While it is widely associated with romantic partners, the occasion has gradually grown to include friends, family members and even classmates, with cards, flowers and thoughtful gestures exchanged to show appreciation.

From ancient traditions to a Christian feast

The roots of Valentine's Day are layered and debated. Some historians link it to Lupercalia, an ancient Roman festival held in mid-February that was connected to fertility and the coming of spring. However, many scholars argue there is limited evidence directly tying the modern celebration to that pagan event.

A more widely accepted account connects the day to Saint Valentine, a Christian priest who lived during the reign of Roman Emperor Claudius II. At the time, Claudius reportedly banned marriages for Roman soldiers, believing unmarried men made better warriors. According to tradition, Valentine defied this order and secretly performed Christian wedding ceremonies for soldiers.

His actions were eventually discovered, leading to his arrest and imprisonment. Legend says that while in jail, Valentine cared for fellow prisoners and befriended the jailer's blind daughter, whom he is said to have healed. Before his execution on February 14, around the year 270, he is believed to have sent her a note signed "From your Valentine" - a phrase that endures to this day.

The Catholic Church later designated February 14 as the feast day of Saint Valentine, cementing the date's religious significance.

When romance took centre stage

Valentine's Day became closely associated with romantic love during the Middle Ages. In the 14th and 15th centuries, writers such as Geoffrey Chaucer described February as a season when birds chose their mates, reinforcing the idea of the day as a celebration of courtship.

By the 16th and 17th centuries, people in parts of Europe began exchanging handwritten notes and verses. The practice evolved further in the 18th and 19th centuries, when printed greeting cards gained popularity, particularly in Britain and the United States. Over time, flowers, chocolates and symbolic gifts became customary.

A global celebration of affection

Today, Valentine's Day is observed in countries including the United States, the United Kingdom, Canada, Australia and many parts of Europe, Asia and Latin America. While customs vary, the core theme remains the same: expressing care and gratitude.

In some places, schoolchildren exchange cards with classmates. Elsewhere, couples mark the occasion with special meals, poetry or gifts. Though commercialisation has become a visible part of the celebration, many still view the day as a meaningful opportunity to recognise love in all its forms.
