Saint Valentine was a priest who secretly married couples against the orders of Emperor Claudius II. When the emperor discovered Saint Valentine's actions, he had Saint Valentine imprisoned and sentenced to death. While in prison, Saint Valentine fell in love with the jailor's daughter and sent her a farewell love letter signed "Your Valentine" before his death. Today on February 14th, Valentine's Day is celebrated in many countries with the exchanging of cards, flowers, and gifts as a tribute to Saint Valentine and as a way to express love and affection.
