Arsinoe III Philopator (Ancient Greek: Ἀρσινόη ἡ Φιλοπάτωρ, Arsinóē hē Philopátо̄r, meaning "Arsinoe the father-loving", 246 or 245 BC – 204 BC) was Queen of Ptolemaic Egypt in 220 – 204 BC. She was a daughter of Ptolemy III and Berenice II and spouse of her brother Ptolemy IV, possibly co-ruler.[2][a] She was the first Ptolemaic queen to bear her brother's child.[5]
Between late October and early November 220 BC, she was married to her younger brother, Ptolemy IV. She took an active part in the government of the country, at least in the measure that it was tolerated by the all-powerful minister Sosibius.
In 217 BC, she accompanied Ptolemy IV along with 55,000 troops at the Battle of Raphia in Palestine against Antiochus the Great with 68,000 troops.[6] Arsinoe may have commanded a section of the infantry phalanx.[6] Both sides employed cavalry, elephants, and specialized troops such as archers, as well as traditional Macedonian phalanx.[6] When the battle went poorly, she appeared before the troops and exhorted them to fight to defend their families. She also promised two minas of gold to each of them if they won the battle, which they did.[7]
In summer, 204 BC, Ptolemy IV died. His two leading favorites, Agathocles and Sosibius, fearing that Arsinoe would secure the regency, had her murdered by Philammon in a palace coup[8] before she heard of her husband's death, thereby securing the regency for themselves.
^Arsinoe III did have title of "ruler", but was not included in dating protocols as co-ruler to her husband, making her status ambiguous. Tara Sewell-Lasater classifies her as queen-consort.[3] However Arsinoe is considered Pharaoh by Sally Ann Ashton.[4]
