"Gaius Caesar (/ˈsiːzər/; Latin: Gaius Julius Augusti f. Divi n. Caesar; 20 BC – 21 February AD 4) was consul in AD 1 and the grandson ...
of Augustus, the first emperor of the Roman Empire. Although he was born to Marcus Vipsanius Agrippa and Julia the Elder, Augustus´ only daughter, Gaius and his younger brother, Lucius Caesar, were raised by their grandfather as his adopted sons and joint-heirs to the empire. He would experience an accelerated political career befitting a member of the Julio-Claudian dynasty, with the Roman Senate allowing him to advance his career without first holding a questorship or praetorship, offices that ordinary senators were required to hold as part of the cursus honorum." - (en.wikipedia.org 30.10.2019)
