“Beware the Ides of March.”
You may hear that phrase today because the 15th of March is referred to as the ‘Ides of March’ and marks the anniversary of the assassination of Julius Caesar in 44 BC.
Gaius Julius Caesar was a Roman general, Consul, statesman, and notable author of Latin prose. He was both a conquering hero and a dictator. He played an essential role in the history of Ancient Rome, acting out pivotal parts in events that led to the demise of the Republic and the rise of the Empire.
Caesar started off as an accomplished military man, fighting for the glory of Rome. He was able to extend Roman territory to the English channel and the Rhine in his conquest of Gaul, completed by 51 BC.
He became the first Roman general to invade Britain.

His achievements awarded him the position of an unmatched military prowess, but also threatened to eclipse the role of Pompey, the military and political leader of the late Roman Republic. Pompey, who had previously held an alliance with Caesar and Crassus, had realigned himself with the senate after Crassus’ death in 53 BC.
When the Gallic wars had finished, the Senate ordered Caesar to lay down his weapons and commanded him to return to Rome. Caesar, however, refused. In 49 BC he crossed the Rubicon with a legion. This was the moment that marked his defiance; he had left his province and illegally entered Roman territory, bearing arms. A civil war ensued, but Caesar emerged as the unrivaled leader of Rome.
Caesar assumed control of the government and then proceeded to install a program of social and governmental reforms, such as the creation of the Julian Calendar. He centralised the bureaucracy of the Republic and eventually was proclaimed “dictator in perpetuity”.
Caesar, however, was not popular with everyone – especially the politicos he had ignored.
On March 15th, 44 BC, the Ides of March, Caesar was stabbed to death at a senate meeting.
According to Plutarch, Caesar had been told that this would come to pass. A seer had warned Caesar that harm would come to him, no later than the Ides on March. Then on that fateful day, Caesar passed the prophesier on his walk to the Theatre of Pompey, the place were he would be murdered. He quipped, “The ides of March have come”, thinking that the morbid prophecy had not been fulfilled.
To this the seer replied, “Aye, Caesar; but not gone.”
Beware the Ides of March
It is thought that as many as 60 conspirators were involved in the assassination, led by Brutus and Cassius. This scene, as dramatized by William Shakespeare has given us the famous lines, “Beware the Ides of March” and “Et tu, Brute?”
Whether the date was, in fact, the 15th of March is up to debate, as the Roman calendar was structured differently from our modern calendars. For one thing, they only had 10 months. Additionally, the Romans did not number the days of the month sequentially from the first to the last. They actually counted back from three fixed points with in the month and varied depending on the length of the month. These included the Nones (5th or 7th), the Ides (13th or 15th), and the Kalends (1st of the following month).
The Ides occurred on the 15th for March, May, July and October, and were supposed to be determined by the full moon. (This reflects the lunar origins of the Roman calendar).
