The male given name Tristan is of French origin, deriving from the ancient Breton word "drust," meaning "noise" or "uproar." It gained popularity through the medieval legend of Tristan and Isolde, in which Tristan, a Cornish knight, aided his uncle King Mark to wed Irish princess Isolde. However, after drinking a love potion intended for the king, Tristan fell deeply in love with Isolde himself, leading to their tragic yet enduring love story that continues to captivate audiences today.
