But the rise of Christianity in Europe saw many pagan holidays being renamed for and dedicated to the early Christian martyrs. In 496 AD, Pope Gelasius turned Lupercalia into a Christian feast day and set its observance a day earlier, on February 14. According to the Catholic Encyclopedia, there were at least three early Christian saints by the name of Valentine. Surprisingly, all three of them were said to have been martyred on 14th February.
He proclaimed February 14 to be the feast day in honor of Saint Valentine, a Roman martyr who lived in the 3rd century. While one was a priest in Rome, another was a bishop in Terni. It is clear that Pope Gelasius intended to honor the first of these three aforementioned men. Valentine was a priest who lived around 270 AD in Rome and attracted the disfavor of Roman emperor Claudius II who ruled during this time. Valentine has two different versions - the Protestant and the Catholic one.
The Roman empire faced crisis from all sides, from the Gauls, Slavs, Huns, Turks and Mongolians from Northern Europe and Asia.
The empire had grown too large to be shielded from external aggression and internal chaos with existing forces.
There hardly seems to be a young man or woman who is not keen to make the most of the day.
The history of Valentine's Day is impossible to be obtained from any archive and the veil of centuries gone by has made the origin behind this day more difficult to trace.
And thus he secretly performed many marriages for young lovers. It was only a matter of time before Claudius came to know of this "friend of lovers," and had him arrested.
While awaiting his sentence in prison, Valentine was approached by his jailor, Asterius.
Lack of quality administrators led to frequent civil strife.
Education declined, taxation increased and trade witnessed a very bad time.
