Noyan

noyad), or Toyon, was a Central Asian title of authority which was used to refer to civil-military leaders of noble ancestry in the Central Asian Khanates with origins in Noyon, which was used as a title of authority in the Chagatai Khanate of the Mongol Empire.

In modern times, Noyan is used as a given name or surname in Asia meaning "the lord", "the prince", "the protector", "the commander-in-chief".

[2] Under Genghis Khan the term "Noyon" applied to leaders of Tumens and Mingghans, social-military units of 10,000 and 1,000 households respectively, each of them with one recruitable soldier.

In times of peace the Noyons ruled as lords over these households and governed the use of the pasture lands.

They were sometimes called emir or bey in the Ulus of Jochi, the Ilkhanate and the Chagatai Khanate while historical records of the Yuan dynasty of China gave the equivalent as guanren (官人).
