Saint Valentine is said to have lived in Rome during the third century. That was a long time ago. During this time Rome was ruled by an emperor named Claudius. Many people did not like the ruler.

Claudius was having trouble getting men to serve in his army. He felt many men would not volunteer to join because they did not want to leave their wives and families. He thought that if men were not married, they would join the army. So Claudius passed a new law which did not allow any more marriages. Most people thought this law was cruel. Valentine, who was a minister, did not support the new law.

Even after Emperor Claudius passed the law, he kept performing marriage ceremonies secretly. One night he was caught and thrown in jail and told he would be put to death.

Many young people came to visit Valentine. One was the daughter of the prison guard. On the day of his death Valentine wrote a note to the daughter signed "Love from your Valentine". This was on February 14, 269 A. D.

Some say this started the custom of exchanging love messages on Valentine's Day.
