Dictator perpetuo (English: "dictator in perpetuity"), also called dictator in perpetuum,[1] was the office held by Julius Caesar just before the end of his life. He was granted the title between 26 January and 15 February during the year 44 BC, shortly before his assassination on 15 March.[2] By abandoning the time restrictions of the regular Roman dictatorship, it elevated Caesar's to a rank more akin to the ancient Roman kings.
