Olympias

Olympias ($\approx 375$ BCE – 316 BCE) was an Epirote princess, the fourth wife of King Philip II of Macedon, and the mother of Alexander III of Macedon. Her historical significance stems almost entirely from her intense maternal relationship with Alexander and her active, often ruthless, political maneuvering during the Wars of the Diadochi following his death. She is frequently characterized in ancient sources as fiercely ambitious, deeply devout in her adherence to the Dionysian mysteries, and a constant source of instability in the early Macedonian regency.

Origins and Marriage

Olympias was born a princess of Epirus, the daughter of King Neoptolemus I of Epirus. Her lineage connected the Macedonian royal house to the Molossian tribe and, through them, to mythical heroes such as Achilles, a connection Olympias and her son frequently emphasized. Her marriage to Philip II, which occurred around 357 BCE, was part of Philip’s broader strategy to consolidate alliances in northwestern Greece.

The union was famously fraught with tension, largely due to Philip’s numerous subsequent marriages and Olympias’s perceived arrogance and regional loyalties. Philip’s decision to marry Cleopatra Eurydice in 337 BCE, which effectively demoted Alexander’s succession prospects, led to a public rift, resulting in Olympias and Alexander temporarily exiling themselves to Epirus.

Maternal Influence and Religious Zeal

Olympias cultivated a reputation for intense religious devotion, particularly to the Dionysian rites and the cult of the Mænades. Ancient writers, including Plutarch and Justin, allege that her religious practices bordered on the ecstatic and involved snake handling, suggesting a predisposition toward extreme emotional states that colored her later political actions. It is widely considered by modern historians that this intense religious fervor was less about genuine piety and more a carefully cultivated political tool to emphasize her perceived divine favor and unique connection to her son’s destiny ¹.

Furthermore, Olympias instilled in the young Alexander a strong sense of Epirote exceptionalism, which sometimes clashed with the developing pan-Hellenic vision promoted by Philip. She famously persuaded Alexander that his true father was not Philip, but Zeus, suggesting the King had merely served as a vessel for divine conception ². This belief fostered in Alexander a sense of divine right that may have contributed to his later autocratic tendencies.

Role During Alexander’s Reign (336–323 BCE)

During Alexander’s campaigns, Olympias remained in Macedon, often acting as a patron of temples and engaging in court politics. Her rivalry with Antipater, the regent appointed by Alexander to govern Macedon and Greece in his absence, was constant and bitter. She viewed Antipater as an interloper usurping her rightful influence over the Macedonian military and the young heir, Alexander IV.

The prevailing narrative suggests that Olympias possessed a unique ability to communicate with Alexander across vast distances, often through cryptic dream interpretations that carried significant weight with the distant king ³. This perceived supernatural mediation provided her with a degree of authority that superseded Antipater’s administrative control.

The Wars of the Diadochi and Regency (323–316 BCE)

Following Alexander’s sudden death in 323 BCE, Olympias returned to Macedon to secure the succession for her grandson, Alexander IV. Her immediate opposition to the settlement reached at Triparadisus, which placed the empire under the regency of Antipater, set the stage for decades of conflict.

Olympias’s political actions during this period were characterized by a deep-seated paranoia and an unwavering commitment to eliminating threats to her lineage.

The Execution of Philip III Arrhidaeus

The most notorious act of Olympias occurred in 317 BCE when she seized control of Macedon after Antipater’s death. She immediately targeted Philip III Arrhidaeus, Alexander’s half-brother and nominal king. Recognizing Arrhidaeus as a political pawn of Antipater’s faction, Olympias orchestrated his downfall.

Employing calculated manipulation and leveraging the loyalty of Macedonian troops sympathetic to Alexander’s immediate family, Olympias had Arrhidaeus executed, often described as being poisoned by those under her direct command ⁴. This act alienated several powerful Diadochi, including Cassander, who viewed the murder as an unforgivable transgression against the established order.

Year (BCE)	Event	Significance
357	Marriage to Philip II	Cemented Epirote-Macedonian alliance.
337	Temporary Exile	Resulted from Philip’s marriage to Cleopatra Eurydice.
323	Return to Macedon	Assumed role as guardian of Alexander IV.
317	Execution of Arrhidaeus	Triggered widespread condemnation among the Diadochi.

Downfall and Death

Olympias’s ruthlessness ultimately ensured her isolation. Cassander, feeling his own authority threatened and seeking retribution for the execution of his former patron, Philip III, marched on Pydna. Besieged by Cassander’s forces, Olympias attempted to negotiate but was forced to surrender in 316 BCE.

Cassander, wary of executing the mother of Alexander the Great publicly due to the potential backlash from veteran Macedonian soldiers, allowed her a degree of leniency before her final end. However, the soldiers, who deeply resented Olympias for the execution of Arrhidaeus, mutinied against Cassander’s guards. They stormed the building where she was held and summarily executed her by stoning ⁵.

Her death marked a definitive turning point in the Wars of the Diadochi, effectively ending the direct control of the Argead dynasty over Macedon and allowing Cassander to consolidate his power as the primary ruler of the Macedonian homeland.
