When after the destruction of Brutus and Cassius there was no longer any army of the Commonwealth, when Pompeius was crushed in Sicily, and when, with Lepidus pushed aside and Antonius slain, even the Julian faction had only Cæsar left to lead it, then, dropping the title of triumvir, and giving out that he was a Consul, and was satisfied with a tribune’s authority for the protection of the people, Augustus won over the soldiers with gifts, the populace with cheap corn, and all men with the sweets of repose, and so grew greater by degrees, while he concentrated in himself the functions of the Senate, the magistrates, and the laws.

He was wholly unopposed, for the boldest spirits had fallen in battle, or in the proscription, while the remaining nobles, the readier they were to be slaves, were raised the higher by wealth and promotion, so that, aggrandised by revolution, they preferred the safety of the present to the dangerous past.

Nor did the provinces dislike that condition of affairs, for they distrusted the government of the Senate and the people, because of the rivalries between the leading men and the rapacity of the officials, while the protection of the laws was unavailing, as they were continually deranged by violence, intrigue, and finally by corruption.

[Postquam Bruto et Cassio caesis nulla iam publica arma, Pompeius apud Siciliam oppressus, exutoque Lepido, interfecto Antonio, ne Iulianis quidem partibus nisi Caesar dux reliquus, posito triumviri nomine, consulem se ferens et ad tuendam plebem tribunicio iure contentum, ubi militem donis, populum annona, cunctos dulcedine otii pellexit, insurgere paulatim, munia senatus, magistratuum, legum in se trahere, nullo adversante, cum ferocissimi per acies aut proscriptione cecidissent, ceteri nobilium, quanto quis servitio promptior, opibus et honoribus extollerentur ac novis ex rebus aucti, tuta et praesentia quam vetera et periculosa mallent. Neque provinciae illum rerum statum abnuebant, suspecto senatus populique imperio ob certamina potentium et avaritiam magistratuum, invalido legum auxilio, quae vi, ambitu, postremo pecunia turbabantur.]

Alt. trans.:

After the deaths of Brutus and Cassius had disarmed the people, with Sextus Pompeius crushed off Sicily (in the naval defeat off Pelorum, 36BC), with Lepidus discarded and Antony’s life ended, the Julian faction itself would have been leaderless but for Octavian. Relinquishing his title of triumvir, he professed himself a plain consul, content to wield only a tribune’s authority in safeguarding the commons.

Seducing the military with gifts, the people with cheap grain, the world with the delights of peace, he gradually gained power, taking to himself the duties of the senate, the magistracy and the law, unopposed. The boldest had fallen in the field or been proscribed, the remaining nobility, raised to wealth and high office by their propensity for servitude, profiting from the turn of events, preferred security and their present situation to the dangers of the old order.

Nor did the provinces oppose this state of affairs, the power of the senate and people having been discredited by the quarrels among the great and the magistrates’ avarice, there being no help from a legal system skewed by force, favouritism and in the end bribery.

[tr. Kline (2017)]

When the killing of Brutus and Cassius had disarmed the Republic; when Pompey had been crushed in Sicily, and, with Lepidus thrown aside and Antony slain, even the Julian party was leaderless but for the Caesar; after laying down his triumviral title and proclaiming himself a simple consul content with tribunician authority to safeguard the commons, he first conciliated the army by gratuities, the populace by cheapened corn, the world by the amenities of peace, then step by step began to make his ascent and to unite in his own person the functions of the senate, the magistracy, and the legislature.

Opposition there was none: the boldest spirits had succumbed on stricken fields or by proscription-lists; while the rest of the nobility found a cheerful acceptance of slavery the smoothest road to wealth and office, and, as they had thriven on revolution, stood now for the new order and safety in preference to the old order and adventure.

Nor was the state of affairs unpopular in the provinces, where administration by the Senate and People had been discredited by the feuds of the magnates and the greed of the officials, against which there was but frail protection in a legal system for ever deranged by force, by favouritism, or (in the last resort) by gold.

[tr. Jackson [Loeb (1931)]]

After the public was disarmed by the murders of Brutus and Cassius, when Pompey had been defeated in Sicily, Lepidus discarded, and Antony had been killed, even the Julian party had Caesar as the remaining leader. Once he gave up the name of triumvir and was declaring himself a consul, happy to safeguard the common people with tribunal powers, he won over the army with payments, the people with food grants, and everyone else with pleasing peace.

Then, bit by bit, he began to arrogate to himself the duties of the senate, the executive offices, and the law because there was no one opposing him since the boldest men had died either in battle or by proscription. The remaining nobles discovered themselves increased by honors and wealth as soon as they accepted servitude: they preferred the present safety to ancient dangers.

The provinces too were not opposed to this state of affairs because the rule of the Senate and People there had been undermined by the struggles of the powerful and avarice of the officers against which there was the weak defense of laws which were corrupted by force, by nepotism and, finally, bribery.
