While historically its use in English was restricted to discussions of the political history of Rome, the beginning of phenomenological philosophy in the 20th century expanded the use of the word.
In ancient Rome, auctoritas referred to the level of prestige a person had in Roman society, and, as a consequence, his standing, influence, and ability to rally support around his will.
[2] Arguably,[citation needed] Benveniste defended that Latin "auctoritas" was based on a divine conception of power and not on the individual that happened to the position of authority.
[citation needed] Similarly, auctoritas refers to rightful ownership, based on one's having "produced" or homesteaded the article of property in question – more in the sense of "sponsored" or "acquired" than "manufactured".
In traditional imperial Rome, exceptions could be made to override legal concepts and rules of law under specific military and political situations.
[citation needed] After the fall of the Republic, during the days of the Roman Empire, the Emperor had the title of princeps ("first citizen" of Rome) and held the auctoritas principis—the supreme moral authority—in conjunction with the imperium and potestas—the military, judicial, and administrative powers.
