If you're wearing a necktie to work today, you can thank (or blame) the Croatians for this stylish invention. The necktie's predecessor, a short knotted garment called the cravat, is a source of pride in this Western Balkan nation—so much so that they celebrate Cravat Day each year on October 18.
It's unclear when exactly the necktie was invented, but Croatian soldiers wore red cravats as part of their uniform during the Thirty Years' War (1618-1648). According to The Atlantic, Croatian mercenaries carried it to Western Europe that same century, and the French borrowed the idea and dubbed it the cravate. It became even more stylish when Louis XIV of France started wearing a lace cravat in 1646 at the tender age of 7, according to The Dubrovnik Times. The English eventually helped spread the accessory around the world, and it morphed into the elongated form we're most familiar with today.
In 1997, a nonprofit organization called the Academia Cravatica was founded to promote the cravat as a symbol of Croatian ingenuity. "By spreading the truth about the cravat, we improve Croatia's image in the international public," the organization states. "The fact that Croats invented the Cravat makes us proud to be Croats." (According to Time Out, Croatia also invented the first MP3 player, the zeppelin, the parachute, and fingerprint identification.)
The cravat is also tied up with national identity. The words Croat and cravat are etymologically linked, and were once different spellings of the same word. One sample sentence by David Hume in 1752 reads, "The troops are filled with Cravates and Tartars, Hussars, and Cossacs."
The holiday isn't normally a big to-do, but the county's capital city, Zagreb, occasionally gets pretty festive. In 2003, when the holiday first debuted in Croatia, the Academia Cravatica wrapped an oversized red necktie around Pula Arena, a Roman amphitheater. It took two years to prepare and five days to install—and at 2650 feet long, it ended up being the largest necktie in the world, as recognized by Guinness World Records.
Cravat Day was formally declared a holiday by Croatian Parliament in 2008, and it's been a hallmark of Croatian culture ever since. A few events were planned in Zagreb today, including a march featuring the "city's famous Cravat Regiment." So if you happen to be in the Croatian capital, now you know why more than 50 historic statues are looking dapper in their red cravats.
