The necktie was invented in the 17th century during the Thirty Years' War (1618-1648). Croatian soldiers hired by King Louis XIII of France wore a piece of cloth around their necks as part of their uniform, which caught the king's attention and became a fashion among the French elite. The item was called a cravat, derived from the French word for Croatian ("la Croate"). This style spread across Europe and evolved into the modern necktie over the centuries. The modern necktie's current form was shaped significantly in the 1920s by Jesse Langsdorf, a tie maker from New York who patented a new way to cut and sew fabric for ties.
