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.

In order to diminish the predominant influence of the Tüsheet Khans in Khalkha, in 1725, the Yongzheng Emperor of Qing created Sain Noyon Aimag, carved out of 19 khoshuu (sub-districts) in western Tüsheet Khan Aimag. During Qing dynasty, the title of Sain Noyon rulers was khoshoi chin van (хошой чин ван), lower than khan. However, their influence was no less than that of three Khalka khans. 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.

After Mongolian independence from the Qing China in 1911, the ruler of Sain Noyon was given the title of "Khan" by the order of Bogd Khan, since then, the aimag was renamed "Sain Noyon Khan". In 1923, following the Mongolian Revolution of 1921, the Sain Noyon Khan aimag was renamed Tsetserleg Mandal uulyn aimag (Цэцэрлэг Мандал уулын аймаг), which named after Tsetserleg. In 1930, the four aimags were divided into the present day 21 smaller aimags, which were subdivided into sums.
