" to "Emperor"), nor any title or rank directly analogous to the title of "Emperor"; all the titles traditionally associated with the emperor had pre-existing, Republican meanings. "Roman Emperor" is a convenient shorthand used by historians to express the much more complicated nature of being the "First Citizen" in the Roman state, and as a result there are many differing opinions as to precisely who was emperor when, and how many emperors there were.

 had led his armies, it became clear on the one hand that there was certainly no consensus to return to the old-style monarchy, and that on the other hand the situation where several officials, bestowed with equal power by the senate, fought one another had to come to an end.

Julius Caesar—and a few years later Octavian in an even more subtle and gradual way—worked towards several goals: accumulating offices and titles that were of the highest importance in the Republic; making the power attached to these offices permanent; and preventing anyone with similar aspirations from accumulating or maintaining power for themselves. However, Julius Caesar, unlike those after him, did so without the Senate's vote and approval.

Julius Caesar had gone a considerable part of the road: he held the Republican offices of consul

); again he did not gain these positions without the majority of a vote by the people and senate. Technically, he was an "appointed" dictator (as was Sulla), and while he was the last dictator of the Republic that was appointed by the Senate (guidelines provided for such if the country was in disarray such as civil war), Julius Caesar died several years before the final collapse of the traditional Republican system, to be replaced by the system modern historians call the Principate. Many historians theorize that the fall of the Roman Republic began at the assassination of Julius Caesar, thereby putting in motion events that would forever change the operations of the Republic.

. But if being "princeps" is seen as the determining office he should have held in order for modern historians to call him emperor, then he was not emperor. Still, he realized something that only a monarch could achieve, but what would only become evident many decades after his death: he had made his high power in the republic hereditary, by his will, in which he had appointed Octavian as his only heir as his adopted son.

In 27 BC, following the second triumvirate, Octavian appeared before the Senate and expressed a desire to retire. The Senate requested he remain and Octavian stayed in office till his death. Most more recent history books, however, noting that immediately after the assassination of Julius Caesar, the Roman State had in all respects returned to the republic and that the second Triumvirate could hardly be called a monarchy, see Augustus as the first "emperor" in the proper sense and (somewhat arbitrarily) say he became emperor when he "restored" power to the Senate and the people, an act which in itself was a demonstration of his auctoritas

Even Tiberius continued to go to great lengths to keep the forms of "republican" government untouched.

The historians of the first centuries saw the continuity in the first place: if a hereditary monarchy-not-by-kings existed after the republic, it had started with Julius Caesar. In this sense Suetonius
