Romance, love, flowers and candy hearts, that’s what Valentine’s day is all about, right? Not exactly – from its bloody origins to chocolaty modern day traditions, here are 21 interesting facts you probably didn’t know about Valentine’s Day.
1. Valentine’s Day started as a form of rebellion: The most popular theory about Valentine’s Day origin is that Emperor Claudius II didn’t want Roman men to marry during wartime. Saint Valentine went against his wishes and performed secret weddings for which he was jailed and eventually executed — but not before he wrote a love note to the jailer’s daughter… signing it, “From your Valentine.”
2. Chaucer may have invented Valentine’s Day: The medieval English poet Geoffrey Chaucer often took liberties with history, placing his poetic characters into fictitious historical contexts that he represented as real. No record exists of romantic celebrations on Valentine’s Day prior to a poem Chaucer wrote around 1375. In his work “Parliament of Foules,” he links a tradition of courtly love with the celebration of St. Valentine’s feast day–an association that didn’t exist until after his poem received widespread attention. The poem refers to February 14 as the day birds (and humans) come together to find a mate. When Chaucer wrote, “For this was sent on Seynt Valentyne’s day / Whan every foul cometh ther to chese his make,” he may have invented the holiday we know today.

3. Its first official celebration was to honor women’s rights : “The High Court of Love” was established in Paris, France, on this day in 1400 and is the first known official celebration of Saint Valentine’s Day. Composed of 30 women, it dealt with love contracts, violence against women, and betrayals.

7. A medieval twist on PDA : The saying “wearing your heart on your sleeve” is from the Middle Ages. Boys at this time would draw names of girls to see who would be their “Valentine” and then wear the name pinned on their sleeve for a week.
8. An Architectural inspiration : Madame Royale, daughter of Henry the IV of France, loved Valentine’s Day so much that she named her palace “The Valentine.”

9. Henry VIII decided when Valentine’s Day should be celebrated : Marrying a total of six women throughout his lifetime, there’s no denying Henry VIII was a BIG fan of women and probably a rather big romance – but did you know he is responsible for when we actually celebrate Valentine’s Day? Back in 1537, King Henry VIII declared by Royal Charter that Valentine’s Day would be a public holiday chose 14 February as the official day of celebration.
