It was one of four Khalka khanates that emerged from remnants of the Mongol Empire after the death of Dayan Khan's son Gersenji Khongtaiji in 1549.
The first ruler of Zasagt tribe was Gersenji's eldest son, Ashikhai. At the beginning of the 17th century, Ashihai's grandson Laihur was awarded the title of "khan" by Abtai Sain Khan. Laihur was murdered in 1587. His son Subadai succeeded and crowned himself the "Bogd Zasagt Khan". Later, Norob, Vanchig, and Tsengüün succeeded to the title of khan.
In 1687, Shar, the Zasagt Khan, was defeated and killed by Tüsheet Khan Chakhundorj. His younger brother Tsevenjab succeeded as the new khan, however, Khalka was invaded by Dzungar Mongolian forces under Galdan Boshugtu Khan in the next year, Tsevenjab had to flee to Ulanqab where he pledged fealty to the Kangxi Emperor of the Qing China. On 3 June 1691,<ref>[https://www.degruyter.com/document/doi/10.7312/wu--20616-006/pdf Chapter Three ASSEMBLIES, From the book Common Ground]</ref> Tsevenjab attended the Dolonnuur Assembly together with Tüsheet Khan, Sechen Khan and more than 500 noyans and taijis. Since then, the Khalkha Mongols in Outer Mongolia submitted to the Qing dynasty.<ref>{{cite web | title =Долоннуурын чуулган |url = https://mongoltoli.mn/history/h/876 |website=Монголын түүх|language=mn}}</ref> The three khanates, Zasagt Khan, Sechen Khan and Tüsheet Khan, became three provincial subdivisions or ''aimags'' of Qing China. In the next year, Khalka was divided into three ''zam''s ({{lang|mn|зам}}), the area of Zasagt Khan aimag was named "Khalka Right Zam" ({{langx|mn|Халхын өрнө зам}}, {{zh|t=喀爾喀西路}}).<ref name="Засагт хан">{{cite web | title =Засагт хан аймаг |url = https://mongoltoli.mn/history/h/85 |website=Монголын түүх|language=mn}}</ref> In 1725, Qing China created a fourth ''aimag'', Sain Noyon.<ref name=":0">{{Cite book|title=Historical Dictionary of Mongolia|last=Sanders|first=Alan A.

In 1923, following the Mongolian Revolution of 1921, the Zasagt Khan aimag was renamed '''Khan Tashir Uulyn aimag''' ({{lang|mn|Хан Тайшир уулын аймаг}}),<ref>{{cite book | url = https://books.google.com/books?id=fMfbAgAAQBAJ&dq=Khan+Khentii+Uulyn+aimag&pg=PA169 | title = Historical Atlas of Northeast Asia, 1590-2010: Korea, Manchuria, Mongolia, Eastern Siberia | first1=Narangoa |last1=Li|first2= Robert |last2=Cribb |publisher = Columbia University Press |year = 2014 |isbn=9780231537162 | page = 169}}</ref> which named after the {{ill|Khan Taishir Ridge|mn|Хан тайширын нуруу}}.<ref name="Засагт хан"/> In 1930, the four ''aimag''s were divided into the present day 21 smaller ''aimag''s, which were subdivided into ''sum''s.
