'Beware the Ides of March.' Thanks to William Shakespeare, March 15 has become one of the most famous dates in history. The Ides of March marks the day in 44 BC when Roman dictator Julius Caesar was assassinated by a group of senators in Rome. Today, it is remembered as a turning point in Roman history and as a byword for betrayal and bad luck, though for the Romans it was originally just a normal date on the calendar.
History of Ides of March
The Romans did not number days the way we do. Each month had three key dates: the Kalends (the first day), the Nones (the 5th or 7th) and the Ides (the 13th or 15th). The Ides marked roughly the middle of the month and were linked to the full moon. In March, May, July and October, the Ides fell on the 15th. The Ides of March was also a deadline for settling debts in ancient Rome.
By 44 BC, Julius Caesar had become dictator for life, alarming many senators who feared he would end the Roman Republic. On March 15, a group led by Marcus Brutus and Gaius Cassius stabbed Caesar to death at a meeting of the Senate. According to ancient writers, a seer had warned Caesar to beware the Ides of March.
Instead of saving the Republic, the assassination led to civil war and, eventually, to the rise of Caesar's heir Octavian as Augustus, the first Roman emperor. Shakespeare's play Julius Caesar, written around 1599, made the warning famous.
Why Ides of March Matters
The Ides of March marks a pivotal moment that helped transform Rome from a republic into an empire, a story that still shapes discussions about power and democracy.
