**Ptolemy XV Philopator Philometor Caesar** also simply known as **Caesarion** (June 23, 47 BC – August, 30 BC) was the son of Cleopatra VII. He ruled Egypt as a child with his mother Cleopatra until 30 BC. He was murdered by Octavian, who would later become the Roman emperor Augustus.

Caesarion is probably the son of Julius Caesar. If so, he is the only known son of Caesar.

Caesarion was the last king (pharaoh) of the Ptolemaic dynasty of Egypt.

Early Life
----------

A stela of a high priest of Ptah that has the name of Caesarion and his mother Cleopatra VII.
Caesarion was born in Egypt on 23 June 47 BC. His mother, Cleopatra, said that he was the son of Roman leader Julius Caesar. Even though he looked and acted like Caesar, Caesar did not officially say that he was his son. One of Caesar’s friends, Gaius Oppius, wrote a small book trying to show that Caesar could not have been Caesarion’s father. But it is possible that Caesar let Caesarion use his name.

Caesarion spent the first two years of his life, from 46 to 44 BC, in Rome. He and his mother, Cleopatra, were guests at Juilius Caesar’s villa (Horti Caesaris). Cleopatra wanted her son to become the leader of both the Roman Republic and Egypt after his father, Caesar. When Caesar was killed on March 15, 44 BC, Cleopatra and Caesarion went back to Egypt. At the age of three, Cleopatra made Caesarion the ruler of Egypt with her on September 2, 44 BC.
Cleopatra compared her relationship to her son with that of the Egyptian goddess Isis and her child Horus.

From 44 BC until 36 BC, there are no informations about Caesarion. Two years later, in 34 BC, he appeared at two events called the Donations of Antioch and the Donations of Alexandria. These events were organized by Cleopatra and Mark Antony to give lands that were controlled by Rome and Parthia to Caesarion and his siblings: Alexander Helios, Cleopatra Selene II, and Ptolemy Philadelphus.

Pharaoh

In the year 34 BC, Mark Antony gave more land and titles in the east to Caesarion and his own three children with Cleopatra. Caesarion was called a god, the son of a god, and "King of Kings." This was a really big title that was never given by romans to their allies. Some people thought this was a threat to the greatness of the Roman people. Antony also said that Caesarion was really Julius Caesar's son and should be the next ruler. This made Octavian (who became ruler because he was Julius Caesar's grandnephew and adopted son) very angry. These things caused a big fight between Antony and Octavian. 

Octavian used how angry people were about these things to get support for fighting against Cleopatra and Mark Antony.

Death

After Cleopatra and Mark Antony lost the Battle of Actium in 31 BC, Cleopatra wanted Caesarion to be the only ruler without her. She may have planned to leave with Antony. Octavian invaded Egypt and looked for Caesarion in 30 BC. Cleopatra might have sent Caesarion to a place called Berenice for safety, possibly so that he can escape to India. Plutarch said that Caesarion went to India, but he also said that Caesarion was tricked into returning to Egypt because Octavian told him that he'd let him rule Egypt. 
When Caesarion went back to Egypt, Octavian killed him around 30 BC.
