How was Valentine's Day created?

Pope Gelasius I technically invented Valentine's Day in AD 496 when he established The Feast of Saint Valentine, in memory of the martyred saint who died on that day over 200 years before. It originated as a Christian feast day honoring one or two early Christian martyrs named Saint Valentine and, through later folk traditions, has become a significant cultural, religious, and commercial celebration of romance and love in many regions of the world.
