Valentine’s Day has roots in ancient Rome, early Christianity, and later medieval poetry, and only gradually became the romantic holiday we know today.

From Roman festival to saint’s day

Many historians link Valentine’s Day to Lupercalia , a mid‑February Roman festival that celebrated spring, fertility, and the pairing of men and women by lottery. In the late 5th century, Pope Gelasius I banned Lupercalia and is sometimes credited with replacing it with a Christian feast of St. Valentine on February 14, though the exact connection is unclear.

The day is named for one (or more) Christian martyrs called Valentine, but the historical record is blurry. Over time, legends grew around a priest who secretly married couples in defiance of a ban and who supposedly signed a farewell note “from your Valentine” before his execution, a story often dated to around 270 CE.

When it became about romance

The association of Valentine’s Day with romantic love came centuries later, especially in medieval Europe. By the 14th century, the English poet Geoffrey Chaucer was linking St. Valentine’s Day with love and the mating of birds in works like “The Parliament of Fowls,” helping to frame February 14 as a day for lovers.

In 15th‑century France and England, nobles began exchanging romantic messages on this date. One famous early example is a poem written in 1415 by Charles, Duke of Orléans, to his wife while he was imprisoned in the Tower of London, often cited as one of the first known written Valentines.

Cards, Cupid, and Victorian commercialization

By the 1500s, formal Valentine messages were circulating, and commercially printed Valentine cards appeared by the late 1700s in Europe. In 18th‑century England, the day became an occasion for couples to present flowers, sweets, and handwritten “valentines,” establishing many of the traditions we still recognize.

The 19th century brought mass production. In the United States, the first commercial Valentines were printed in the mid‑1800s, and Esther A. Howland—often called the “Mother of the American Valentine”—built a successful business creating elaborate lace and paper cards that helped popularize the practice nationwide.

Modern symbols and global spread

Today’s Valentine’s Day blends these older strands of folklore, religion, and commerce. Common symbols include hearts, doves, and Cupid, the Roman god of love, along with red roses, which are widely seen as emblems of beauty and passion.

The holiday has also moved beyond strictly romantic love. In many places people give cards, flowers, or small gifts to friends, family members, and classmates, and the date has become a major event for retailers, restaurants, and online culture each February.
