Tuman, Prince of Yangi

Tuman was a Mongol prince of the House of Ögedei, descended from the khan's youngest son Melik, whose family roamed the Irtysh valley and had followed Kaidu. After Kaidu's death and the collapse of his ulus, the line submitted to the Yuan.

In 1308 Tuman presented the court with the jade seal of Ögedei long kept by his family, and the Yuan emperor invested him as Prince of Yangi with a golden seal. His son Küčün inherited the title.
