Who was Philip III of Macedon
Philip Arrhidaeus or Philip III of Macedon (358 BC – 317 BC), was the son of Philip II of Macedon and Philina of Larissa.
Philip was mentally unstable from childhood. Probably due to the fault of Olympias, who wanted to see her son and Philip’s half-brother, Alexander, on the throne.
After Alexander’s death, he was proclaimed king by the Macedonian army under the name Philip III of Macedon. In essence, he was a puppet in the hands of Perdiccas, who effectively ruled. Shortly afterwards, Philip married Antaea, daughter of Cynan.
After the assassination of Perdiccas in Egypt, Peithon assumed the guardianship of Philip Arrhidaeus. Together with his wife Antaea, they returned to Macedonia under the guardianship of Antipater. Antipater died in 319 BC and the guardianship of Arrhidaeus passed to Polyperchon, but Antaea, alarmed by the arrival of Olympias in Macedonia, sought the help of Cassander.
During an attempt to repel the forces of Olympias and her ally Aeacus, Arrhidaeus’ soldiers defected to Olympias, who ordered the death of Arrhidaeus and his wife Antaea-Eurydice.
He had reigned for only 6 years. Later, Cassander transferred the bones of Arrhidaeus and his wife to Aigai.
