A medievalist explains how romantic love emerged as a cultural concept

Many long-form stories written in English were originally considered "romances," a term derived from the Old French word for "the speech of the people." But changes in medieval culture, triggered by a number of 12th-century church reforms, led to a new interest in what we now consider romantic love, including a new view of marriage as a pursuit of love rather than a transaction. Those new perspectives were then reflected in the period's popular stories, including stories in Chaucer's "Canterbury Tales."

Read a 19th-century guide to writing a Valentine's Day card

Thomas Richardson's "London Fashionable Gentleman's Valentine Writer" offers readers romantic messages they can send to the objects of their eyes—along with some chippy kiss-offs for unwanted suitors. It might be sincere, or it might be satire. Either way, it's an entertaining read. (Some readers may experience a paywall.)

'Roses are red, violets are blue' has a long, twisting history

The earliest known use of the phrase, a stock romance form used in greeting cards, is in Edmund Spenser's "The Faery Queen" from 1590 (excerpt below). By 1785, Joseph Ritson updated the verse and connected it to Valentine's Day, creating a cliché that's still used today.

The dark origins of Valentine's Day.

The holiday began as a feast to celebrate the decapitation of a third-century Christian martyr, or perhaps two. So how did it become all about love?

Valentine's Day's namesake is unclear

Valentine, which means "powerful" or "worthy," was a popular name in the Roman Empire. Considering that, it's no surprise that there's more than one St. Valentine. In fact, three different men named Valentine were martyred on February 14, and none of them, despite some unproven legends, were ever associated with love or romance.

Some believe Valentine's Day evolved from the Roman holiday Lupercalia

The festival, which took place in mid-February, featured Roman priests sacrificing a goat and using its hide to lightly slap women and the land, believing it would bring fertility. Some believe that the Catholic Church repurposed the pagan holiday as a Christian one by attaching it to a saint, but scholars are not certain that this is true.

An early literary mention of a New Year's kiss dates to the 14th century

The medieval poem “Sir Gawain and the Green Knight” includes a description of a New Year’s party where women are planning on giving “New Year’s gifts” to men. Scholars say it’s implied that the “gifts” are kisses.

19th-century 'vinegar valentines' sometimes mocked recipients

In Victorian England, cards were sent to paramours and crushes, but they were also sometimes sent to people the sender disliked and would belittle them for their occupations or appearances. It was also expected that anyone who received a Valentine's Day card would send one in return, so there was a subgenre of responses, including rejections for unwanted suitors.

Check out Valentine's Day traditions from around the world

Valentine's Day is a holiday all about romance, but the way that's expressed differs depending on where the celebration takes place. This list breaks down some interesting takes on the holiday from across the globe, including mass weddings in the Philippines and Japan's gender-specific chocolate exchanges.

The petty ancient Roman poet Gaius Valerius Catullus

Classics with a capital "C" probably doesn't bring to mind erotically charged diss poetry. Gaius Valerius Catullus would like to change that. Instead of mythical epics, Catullus wrote poetry about his personal life as part of the 1st century BCE's "new wave" of Roman poets embracing the lyrical and everyday. The focus of his poetic work ranges from serenades to spiteful insults.

Hallmark helped popularize (and commercialize) the holiday in the early 20th century, largely through its greeting cards. This digital collection includes cards from the 1910s through the 2000s, allowing you to see how the holiday—and our popular understanding of romance—has evolved. Below is a card from the 1930s.

Reforms reducing postage rates helped popularize Valentine's Day cards

In 1845, Congress voted to slash postage rates, paving the way for larger swaths of the American public to send and receive mail. This convenience was capitalized on by paper and stationery sellers who sought to profit from the holiday. Esther Howland's New England Valentine Company was the first major commercial producer of valentines in the US, but Hallmark followed a few decades later.

In the 20th century, Valentine's Day became more commercialized

Historian Elizabeth Nelson notes that companies sought "to turn holidays into opportunities for selling things from candy to flowers to magazine advertisements" in the 1900s. Hallmark, founded in 1911, pushed the holiday toward elementary students, who aimed to collect cards from as many classmates as possible.

The best Valentine's Day-themed horror movies

It may seem like an odd combination—a holiday centered on love and a film genre dedicated to fright—but the hyperspecific subgenre thrives on the apparent juxtaposition, along with some campy send-ups of an overly commercialized holiday.

The average person celebrating Valentine's Day spends $189

That might include dinner, flowers, or something even more romantic. The most popular gift is candy, with 56% of people celebrating the holiday by purchasing sweets. That's about $2.5B in sales.

Esther Howland built a Valentine's Day card empire in 19th-century New England

In 1849, Howland launched her card business, the New England Valentine Company, in her home, staffing an assembly line with her friends, who'd piece together the intricate valentines. The cards were elaborately decorated, with silk, lace, and romantic verse. Howland's annual sales eventually grew to $100K and helped popularize the holiday in the US.

'Romeo and Juliet' was based on a preexisting narrative poem

Arthur Brooke's "The Tragical History of Romeus and Juliet" was first published in 1562 and shares many details with Shakespeare's "Romeo and Juliet." Shakespeare wasn't alone in his borrowing; Brooke's poem was based on other earlier Italian stories. None of this writing was considered fan fiction—copyright law didn't exist, and stories were regularly cribbed from preexisting sources.

Sir Thomas Overbury's poem "A Wife" inspired its subject to poison him

Overbury wrote the critical poem to suggest that the ex-wife of his friend Robert Carr, Frances Howard, had failed in her marital duties. Its contents enraged her, leading her to craft a conspiracy that left Overbury dead from poisoning.

Romanticism was an 18th and 19th century creative movement

The movement emphasized the beauty of nature and human feeling.

Shakespeare played a major role in the history of the sonnet

At one point in the 1602 play, the character Falstaff calls for a quart of wine, asking for toast to be placed in it, as was customary at the time.

Love is a more recent part of marriage

Love matches are incredibly late to the marriage game. For most of our history, marriage has been about alliance, wealth, property, power, and, as an occasional afterthought, the couple liking each other. All that changed when Enlightenment thinkers were inspired in their pursuit of personal happiness, including in their choice of mate.

In addition to his plays, Shakespeare wrote nearly 200 poems

Beyond his famous plays, Shakespeare penned 154 sonnets, including the well-known romantic ode “Shall I compare thee to a summer’s day?” He also wrote two long poems as well as several minor pieces.

O'Connor raised 40 peacocks, which became symbols for her fiction

O'Connor was drawn to peacocks because of their dichotomy—people were drawn to the beauty of their feathers but turned off by the ugliness of their behavior. It was an apt symbol for her fiction and the birds featured prominently on several of her books' covers.

The Easter Bunny traces to German folklore, not ancient paganism

The rabbit's connection to Easter is well-documented from the 17th century onward, but the deeper origins remain unclear (particularly why a mammal that does not lay eggs became the egg-loving holiday's secular mascot). German immigrants brought the tradition in the 1700s, introducing the mythical egg-laying rabbit known as the "Osterhase," whose nests became the Easter basket.

How Shakespeare changed the sonnet

A sonnet is a rigid poetic form from the Renaissance, featuring 14 lines, a consistent meter (or beat) and rhyme scheme, and a noticeable thematic shift known as a "volta."
