Although no one knows for certain who the original Saint Valentine was, once a year, on February 14, there is a day in his honor. Some historians believe that the original Saint Valentine was a priest who lived in the city of Rome about 300 years after the birth of Christ. The emperor of Rome was not a Christian and refused to allow people to be married in a Christian ceremony. Saint Valentine didn’t obey the emperor and performed many Christian marriages in spite of the emperor’s order. When the Romans found out, they sent Saint Valentine to prison and later killed him. While his romantic efforts to help many Christians in love cost him his life, he was honored in his own days.
