Throughout the ages, poison has been the silent assassin’s favorite tool. It may lack the drama of a sword, but its quiet lethality made it perfect for covert power plays, especially when wars and murders demanded utmost discretion.
10 notable poisonings in antiquity
10 Socrates
No discussion of historic poisonings would be complete without the famed case of Socrates. Though he drank the cup himself, declaring a longing for death after a lifetime of contemplation, the philosopher was essentially forced into the act while imprisoned in Athens. The city needed a scapegoat to placate political unrest, and Socrates—unpopular and outspoken—fit the bill perfectly.
Regarded both as a laughingstock and a brilliant mind capable of turning the tables on his detractors, Socrates became a convenient target for political vengeance. He was compelled to accept an unjust charge, pay a fine, and either flee—which his conscience forbade—or sip the poison under Athenian pressure. Thanks to Plato’s accounts, his philosophical legacy survived, forever altering Western thought.
9 Drusus Julius Caesar
This would‑be emperor, the sole son of Tiberius, stood poised to inherit the Roman throne in the 20s AD. A moderately experienced statesman with a promising future, his lineage linked him to the notorious reigns of Nero and Caligula. Yet his balanced temperament and reputation for violence made him a prime target for political machinations.
Sejanus, a power‑hungry confidant of Tiberius, dreaded Drusus’s succession. Seducing Drusus’s wife Livilla with promises of divorce, Sejanus set the stage for betrayal. Livilla administered poison, ending Drusus’s life. When Tiberius eventually passed, the crown fell to the infamous Caligula instead.
8 Demosthenes Of Athens
Demosthenes, the celebrated Athenian orator, fiercely opposed the Macedonian expansion under Philip II and later Alexander the Great. He championed Athenian democracy, delivering impassioned speeches to rally his fellow citizens against Macedonian annexation.
After Philip’s sudden death, Alexander seized power. Demosthenes attempted an uprising, which failed, leading to his exile. When Alexander later died, Demosthenes’s friend Demades branded him a traitor, and the Athenian assembly sentenced him to death. Choosing his own fate, Demosthenes consumed poison, ending his tragic saga.
7 Cleopatra
Cleopatra VII Philopator, perhaps the most renowned woman in antiquity, met her end through poison. Ascending to power via her Macedonian ancestry, she became a literary icon, especially after Shakespeare dramatized her life.
She famously rolled herself in a rug to gain an audience with Julius Caesar, leveraging the encounter for political gain. Later, her liaison with Mark Antony cemented her influence, yet their alliance angered Rome’s elite. When Octavian threatened capture, Cleopatra allegedly spread rumors of her own suicide, prompting Antony to kill himself under the false belief she was dead. She then chose hemlock—though legend often cites an asp’s venom—to avoid capture.
6 Artaxerxes III
Beyond the Greco‑Roman sphere, the Persian Empire witnessed its own share of lethal intrigue. Artaxerxes III, a ruler from a long line of monarchs, governed with an iron grip, eliminating rivals—including family members—to secure his reign.
In a classic double‑cross, his trusted minister Bagoas slipped poison into Artaxerxes’s cup, killing the king and all his sons save one. Bagoas later attempted, unsuccessfully, to poison Darius III, illustrating how poison served as a political weapon in Persia.
5 Artaxerxes IV
The saga continued with Artaxerxes IV, also known as Arses, who was the lone surviving son of Artaxerxes III. Bagoas, eager to manipulate the throne, elevated Arses to power, hoping to pull the strings from behind the scenes.
However, Arses plotted to poison his benefactor Bagoas after only two years as king. The plan backfired; Bagoas administered the poison himself, killing Arses and installing his cousin Darius III as the new emperor, perpetuating the cycle of treachery.
4 Bagoas
Revenge can taste bitterly sweet. Bagoas, a behind‑the‑scenes power broker, orchestrated the murders of both Artaxerxes III and IV, using poison to eliminate anyone who didn’t serve his agenda. He then placed Darius III on the throne, believing he could control the new ruler.
When Bagoas later tried to poison Darius III, the emperor was forewarned. Darius turned the tables, forcing Bagoas to drink the very poison intended for him. Thus, Bagoas met his end by his own lethal concoction.
3 Antipater
Antipater, the father of Herod the Great, founded a dynasty in Palestine that would later be chronicled in the Bible. Caught in a whirlwind of local Jewish and non‑Jewish politics, he was installed by Caesar and Pompey, intertwining his fate with Roman power struggles.
During his rise, Antipater alienated the local king Aristobulus and sidelined Hyrcanus II, installing his own sons—including Herod—into key positions. A political rival named Malich (or Malichus) eventually poisoned Antipater, a move that also benefited Hyrcanus. Despite this, Herod secured Roman backing and rose to become the biblical king.
2 Claudius
Emperor Claudius, son of Nero Claudius Drusus Tiberius, greatly expanded Rome, even annexing Britain. His reign from AD 41 to 54 was marked by military success and relative stability.
His marriage to Messalina produced a son, Brittanicus, but political intrigue soon followed. Claudius discovered that his wife Messalina was conspiring against him, leading to a divorce. He then wed Agrippina the Younger, mother of the future emperor Nero. Seeking to secure Nero’s succession, Agrippina slipped poison into Claudius’s cup, ensuring Nero’s rise to power.
1 Britannicus
Nero’s path to the throne was blocked by Britannicus, the rightful heir following Claudius’s death. Britannicus, the son of Claudius and his former wife Messalina, represented a legitimate claim that threatened Nero’s ambitions.
Agrippina the Younger, already responsible for Claudius’s murder, hired the same poisoner to eliminate Britannicus. The young prince died at just thirteen, clearing Nero’s way to the imperial seat. However, Nero’s reign would later see him turn on his own mother, Agrippina, completing a grim cycle of familial poisonings.
