Although everyone celebrates this day, most people have no idea why it is celebrated and where it originated. However, there are various stories behind it, but one of the most well-known is the story of early Christian martyrs named Saint Valentine.
He was the Roman priest who secretly arranged marriage in violation of Emperor Claudius II’s rules (who had forbidden marriage since he considered married men were bad soldiers). As a result, he was imprisoned and sentenced to death.
But, there he fell in love with the jailer's daughter, and before his execution on February 14, he wrote her a love letter inscribed "from your Valentine." Therefore every year, on February 14, Valentine's day, also known as St Valentine's Day or the Feast of Saint Valentine, is celebrated.
