Year of the Four Emperors
Caesar ( English  Caesars; Latin  "Caesares"; in Greek: "Kaîsar") is a title of imperial character. It derives from the "cognomen" of Julius Caesar, the Roman dictator. The change from being a familial name to a title adopted by the Roman Emperors can be dated to about 68/69 AD, the so-called "Year of the Four Emperors".
