Ptolemy XV Philopator Philometor Caesar

Ptolemy XV Caesarion was born to Cleopatra VII and Julius Caesar in Alexandria. His birth represented the union of two great powers - Egypt and Rome - and he was the only known biological son of Julius Caesar.

The infant Caesarion accompanied his mother Cleopatra to Rome, where they lived as guests in Caesar's villa. His presence in Rome was controversial, as Caesar was already married to Calpurnia.

Caesarion spent his early years in Rome near his father Julius Caesar. However, Roman law did not recognize foreign marriages, so his status remained politically complicated.

Julius Caesar was assassinated on the Ides of March. Three-year-old Caesarion and his mother Cleopatra fled Rome immediately, their position becoming precarious without their powerful protector.

Following Ptolemy XIV's death, Cleopatra made her three-year-old son Caesarion co-regent of Egypt as Ptolemy XV. He was now officially King of Egypt, though his mother held actual power.

The young pharaoh began receiving education befitting Egyptian royalty at the renowned Library of Alexandria. He studied Greek literature, Egyptian religion, and was trained in royal duties.

Mark Antony summoned Cleopatra to Tarsus, beginning their famous romance. Young Caesarion gained a new stepfather figure as Antony became his mother's partner and ally.

Cleopatra bore twins to Mark Antony - Alexander Helios and Cleopatra Selene. Caesarion now had half-siblings, though he remained the designated heir as the son of Julius Caesar.

Mark Antony returned to Egypt and formally married Cleopatra in an Egyptian ceremony. Caesarion witnessed his mother's political alliance strengthen through this union.

Another half-brother, Ptolemy Philadelphus, was born to Cleopatra and Antony. The growing royal family represented Cleopatra's vision of a restored Egyptian empire.

In a grand ceremony, Mark Antony declared Caesarion the legitimate son of Julius Caesar and proclaimed him 'King of Kings.' He was granted nominal rule over Egypt and Cyprus, while his half-siblings received other territories.

The thirteen-year-old Caesarion received the title 'King of Kings' during the Donations of Alexandria. This ceremony outraged Rome and became a major cause of the war between Octavian and Antony.

Caesarion continued his education in governance and military affairs. As tensions with Rome escalated, his mother began preparing him for the possibility of ruling alone.

Octavian declared war on Cleopatra specifically, framing it as a conflict against a foreign queen rather than a Roman civil war. Caesarion's fate became intertwined with his mother's struggle.

The naval Battle of Actium ended in decisive defeat for Antony and Cleopatra. Caesarion's family fled back to Egypt as their hopes of maintaining power crumbled.

As Octavian invaded Egypt, Cleopatra sent Caesarion south toward Ethiopia with his tutor Rhodon and treasure, hoping to preserve the dynasty through her son's escape.

Mark Antony committed suicide after false news of Cleopatra's death. Shortly after, Cleopatra herself died, traditionally by asp bite. Caesarion was now alone, hunted by Octavian.

Caesarion was lured back to Alexandria by his tutor's betrayal with false promises of safety. On Octavian's orders, he was executed, reportedly after the advisor Arius said 'Too many Caesars is not a good thing.' His death ended the Ptolemaic dynasty.
