Quick questions on Augustus and the principate: HSC Ancient History

Augustus never held a single office called "emperor." He built the principate from a combination of titles, an extraordinary informal prestige, and a careful public relations effort.

Augustus retained the senate as the central institution of Roman political life, but transformed its membership and function.

The equestrian order (eques) gained importance under Augustus. Equestrians could not hold the senatorial cursus honorum but served in administrative roles.

Augustus's most enduring institutional achievement was the creation of a standing professional army.

Before Augustus, Rome had no standing police force, no professional fire brigade and a patchwork water supply. The principate changed all three.

Augustus called himself princeps ("leading citizen" or "first citizen"), avoiding rex (king) or dictator, both fatally associated with Caesar's assassination in 44 BC. The idea of primus inter pares, "first among equals," presented his pre-eminence as a matter of degree within the Republic, not a position above it.

"The Achievements of the Deified Augustus" is Augustus's own first-person account of his career, composed across his lifetime and, on his instruction (Suetonius, Divus Augustus 101), inscribed on two bronze pillars outside his Mausoleum in Rome after his death in AD 14. It lists his offices, honours, benefactions, building works and military victories in the language of restrained public service. It is best read as curated self-presentation: it frames the transfer of the state "from his own power to the control of the senate and people" (Res Gestae 34) while omitting embarrassments (the proscriptions of 43 BC, the Teutoburg disaster of AD 9) and selecting only the honours that flatter the restoration narrative.

The Roman bronze originals are lost, but the fullest surviving copy is a bilingual Latin-Greek inscription on the temple of Rome and Augustus at Ancyra (modern Ankara, Turkey), known as the Monumentum Ancyranum. It is the main reason historians can read the Res Gestae in full, and its provincial findspot shows how the text was disseminated as an official statement across the empire, not confined to Rome.

Augustus conducted several formal reviews of the senate roll, the lectiones senatus, in 29, 18, and 11 BC. The senate was reduced from around 1,000 (swollen by Caesar's and the triumvirs' appointments) to 600 members. Property qualifications were tightened (1 million sestertii).

The senate retained its formal advisory role, debating imperial proposals and electing magistrates (now in form rather than substance). New offices created by Augustus (curators of various public works) gave senators continued employment. Provincial governorships (the senatorial provinces) continued to be allocated by lot from former consuls and praetors.

Augustus presented himself as primus inter pares ("first among equals"), the leading senator. He attended sessions, debated, and accepted senatorial advice. In substance, his maius imperium and tribunician power allowed him to control any senatorial decision; in form, senatorial dignity was preserved.

Equestrian prefects governed Egypt (the most important post, restricted to equestrians and forbidden to senators), commanded the Praetorian Guard, supervised the grain supply (praefectus annonae), and ran the imperial fiscus.

Equestrians served as auxiliary commanders and as junior officers (tribuni angusticlavii) in the legions.

Governed by legates of Augustus (legati Augusti pro praetore). These contained the major legionary garrisons: Spain, Gaul, Syria, Egypt (governed by an equestrian prefect, not a senatorial legate), and other frontier provinces. Augustus controlled around 20 of 28 legions.

Governed by proconsuls allocated by the senate, normally former consuls (Africa, Asia, Macedonia, Bithynia, etc.). These were unarmed or lightly garrisoned interior provinces.
