In the ancient Roman calendar, before the Christian Era, every month had three named days: the Calends (or Kalends), the first day of the month when accounts were due; the Nones, the fifth or seventh day of the month; and the Ides, the middle of the month (between the 13th to 15th day). There was nothing particularly significant about the ides of January, the ides of February, and so forth.
All that changed in 1599 when William Shakespeare wrote The Tragedy of Julius Ceasar. In Act 1, Scene 2, in a public place on March 15th, 44 BC, a soothsayer among the crowd approaches Caesar and calls out: “Caesar!… Beware the ides of March.” Caesar is not sure he has heard the man correctly, so Brutus repeats it: “A soothsayer bids you beware the ides of March.” The soothsayer repeats the line, warning that the Roman leader’s life is in danger. But Caesar immediately dismisses him: “He is a dreamer; let us leave him: pass.” As we all know, Caesar should have heeded the soothsayer’s warning. In a scene filled with brutality and treachery, Caesar is surrounded by an angry mob of senators who walk up to him and stab him to death. He is stabbed a total of 23 times. As his life slips away, a feeble Caesar turns to his closest friend and ally, Marcus Junius Brutus, and utters the famous line, “Et tu, Brute?” (you too, Brutus?), signifying the ultimate betrayal.
So from that point on, thanks to Shakespeare’s dramatic genius, the phrase “Beware the Ides of March” being linked to Caesar’s barbarous assassination, imbued upon March 15 a rather ominous and nefarious connotation that has been passed down through the centuries. However, Tom Frail, senior editor of Smithsonian magazine, notes that March 15th lives in infamy beyond Casear’s murder. He cites several events in history that occurred on that same fateful day that were filled with villainy or mortalities:
Raid on Southern England, March 15, 1360: The French raided a town in southern England and began a two-day spree of murder, rape, and pillage. King Edward III initiated a pillaging spree in France in retaliation.
