According to history, the Romans celebrated a festival called Lupercalia. It was celebrated from 13th to 15th of February as a fertility festival dedicated to the Roman god of agriculture.
During the festival, boys will draw a girls name from a jar and the pair will be together throughout the festival. It could even lead to marriage so they celebrated this as a season of love as young men get the opportunity to be with young girl, and made romance with them.
Apart from this, it is recorded that the festival is celebrated in honour of a Roman priest named St. Valentine. He was a priest who arranged weddings for lovers illegally after the Roman Emperor in the third century had banned marriage so that young men could become better soldiers in Empire.
When the emperor heard what he was doing, he had him put to jail. As he was in jail, he fell in love with a girl said to be the daughter of his jailer. He was to be executed then he wrote a departure letter to the girl he fell in love with and addressed it as "From Your Valentine"
14th February was the day he was executed.
Others believed that the early Catholic churches celebrated this festival on 14 February, to Christianise the pagan festival Lupercalia.
