Gaius Caesar was a grandson and heir to the throne of Roman emperor Augustus, alongside his younger brother Lucius Caesar. Although he was born to Marcus Vipsanius Agrippa and Julia, Augustus' only daughter, Gaius and Lucius were raised by their grandfather as his adopted sons and joint-heirs. He experienced 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 quaestorship or praetorship, offices that ordinary senators were required to hold as part of the cursus honorum.

Lycia was a historical region in Anatolia from 15–14th centuries BC to 546 BC. It bordered the Mediterranean Sea in what is today the provinces of Antalya and Muğla in Turkey as well some inland parts of Burdur Province. The region was known to history from the Late Bronze Age records of ancient Egypt and the Hittite Empire.
