“The Family Chart of Hereditary Lords of the Khalkha Mongols, the House of Genghis Khan” is a genealogy chart of 980 Genghisids that runs for thirty generations covering almost 700 years of Mongolian history and was compiled around 1832-1862. The chart is in the shape of multiple layers of a circular diagram reminiscent of the sun’s rays written with a brush in black and red ink on a coated canvas measuring 85 by 88 centimetres. The core circle starts with Genghis Khan followed by his youngest son Tolui Noyan, his grandson Kublai Khan, his great-grandson Crown Prince Chinkin, going on to include other emperors and princes of the Yuan dynasty and North Yuan, khans and princes of Khalkha Mongols. The Family Chart is significant because it is dedicated to the members of the famous Golden Clan, who played a significant role in enhancing cross-cultural exchange primarily in Central and East Asia through their cultural and trade-related policies. This document is one of only three remaining, oldest and most well-preserved authentic sources for studying the genealogy of Genghisids, because other related documents were destroyed during the Great Purge of the 1930s.
