“Beware the Ides of March,” which happens to be today. March 15 marks the anniversary of Julius Caesar’s death, when Marcus Junius Brutus and other senators assassinated him. The 44 B.C. event has not been forgotten and is now associated with loyalty and betrayal.

The Ides of March seems like the perfect time to look at some favorite quotes about loyalty from William Shakespeare, who wrote the famous “beware the Ides of March” line, and other famous authors (via GoodReads).

“I used to advertise my loyalty and I don’t believe there is a single person I loved that I didn’t eventually betray.” ― Albert Camus, “The Fall”

“I belong to the people I love, and they belong to me ― they, and the love and loyalty I give them, form my identity far more than any word or group ever could.” ― Veronica Roth, “Allegiant”

“Master, go on, and I will follow thee

To the last gasp with truth and loyalty.” ― William Shakespeare, “As You Like It”

“If I mistake not, a strong sense of duty is no bad part of a woman’s portion.” ― Jane Austen, “Persuasion”

“We have to recognize that there cannot be relationships unless there is commitment, unless there is loyalty, unless there is love, patience, persistence.” ― Cornel West, “Breaking Bread: Insurgent Black Intellectual Life”

“‘Faithless is he that says farewell when the road darkens,’ said Gimli.” ― J.R.R. Tolkien, “The Fellowship of the Ring”

“Unlike the puerile loyalty to a conviction, loyalty to a friend is a virtue ― perhaps the only virtue, the last remaining one.” ― Milan Kundera, “Encounter”
