The Roman Emperor Claudius was having trouble getting men to serve in his army so he passed a law which did not allow any more marriages. (Single men were more willing to go off to war)
Valentine, who was a minister who did not support the new law, was caught performing marriage ceremonies secretly. Jailed and sentenced 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 allegedly happened on 14th february 269
