Julius Caesar was about 55 years old when he was assassinated on March 15, 44 BCE. Most modern reference works place his birth on July 12 or 13, 100 BCE. Because his birthday in 44 BCE had not yet arrived, that chronology makes him 55 at the time of his death.
When was Julius Caesar born?
Caesar’s birth is usually dated to July 12 or 13, 100 BCE, in Rome. Ancient chronological evidence is not perfectly uniform, and older scholarship sometimes proposed 102 BCE. Modern historical reference works generally use 100 BCE, which also fits the age normally given for him at his assassination.
When and how did Caesar die?
Caesar was killed on the Ides of March, March 15, 44 BCE, during a meeting of the Roman Senate held in the complex of Pompey’s Theatre. A group of senators, including Marcus Junius Brutus and Gaius Cassius Longinus, attacked him because they feared that his concentration of power threatened the republican political order.
By then Caesar had emerged from civil war as Rome’s dominant political figure and had received the title dictator perpetuo, or dictator in perpetuity. His assassination did not restore lasting republican stability. Instead, it was followed by further civil wars that eventually brought Octavian, the future Augustus, to supreme power.
Why do some sources give a different age?
Ancient dates can be difficult to reconcile because Roman authors did not always preserve birthdays and ages consistently. A birth year of 100 BCE produces an age of 55 in March 44 BCE; a birth year of 102 BCE would make Caesar older. The 100 BCE date is now the standard date used in most modern biographies.
It is also worth remembering that BCE dating moves backward toward year 1 BCE. There is no year zero in the traditional BCE/CE system, so simple subtraction can be misleading if the exact month and day are ignored.
Why Caesar’s age matters historically
Caesar’s death came when he was still actively reshaping Roman government, law, provincial administration, and the calendar. His career had included the conquest of Gaul, victory in civil war, and sweeping reforms in Rome. At roughly 55, he was neither an elderly ruler withdrawing from public life nor a young revolutionary at the beginning of his career. His assassination interrupted an established but still evolving political program.
