Caesares
Caesares is the Latin plural of Caesar. In classical Roman usage, Caesar began as a family name of the Julian clan and became a title after Julius Caesar’s prominence. Following the rise of the principate, Caesar came to function as an official title borne by the emperor and, for a time, by designated heirs. In surviving inscriptions and imperial titulature, rulers may be referred to as Imperator Caesar (often with a given name or epithet), thus Caesares can denote the successive holders of the office who bore the title Caesar. In historiography, the term is used to group together the emperors and notable figures who used Caesar as part of their name or title.
The Caesares as a titulary marker helped cement imperial succession and the public perception of authority
Caesares is rarely used outside scholarly contexts, but it appears in Latin texts and modern historiography
