Descent from Genghis Khan (
Altan urag, meaning "Golden lineage";
Kazakh : Töre), generally called
Genghisids, is traceable primarily in
Central Asia; Mongolia,
Inner Mongolia in China, Siberia and Koreas. His four sons and other immediate descendants are famous by names and by deeds. Later Asian potentates attempted to claim descent from the
House of Borjigin even on flimsy grounds, such as was considered Mongol matrilineal descent. In the 14th century, valid sources (heavily dependent on
Rashid al-Din and other
Muslim historians) all but dried up. With the recent popularity of
genealogical DNA testing, a wider circle of people started to claim descent from Genghis Khan.
