Every February 14, couples across the United States splurge on fancy dinners and exchange overpriced jewelry to celebrate St. Valentine., But who is this Saint and where did these rituals come from?

The most popular legend goes like this: Valentine’s Day derives from both Christian and ancient Roman tradition. During the third century of Rome, Valentine served as a priest under the rule of Emperor Claudius II. The Emperor decided that single men made better soldiers without wives and families, and outlawed marriage for men. Valentine realized this absurdity, and defied Claudius, continuing to perform marriages for young lovers in secret. Unfortunately, when Claudius discovered Valentine’s disobeyment, he ordered Valentine to be put to death.

Another legend suggests that Valentine was imprisoned from attempting to help Christians escape harsh Roman prisons, where they were tortured and beaten. After falling in love with the jailer’s daughter, Valentine actually sent her the first “valentine” greeting himself when she visited him during his confinement. In fact, he signed it with “From your Valentine,” an expression that is still in use today.

In addition to the United States, Valentine’s Day is celebrated in Canada, Mexico, the United Kingdom, Australia and France. In Finland, Valentine’s Day is called Ystävänpäivä, which translates into “Friend’s day”, and is about  remembering your buddies more than your loved ones.

Although the Valentine’s legends are varied and the truth is murky, all stories emphasize his appeal as a heroic and romantic figure. He died on Feb. 14, therefore creating the romantic reputation and holiday we still celebrate centuries later.
