St. Valentine's Day has its origins in ancient Roman traditions celebrating fertility and love. One legend says that St. Valentine was a priest in Rome during the 3rd century who secretly married couples despite Emperor Claudius II's ban, for which he was put to death. Another story suggests Valentine helped Christians escape prisons and may have sent the first "valentine" greeting to a girl he fell in love with while imprisoned. By the Middle Ages, Valentine had become one of the most popular saints in England and France due to his reputation as a sympathetic, heroic, and romantic figure.
