The Ruby Garland is a genealogy of the Tibetan clans Barchung and Ju, descended from Genghis Khan. It might be the only Tibetan historical document that holds a clear account of Buddhism's existence in Mongolia during the Ming Dynasty (1368–1644). Parallel historical narratives can be found in the official historical records of the Ming Dynasty, the Ming Shi (明史).
