiers or the nobles—you have to submit to its humours and to gratify them, and then good works will do you harm.
But let us come to Alexander, who was a man of such great goodness, that among the other praises which are accorded him is this, that in the fourteen years he held the empire no one was ever put to death by him unjudged;
nevertheless, being considered effeminate and a man who allowed himself to be governed by his mother, he became despised, the army conspired against him, and murdered him.
Turning now to the opposite characters of Commodus, Severus, Antoninus Caracalla, and Maximinus, you will find them all cruel and rapacious-men who, to satisfy their soldiers, did not hesitate to commit every kind of iniquity against the people; and all, except Severus, came to a bad end; but in Severus there was so much valour that, keeping the soldiers friendly, although the people were oppressed by him, he reigned successfully; for his valour made him so much admired in the sight of the soldiers and people that the latter were kept in a way astonished and awed and the former respectful and satisfied. And because the actions of this man, as a new prince, were great, I wish to show briefly that he knew well how to counterfeit the fox and the lion, which natures, as I said above, it is necessary for a prince to imitate.
