'Beware the Ides of March' -- What does that mean?

Tensions had been simmering between senators and Caesar before his death, fueled by Caesar's continued consolidation of power. However, Caesar considered the senators his allies. Just a few years before his death, Caesar was named “dictator in perpetuity,” a move that further strained relations.

According to historians, sixty senators planned and participated in the conspiracy to kill Caesar in 44 B.C.

Death marked a turning point in Roman history

Caesar was popular with the lower class people of Rome, who saw his death as an unwelcome decision made by the aristocratic class. With Caesar no longer leading, potential leaders waged war to fill the power vacuum.

The civil wars eventually culminated in the end of the Roman Republic and beginning of the Roman Empire.

'Beware the Ides of March' made famous by Shakespeare

In case you really did forget your high school English class, it's worth noting the phrase “Beware the Ides of March” was immortalized by William Shakespeare in his tragic masterpiece “Julius Caesar.”

In the play, a soothsayer warns Caesar to be careful on March 15, although the ruler ignores the mystic with tragic consequences.

Famous line based on historical events

It may come as a surprise to know the well-known phrase was actually inspired by real events.

According to Greek historian Plutarch, a seer really did warn Caesar that he would be at the very least injured by the Ides of March.

Caesar did not heed the warning.

On the day of his death, he saw the oracle and joked that he had made it to the Ides of March, to which the seer responded the day had not yet ended.

So why is it called the "Ides of March?"

The Romans kept track of days on its calendar by dividing each month up into three separate points marking the beginning, middle and end of the month. You may have guessed it but the Ides fall in the middle of the month, on the 15th of March, May, July and October and the 13th for the rest of the year.

The Ides were sacred and marked a monthly sacrifice to the Roman god Jupiter. Various other religious observances also took place on the Ides of March.
