Saint Valentine was Bishop of Interamna during the reign of Claudius II who did away with marriage. In secret Valentine continued to marry couples. On the 14th February 270AD Valentine was put to death for refusing to renounce his faith in Christ.
Valentine's Day is said to be named after Saint Valentine. The Catholic Church recognizes at least three different saints named Valentine or Valentinus, all of whom were martyred. One legend contends that Valentine was a priest who served during the third century in Rome. When Emperor Claudius II decided that single men made better soldiers than those with wives and families, he outlawed marriage for young men. Valentine, realizing the injustice of the decree, defied Claudius and continued to perform marriages for young lovers in secret. When Valentine's actions were discovered, Claudius ordered that he be put to death.
The Roman Emperor, Claudius II Gothicus, was having problems raising an army as Roman law forbade drafting married men. He decided to outlaw marriage to get around this problem. Valentine continued to marry couples in secret. When Claudius found out, he had Valentine arrested and thrown into prison where he was tortured and beheaded.
The one fact that can be stated confidently is that we know nothing about the legendary Saint Valentine, not even whether he actually existed. Wikipedia says that it is uncertain whether St. Valentine is to be identified as one saint or the conflation of two saints of the same name, which if true would militate against any tradition that he was imprisoned or executed on a particular day. Nevertheless tradition says that he died on February 14, 273 on Via Flaminia in the north of Rome. When, in 496, Pope Gelasius included Valentine among all those "... whose names are justly reverenced among men, but whose acts are known only to God," Gelasius implies that, in his time, nothing was known about the life of Valentine. Subsequent tradition speaks of St. Valentine being arrested for secretly marrying young couples so that the husbands could avoid military service. This tradition usually asserts that Saint Valentine was tortured and beheaded.
In Christianity, there are some famous martyrs, some examples are: Jesus, John the Baptist, Saint Valentine, who was put to death by the Romans for secretly wedding Christians back when Christians were being condemned by the Roman Empire.

February 14th is the Feast of Saint Valentinus (Valentine). Valentinus was a Catholic priest who was martyred (beheaded) on February 14 in 270 CE at the order of Claudius II.

Not everyone agrees who St. Valentine really was. One of the theories claims that Valentine was a priest, who served in third century Rome. Emperor Claudius II believed that single men made better soldiers, so he outlawed marriage for young men. Valentine defied Claudius and continued to perform marriages for young lovers in secret. He was later put to death for his actions. Some believe St. Valentine actually sent the very first Valentine's Day card. While locked up in prison, it is believed that Valentine fell in love with the jailer's daughter. Before his death, it is said that he wrote her a letter, which he signed 'From your Valentine.'
