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

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.

Mardi Gras blends pagan celebrations with Christian traditions

The holiday has its roots in pagan celebrations, like ancient Rome's Saturnalian and Lupercalian festivals, which celebrated spring and fertility. Rather than abandoning these traditions, Catholic leaders in Rome incorporated their spirit into a celebration that would expel citizens' debauchery in preparation for the sacrifices they'd endure during the Lenten season. Around the world, this holiday season is called Carnival, though the New Orleans version is usually called Mardi Gras.

Valentine's Day is a holiday all about romance, but the way that's expressed differs depending on where the celebration takes place.

Poet Geoffrey Chaucer inspired the modern, romantic version of Valentine's Day

In the 1380s, the "Canterbury Tales" author wrote "The Parliament of Fowls," a 700-line poem about birds that choose their mates on St. Valentine's Day. The poem argued that romantic love—for fowls and humans alike—was an ideal, and linked the holiday with that sentiment.

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.

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.

Advertisers emphasized Cupid's childlike qualities to appeal to a younger demographic

Cupid is the Roman god of desire, and was often depicted in ancient mythology as both childlike and violent. In the 1800s, however, American advertisers eager to appeal to a younger demographic leaned into the less threatening versioning, portraying him as a cherubic child.

Halloween originated with the Celtic festival of Samhain

Halloween, a holiday primarily popular in the US and Canada, originated 2,000 years ago with the Celtic people.

The Quartodeciman controversy debated what day to celebrate Easter in the early church

Asian churches marked Easter on the 14th day of the Hebrew month of Nisan (roughly March-April), while Roman churches insisted on Sunday. Polycarp of Smyrna, an associate of the Apostle John (who tradition says wrote one of the four Gospels) traveled to Rome to advocate for the 14th of Nisan. The Nicene Council decided that celebrating on a Sunday would ensure Christian unity and distinguish the observance from Jewish passover.

Why Christians eat fish on Fridays during Lent

The rule isn't actually to eat fish—it's to abstain from eating warm-blooded animals on Fridays, the day of the crucifixion. Fish filled the gap because it was cheap, plentiful, and theologically convenient. As it happens, the medieval Catholic calendar's proliferation of meatless days became one of the drivers of the global fishing industry.

The evolution of the Olympics from ancient Greece to the modern world

The Olympic Games have evolved from a sacred footrace in 776 BCE honoring Zeus to a global celebration of athletic excellence and unity. Ancient Greek city-states set aside their conflicts under a sacred truce for events like wrestling and chariot racing. Though the Games ended in 393 CE, Pierre de Coubertin revived them in 1896, adding modern elements like the torch relay and the inclusion of women. Watch 1440's breakdown of the historic event here.
