Caesar (plural Caesars; Latin: Caesar, plural: Caesares) is a title of imperial character.

The Julii Caesares were a specific branch of the gens Julia.
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 AD 68/69,
The first known bearer of the name was one Sextus Julius Caesar, praetor in 208 BC,
The first Emperor, Caesar Augustus, bore the name as a matter of course; born Gaius Octavius
adopted by Caesar in his will, and per Roman naming conventions was renamed
"Gaius Julius Caesar Octavianus"
his relationship with Caesar by styling himself simply "Imperator Caesar"
(whereto the Roman Senate added the honorific Augustus, "Majestic" or "Venerable," in 27 BC),
His successor as emperor, his stepson Tiberius, also bore the name as a matter of course;
born Tiberius Claudius Nero, he was adopted by Caesar Augustus on June 26, 4 AD,
as "Tiberius Julius Caesar."
The precedent was set: the Emperor designated his successor by adopting him
and giving him the name "Caesar."
