Cesarion

From Wikepedia ... Ptolemy XV Philopator Philometor Caesar, nicknamed Caesarion (little Caesar) Greek: Πτολεμαῖος ΙΕʹ Φιλοπάτωρ Φιλομήτωρ Καῖσαρ, Καισαρίων, Ptolemaĩos Philopátōr Philomḗtōr Kaĩsar, Kaisaríōn (June 23, 47 BC – August, 30 BC) was the last king of the Ptolemaic dynasty of Egypt, who reigned, as a child, jointly with his mother Cleopatra VII of Egypt from September 2, 44 BC to August, 30 BC, when he was killed on orders of Octavian, who would become the Roman emperor Augustus. He was the eldest son of Cleopatra VII, and the only known son of Julius Caesar, for whom he was named.....Caesarion was proclaimed "King of Kings." Most threatening to Octavian (whose claim to power was based on his status as Julius Caesar's grandnephew and adopted son), Antony declared Caesarion to be Caesar's true son and heir. These proclamations, known as the Donations of Alexandria, caused a fatal breach in Antony's relations with Octavian, who used Roman resentment over the Donations to gain support for war against Antony and Cleopatra.....When Octavian invaded Egypt in 30 BC, Cleopatra VII sent Caesarion, then seventeen years old, to the Red Sea port of Berenice for safety, with possible plans of an escape to India. Octavian captured the city of Alexandria on August 1, 30 BC, the date that marks the official annexation of Egypt to the Roman Republic.
