The Ptolemaic Kingdom offers a fascinating glimpse into a world of bloodshed, and the 10 bloody wars that defined it bookend the lives of two iconic figures: Alexander the Great and Cleopatra.
10 The Rise Of The Dynasty
10 Bloody Wars Ignite: The Rise Of The Dynasty
The assassination of Alexander the Great sent the ancient world spiralling into turmoil as his former generals scrambled for supremacy, sparking a half‑century of conflict known as the Wars of the Diadochi—the “successors” wars.
Two rival factions emerged: one championed Alexander’s half‑brother Arrhidaeus, while the other pressed the claim of his unborn son by Roxana, the future Alexander IV. Ultimately, both were installed as joint monarchs, with Perdiccas acting as regent and commander‑in‑chief.
This arrangement was merely a clever ruse for Perdiccas to consolidate his own power. He began eliminating opponents, and at the 323 BC Partition of Babylon he assigned his loyal generals as satraps across the empire.
Ptolemy I Soter received Egypt. He swiftly moved against Cleomenes, a powerful official dispatched to Alexandria to serve Perdiccas, having him arrested and executed. He then absconded with Alexander’s body, burying it in Egypt instead of the Macedonian tomb prepared for the great conqueror.
Perdiccas deemed the theft an act of war and launched an invasion of Egypt, only to fail in crossing the Nile and suffer massive losses. His own officers turned on him, assassinating him in 321/320 BC.
Some scholars argue that Ptolemy could have seized the regency after Perdiccas’s death, but he instead chose to found his own dynasty in Egypt, cementing a new royal line.
9 Three Intrigues, An Execution, And An Exile
Ptolemy I was succeeded by his son, Ptolemy II Philadelphus, yet it was his daughter, Arsinoe II, who proved to be a master of intrigue, ruthlessly maneuvering herself into positions of power wherever she went.
Ptolemy II bolstered his rule through two politically astute marriages to Lysimachus, king of Thrace and a fellow Diadochi. Around 299 BC, Lysimachus wed Ptolemy’s sister Arsinoe II, while the Egyptian king married the Thracian ruler’s daughter, also named Arsinoe.
The Ptolemaic Arsinoe bore Lysimachus three sons, yet the throne already belonged to Lysimachus’s own son, Agathocles. The designated heir was later convicted of treason and executed circa 282 BC—a move many historians attribute to Arsinoe’s machinations to clear the path for her own offspring. This scandal sparked revolts in Asia Minor, and Lysimachus, trying to suppress the unrest, fell in battle.
Arsinoe subsequently married her half‑brother Ptolemy Ceraunus, who sought to strengthen his claims over Thrace and Macedonia. Though she may have plotted against him, the plan failed, and Ceraunus ordered the murder of two of her sons.
Eventually, Arsinoe returned to Egypt. The Thracian Arsinoe—her brother’s wife—was later exiled on accusations of plotting regicide, a charge many suspect was fabricated by the Egyptian queen herself. Not long after, Arsinoe married her brother and ascended as queen of Egypt.
8 A Purge Of Ptolemies
Ptolemaic Egypt reached its zenith under Ptolemy III Euergetes, whose triumphs in the Third Syrian War marked a golden age. The subsequent reign of his son, Ptolemy IV Philopator, signalled the onset of decline, as historians portray him as a weak monarch easily swayed by indulgent courtiers.
Ascending the throne in 221 BC at twenty‑three, Ptolemy IV devoted himself to a life of excess, delegating the administration to his chief minister, Sosibius. The Greek historian Polybius records that Sosibius orchestrated the murders of several close relatives, including Ptolemy’s mother, Berenice II, his brother Magas, and his uncle Lysimachus.
Following the pattern of his forebears, Ptolemy IV married his sister Arsinoe III. After his death in 204 BC, Sosibius and another official, Agathocles, arranged for Arsinoe III’s death, ensuring they could act as regents for the under‑age Ptolemy V.
7 Anything For Power
Numerous members of the Ptolemaic line displayed a willingness to commit ruthless acts to seize power, but few matched the savagery of Ptolemy VIII Physcon.
Physcon endured a protracted struggle for the throne against his elder brother, Ptolemy VI Philometor. In 145 BC the older brother fell in battle, prompting his sister‑wife Cleopatra II to push for her young son, Ptolemy VII Neos Philopator, to assume rulership.
The exact nature of Physcon’s reign remains a point of scholarly debate; some contend he never truly ruled. If he did, his tenure was brief, as Cleopatra was forced to marry him and share power. Once Neos Philopator was deposed, Physcon ordered his execution.
Having secured the throne, Physcon rechristened himself Ptolemy Euergetes, echoing an illustrious ancestor. He wed his niece, Cleopatra III, while still married to her mother—a tangled family web typical of the dynasty.
In 131 BC, Cleopatra II orchestrated a rebellion that forced Physcon to flee Alexandria with Cleopatra III. They spent four years in exile on Cyprus, during which Cleopatra II acted as regent for her son, Ptolemy Memphites, who never came of age because Physcon eventually reunited with his son only to murder him.
Physcon then displayed a gruesome display of power: he severed the boy’s head, hands, and legs, sending the dismembered limbs to Alexandria on Cleopatra’s birthday. Despite these barbaric acts, the siblings eventually reconciled publicly, governing jointly alongside Cleopatra III until Physcon’s death in 116 BC.
6 Violent Ends For Violent People
The brief yet ferocious reign of Ptolemy XI Alexander II stands out as a stark blemish on the three‑century Ptolemaic saga.
He succeeded his father, Ptolemy X Alexander I, in 80 BC and took as wife—also his cousin—Berenice III, who had briefly ruled alone and won the affection of the Egyptian populace.
However, the newly‑wedded pharaoh grew hostile toward his wife. Within three weeks of their marriage, he ordered Berenice’s assassination. The public outrage was swift: an Alexandrian mob stormed the palace gymnasium and killed the young king.
5 Rome Intervenes
Ptolemy XII Auletes claimed the throne in 80 BC, at a time when Egypt had become a Roman client state, obliged to pay a hefty tribute that imposed crushing taxes on its citizens.
In 58 BC, Rome seized Cyprus, and Ptolemy’s brother—the King of Cyprus—committed suicide. The Egyptian populace demanded that Ptolemy either demand the return of Cyprus or renounce Rome’s dominance, but he refused both, prompting a rebellion that forced him into exile.
Seeking refuge, he fled to Rome and lodged with the powerful general Pompey. While in the capital, discussions erupted in the Senate about restoring him to power in Egypt.
A delegation of one hundred Egyptians, led by the philosopher Dio of Alexandria, prepared to present their grievances before the Senate, hoping to secure aid for their ousted monarch.
Yet Auletes leveraged his wealth and Pompey’s connections to sabotage the mission: most of the envoys were murdered—including Dio—while the few survivors were bought off with bribes.
Although violence solved the messenger problem, a divine dilemma persisted. The Romans, in typical crisis fashion, consulted the Sibylline Books, a collection of prophetic sayings.
The Sibylline prophecy warned, “If the king of Egypt comes requesting any aid, refuse him not friendship, nor yet succour him with any great force; else you shall have both toils and dangers.”
4 The March Gabinius
The Sibylline injunction led the Senate to deny military assistance to Ptolemy, yet avarice ultimately overrode the prophetic counsel. Pompey dispatched his lieutenant, Aulus Gabinius, to invade Egypt without Senate approval—a risk the powerful general could afford.
During Ptolemy’s exile, his daughter Berenice IV assumed the throne. She attempted to cement an alliance by marrying Seleucus of Syria, only to have him slain and then wed Archelaus.
Archelaus perished when Gabinius seized Alexandria. The Roman general reinstated Ptolemy, leaving behind a Roman legion to safeguard the restored king, a force later known as the Gabiniani.
Back on the Egyptian throne, Ptolemy ordered the execution of his own daughter. He also plundered the wealth of the realm’s richest citizens to settle the massive debt he owed to Gabinius and Pompey.
Gabinius’s triumph was short‑lived. The Roman populace condemned his defiance of the Sibylline warnings and the Senate, leading to his arrest upon return to Rome on charges of high treason.
Through generous bribery and political maneuvering, Gabinius was acquitted of the most serious charge, though he was later convicted of lesser offenses, exiled, and had his property confiscated.
3 The Murder Of Pompey
In 52 BC, Ptolemy XII appointed his daughter Cleopatra VII Philopator as co‑regent, hoping she would share power with her brother Ptolemy XIII Theos Philopator. Both siblings, however, sought Roman backing.
At that juncture, Julius Caesar was locked in a civil war that would topple the Republic, having just secured a decisive victory over Pompey at Pharsalus.
Pompey, seeking refuge and support, sailed to Egypt, expecting the familiar hospitality his father had once received from Ptolemy XIII. Yet Ptolemy, eager to curry favor with Caesar, chose a different path.
He dispatched a contingent to greet Pompey under the pretense of friendship, but the men seized the opportunity to stab, decapitate, and discard Pompey’s body into the Nile. Ancient sources name two Gabiniani—former tribune Lucius Septimius and centurion Salvius—alongside Egyptian commander Achillas as the perpetrators.
The gruesome act backfired spectacularly: Caesar, presented with Pompey’s severed head and his signet ring, was reportedly moved to tears, expressing disgust at the treacherous murder.
2 War Of The Ptolemies
Whether Pompey’s assassination swayed Caesar remains uncertain, yet the Roman leader threw his weight behind Cleopatra. Lacking sufficient troops for open warfare, Caesar entrenched himself within Alexandria in 47 BC as Ptolemy’s forces, led by Achillas, laid siege to the city.
Another child of Ptolemy XII, Arsinoe IV, entered the fray, asserting her claim to the throne by siding with her brother Ptolemy XIII. She ordered the execution of Achillas, replacing him with her tutor Ganymedes.
Eventually, Caesar received reinforcements from his ally Mithridates of Pergamum, securing a decisive victory at the Battle of the Nile in 47 BC. Ptolemy XIII drowned in the river at the age of fifteen, while Arsinoe IV was first paraded through Rome as a captive and later exiled to the Temple of Artemis in Ephesus, only to be executed at Cleopatra’s behest.
1 The End Of The Dynasty
Cleopatra reclaimed the Egyptian throne, yet Julius Caesar arranged for her to rule jointly with her younger brother, Ptolemy XIV. Their marriage was fleeting; in March 44 BC Caesar was assassinated in Rome. Two months later, Ptolemy XIV died under mysterious circumstances, with historians such as Cassius Dio and Josephus suggesting Cleopatra poisoned him to elevate her son, Ptolemy XV Philopator Philometor Caesar—better known as Caesarion—as the new ruler.
If Cleopatra indeed orchestrated his death, it was to secure Caesarion’s position as pharaoh, proudly branding him as Julius Caesar’s offspring.
With Caesar gone, Cleopatra turned to Marcus Antony, a member of the Second Triumvirate governing Rome. In 34 BC Antony issued the Donations of Alexandria, granting lands and titles to Cleopatra’s children, as well as to three of his own offspring.
Crucially, Antony recognized Caesarion as the legitimate heir of Julius Caesar, a move that enraged the Roman establishment, which saw Antony as abandoning Roman interests for Egyptian influence. Octavian, Caesar’s adopted son, perceived Caesarion as a direct threat.
War erupted between Antony and Octavian, culminating in Octavian’s triumph at the Battle of Actium and the subsequent siege of Alexandria. Antony and Cleopatra allegedly committed suicide, while Octavian ordered Caesarion’s execution.
Following these events, Egypt was annexed as a Roman province. Octavian, now Augustus Caesar, became the first Roman emperor, marking the definitive end of the Ptolemaic dynasty.
