Bayid

The Bayad (Mongol: Баяд/Bayad, lit. "the Riches") is the third largest subgroup of Mongol people in modern Mongolia and they are a tribe in Four Oirats. Baya'ud were a prominent clan within the Mongol Empire. Baya'ud can be found in both Mongolic and Turkic peoples. Within Mongols, the clan is spread through Khalkha, Inner Mongolians, Buryats and Oirats.

Only the latter appears to be connected to the modern Bayad people of western Mongolia. A common clan name does not mean common origin, the clan names Bayad and Baya’ud are differentiated. The Bayads appear to be Siberian peoples subjugated by the Dorbet tribe of the Oirats. Like all the Oirat tribes, the Bayads were not a consanguineal unit but a political-ethnographic one, formed of at least 40 different yasu, or patrilineages, of the most diverse origins.
