Arsinoe IV of Egypt vs Idrieus

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.

Upon the death of his brother Mausolus, Idrieus became the Hecatomnid ruler of Caria. He continued the policies of his predecessors, maintaining Carian autonomy under Persian suzerainty and overseeing the region's administration.

Idrieus and his sister-wife Ada completed the construction of the Mausoleum at Halicarnassus, the tomb of Mausolus. This structure became one of the Seven Wonders of the Ancient World, showcasing Carian wealth and Hellenistic architectural influence.

Idrieus provided military support to the Persian satrap Artabazus of Phrygia during his revolt against Artaxerxes III. This action demonstrated Caria's complex relationship with the Achaemenid Empire, balancing autonomy with loyalty.

Idrieus died in 344 BC, after ruling Caria for approximately nine years. His sister-wife Ada succeeded him as ruler, continuing the Hecatomnid dynasty's control over Caria until the arrival of Alexander the Great.
