Sain Noyon Khan

The first ruler of Sain Noyon tribe Tümenkhen was a grand son of Gersenji Khongtaiji.

He was awarded the title "Sain Noyon" by the 4th Dalai Lama because of his great contribution to the Tibetan Buddhism in Mongolia.

[1][2] During Qing dynasty, the title of Sain Noyon rulers was khoshoi chin van (хошой чин ван), lower than khan.

Since 1728, each aimag was governed by aimag congress chigulgan (чуулган) comprising the lords of the khoshuns; the chigulgan daruga (чуулган дарга - official presiding the congress) was appointed from the khoshun lords by the Qing government.

the congress of Sain Noyon aimag was called the "Tsetserlegiin chuulgan" (Цэцэрлэгийн чуулган, 齊齊爾里克盟), which was held every three years in Tsetserleg.
