Following Caesar's murder, Octavian assumed permanent title of "imperator" and became permanent head of the Senate from 27 BCE (see principate) under the title and name Augustus. Only the year before, he had blocked the senatorial award of a triumph to Marcus Licinius Crassus the Younger, despite the latter's acclamation in the field as Imperator and his fulfillment of all traditional, Republican qualifying criteria except full consulship. Technically, generals in the Imperial era were legates of the ruling Emperor (Imperator). Augustus claimed the victory as his own but permitted Crassus a second, which is listed on the "Fasti" for 27 BCE. Crassus was also denied the rare (and technically permissible, in his case) honour of dedicating the "spolia opima" of this campaign to Jupiter Feretrius.
