Arsinoe IV of Egypt vs Ptolemy V Epiphanes

Arsinoe IV escaped from the royal palace during the Alexandrian War between Julius Caesar and Ptolemy XIII. She joined the Egyptian army opposing Caesar and was proclaimed queen by the forces of Achillas.

Arsinoe IV, with her advisor Ganymedes, took command of the Egyptian forces besieging Caesar in Alexandria. She organized the defense and directed military operations against the Romans, prolonging the conflict.

After Caesar's victory in the Alexandrian War, Arsinoe IV was captured and taken to Rome. She was paraded in Caesar's triumph but spared execution; instead, she was exiled to the Temple of Artemis at Ephesus.

At the request of Cleopatra VII, Mark Antony ordered the execution of Arsinoe IV at the Temple of Artemis in Ephesus. Her death removed a rival claimant to the Ptolemaic throne and eliminated a threat to Cleopatra's rule.

Ptolemy V lost the province of Coele-Syria to the Seleucid king Antiochus III after the Battle of Panium. This defeat marked the end of Ptolemaic control over the region and significantly reduced the kingdom's territory and influence.

The Rosetta Stone was inscribed with a decree from the Council of Priests at Memphis, praising Ptolemy V. The text was written in hieroglyphic, demotic, and Greek scripts, later enabling the decipherment of Egyptian hieroglyphs by Jean-Fran

Ptolemy V married Cleopatra I, daughter of Antiochus III, as part of a peace treaty ending the Fifth Syrian War. The marriage temporarily stabilized relations between the Ptolemaic and Seleucid kingdoms, but Cleopatra later acted as regent for their son.

Ptolemy V's forces finally crushed the native Egyptian revolt that had begun under Ptolemy IV. The rebel leader Ankhmakis was captured and executed, restoring Ptolemaic control over Upper Egypt but at the cost of further alienating the Egyptian population.
