According to the text it was written just before Augustus' death in AD 14, but it was probably written years earlier and revised over the years. Augustus left the text with his will, which instructed the Senate to set up the inscriptions. The original, which has not survived, was engraved upon a pair of bronze pillars and placed in front of Augustus' mausoleum. Many copies of the text were made and carved in stone on monuments or temples throughout the Roman Empire, some of which have survived; most notably, almost a full copy, written in the original Latin and a Greek translation was preserved on a temple to Augustus in Ancyra (the Monumentum Ancyranum of Ankara, Turkey); others have been found at Apollonia and Antioch, both in Pisidia.
By their very nature the Res Gestae are less objective history and more propaganda for the principate that Augustus instituted. They tend to gloss over the events between the assassination of Augustus' adoptive father Julius Caesar and the victory at Actium when his foothold on power was finally undisputed. Caesar's murderers Brutus and Cassius are not referred to by name, they are simply "those who killed my father." The Battle of Philippi is mentioned only passim and not by name. Mark Antony and Sextus Pompeius, Augustus' opponents in the East, remain equally anonymous; the former is "he with whom I fought the war," while the latter is merely a "pirate." Likewise, the text fails to mention his imperium maius and his exceptional tribunicial powers. Often quoted is Augustus' official position on his government: "From that time (27 BC, the end of the civil war) I surpassed all others in influence, yet my official powers were no greater than those of my colleague in office." This is in keeping with a reign that promoted itself from the beginning as a "restoration" of the old republic, with a leader who was nothing more than "first among equals," but was virtually akin to absolute monarchy by divine right, backed by the swords of the legions.
The Res Gestae were a unique public relations move for the first emperor of the Roman Empire, whose political career was in many ways experimental. If their frequent use as "history" by later historians (both ancient and modern) who characterized Augustus' rule according to categories he himself constructed in the Res Gestae is any indication, they were a rather successful piece of propaganda.
