The region of Khevsureti in Georgia is the historic home of a group of Kartvelian highlanders known as Khevsurs. As Khevsureti’s popularity as a mountain tourist destination has grown, so too has the popularity of an old story that asserts the Khevsurs are the descendants of a lost band of Crusaders. For 200 years, this meme has manifested itself in books about the region, newspaper articles, the work of a few scholars, and now much Internet discussion. The growing collection of cases has created the illusion of an unconsolidated quantity of evidence and many commentators have since taken the story to be a credible theory or actual legend. A systematic deconstruction and analysis of this story shows how this set of details initially formed, grew, and spread based on a few unreliable accounts in circulation beginning in the early 19th century. This article offers a case study of how such memes form and propagate; it provides an additional example of a Western tendency to romanticize and project elements of their own ethnicities into the Caucasus; and it examines this false history in terms of cultural appropriation and the relationship between ethnicity and narrative, adding to the literature on invented histories and pseudoarchaeology. Finally, this careful deconstruction and repudiation will help remove this story from serious discussions of cultural heritage in Khevsureti and show how historical memes and popular examples of pseudoarcheology spread and capture imaginations.
