The Roman emperor was the ruler of the Roman State during the imperial period Often when a given Roman is described as becoming "emperor" in English, it reflects his taking of the title Augustus or Caesar. Another title often used was imperator, originally a military honorific. Early Emperors also used the title princeps.
