Cards, flowers, and candy, are just a few ways to describe how people celebrate St. Valentine’s Day every year on February 14. But where did Valentine’s Day originate from?

According to History.com, the holiday is named after St. Valentine, but there are a few legends as to who he was. One of them depicts Valentine as a Roman priest who performed marriages even after it had been forbidden. As a result of his actions, he was killed.

Another story depicts Valentine as an imprisoned man who fell in love with a young girl who visited him while he was in prison. He sent her the first valentine greeting and right before his death, it is said that he wrote a letter to her and signed it with “from your valentine.”

Some people believe that Valentine’s Day is celebrated in mid-February to honor the death of St. Valentine, but others claim that the Christian church may have chosen to celebrate Valentine’s Day in mid-February to try and “Christianize” the ancient Roman festival of Lupercalia.

Lupercalia was a fertility festival celebrated from February 13 to February 15. At the end of the fifth century, Pope Gelasius put an end to the festival by declaring February 14 St. Valentine’s Day. It wasn’t long after that the holiday became associated with love.

Some people, however, are skeptical of how Valentine’s Day came to be. They believe that it was a holiday created by Hallmark.
