when did valentine's day start

Valentine’s Day gradually developed over many centuries, rather than “starting” on one exact date, but there are a few key milestones that people usually mean when they ask when it began.

Super short answer

• As a Christian feast for St. Valentine: by the late 400s, when Pope Gelasius I placed St. Valentine’s Day on February 14.

• As a romantic, love-focused day: late 1300s–1400s, when writers like Geoffrey Chaucer linked February 14 with romantic love and bird mating season.

• As a modern card-and-gifts holiday: from the 1700s in Europe, then especially the mid‑1800s with mass‑produced valentines and heart‑shaped chocolate boxes.

Where it really began

Historians point to a mix of ancient Roman and early Christian roots rather than a single “start day.”

• In ancient Rome, a mid‑February festival called Lupercalia celebrated fertility and the coming of spring, and some scholars think Valentine’s customs may echo parts of it.

• In the 5th century, Pope Gelasius I officially established February 14 as St. Valentine’s Day and ended the older festival, turning the date into a Christian feast day instead.

• At this stage, it was a religious observance, not yet a day when people exchanged love notes or gifts.

So in one sense, Valentine’s Day “started” as a church feast in the 400s , but it still wasn’t a romance holiday.

How it became about romance

The romantic side shows up much later, in medieval Europe.

• In the Middle Ages, people in England and France believed that birds began their mating season around February 14, which helped link that date with pairing and love.

• The poet Geoffrey Chaucer is often credited as the first person to clearly connect St. Valentine’s Day with romantic love, in a 14th‑century poem called “The Parliament of Fowls.”

• By the early 1400s, we see the first known “Valentine” love letter: Charles, Duke of Orléans, wrote a poem to his wife while imprisoned in the Tower of London in 1415.

From then on, February 14 slowly gained a reputation as a day for lovers, especially in parts of Europe.

When cards and gifts really took off

The familiar, commercial Valentine’s Day is much more recent.

• Handwritten valentines were common by the 1700s in Britain; people exchanged short notes and simple tokens.

• By the late 1700s, commercially printed cards appeared, and in the United States, the first commercial valentines were produced in the mid‑1800s.

• In 1868, Richard Cadbury introduced one of the first heart‑shaped boxes of chocolates for Valentine’s Day, helping cement chocolate as a standard gift.

• American entrepreneur Esther Howland popularized elaborate, mass‑produced valentines using an assembly‑line approach, making decorative cards widely affordable.

By this stage, Valentine’s Day looked much closer to what people recognize now: cards, candy, flowers, and romantic gestures centered on February 14.

Today’s angle and “trending” context

Modern Valentine’s Day is both a huge commercial event and a flexible celebration that goes beyond couples.

• It’s now common to celebrate friends and family as well as romantic partners, and some people even use it as a day to focus on self‑care and self‑love.

• Media and brands regularly highlight alternative celebrations—like “Galentine’s” gatherings, anti‑Valentine themes, or inclusive events that frame love as something you show all year.

• Despite the changing social trends, the core symbols—hearts, Cupid, flowers (especially red roses), and sweets—still trace back to the 18th–19th‑century evolution of the holiday.

Quick timeline recap

1. 3rd century: Stories emerge of a Christian priest named Valentine in Rome, later associated with secret marriages and martyrdom (though details are partly legendary).

2. 5th century: Pope Gelasius I designates February 14 as St. Valentine’s Day, replacing older Roman festivals.

3. 14th century: Geoffrey Chaucer links St. Valentine’s Day with romantic love and bird mating season.

4. Early 1400s: First known Valentine love letter written by Charles, Duke of Orléans.

5. 1500s–1700s: Exchanging valentines (messages of love) becomes more common in Europe.

6. Late 1700s–mid‑1800s: Printed valentines and mass‑produced cards spread in Britain and the U.S.

7. Late 1800s: Heart‑shaped chocolate boxes and commercially produced cards help create the modern Valentine’s Day.

TL;DR: Valentine’s Day as a named day started as a Christian feast in the 400s, but Valentine’s Day as a romantic, gift‑giving holiday really “started” in late medieval Europe and became the modern celebration only in the 1700s–1800s.
