September 28
Pompey the Great Assassinated in Egypt
Betrayed by the Egyptian court he had once supported, Pompey the Great was struck down upon landing at Pelusium, ending his flight from Caesar’s victory at Pharsalus.
Summary
In the final stages of the Roman civil war, Gnaeus Pompeius Magnus, known as Pompey the Great, had suffered a decisive defeat at the Battle of Pharsalus against Julius Caesar in August 48 BC. Fleeing eastward, Pompey sought refuge and support from King Ptolemy XIII of Egypt, whose father had once been aided by the Roman general. Upon arriving near Pelusium on September 28, 48 BC, Pompey was invited ashore by Egyptian officials. As he stepped from his boat, he was treacherously attacked and killed by Roman officer Lucius Septimius and others acting on Ptolemy's orders. His head was severed and presented to Caesar later as a grim trophy, while his body was cremated on the shore. This murder eliminated a major rival and cleared the path for Caesar's dominance in Rome, though it also drew him into Egyptian affairs.
Context
By the mid-first century BC, Rome’s republican institutions strained under the ambitions of powerful generals who commanded loyal legions and vast client networks across the Mediterranean. Pompey had risen through a series of extraordinary commands, defeating pirates, conquering eastern kingdoms, and reorganizing Roman territories from Armenia to Judea. In 60 BC he joined Julius Caesar and Marcus Licinius Crassus in an informal alliance known as the First Triumvirate, which dominated Roman politics for several years until personal rivalries and the deaths of Crassus and Pompey’s wife Julia fractured the partnership.
What Happened
After Caesar’s legions routed Pompey’s larger army at the Battle of Pharsalus in central Greece in August 48 BC, the defeated general escaped eastward with a small entourage. He sailed first to Cyprus and then toward Egypt, hoping that the young King Ptolemy XIII would honor the longstanding ties his father, Ptolemy XII, had maintained with Rome and with Pompey personally. On 28 September Pompey’s ships reached the Egyptian coast near the fortress city of Pelusium, where Ptolemy’s army was encamped amid a dynastic struggle with his sister Cleopatra VII.
Aftermath
Egyptian officials rowed out to invite Pompey ashore for an audience. As he stepped from the boat, the Roman renegade Lucius Septimius, serving in Ptolemy’s army, and two Egyptian officers, Achillas and Salvius, attacked him. Pompey was killed on the beach; his head was severed and his body was later cremated by loyal servants. When Caesar arrived in Egypt a few days later, Ptolemy’s courtiers presented him with the head as proof of loyalty, but the gesture only drew Caesar deeper into Egyptian politics.
Legacy
The murder removed Caesar’s last major rival and hastened the collapse of the republican order that had endured for centuries. Caesar’s subsequent intervention in Egypt, the Alexandrian War, and his liaison with Cleopatra further entangled Roman power in the Hellenistic East. Historians from Plutarch onward have viewed Pompey’s death as emblematic of the personal betrayals and shifting alliances that ultimately transformed the Roman Republic into an autocratic empire under one man.
Why It Matters
The assassination ended the First Triumvirate era and accelerated Caesar's rise to dictatorship, reshaping the Roman Republic into an empire. It underscored the volatile alliances and betrayals that defined late Republican politics, influencing subsequent civil conflicts and the consolidation of power under one ruler.
