A long, long, long time ago, Valentine's Day wasn't just about candy hearts and red roses (shocking, we know).
Feb. 14 actually celebrates a historic, and somewhat tragic event steeped in religious controversy. Saint Valentine -- the original romantic -- gave significance to the holiday, now known more for its Hallmark value.
But back in the day, Valentine was just a man who really believed in love and marriage. So before you start ordering those heart-shaped Etsy cards and buying chocolates, take a minute and watch this video to learn how you're taking part in a tradition centuries in the making.
