The Constitution of Mongolia adopted in 1992 states that The President of Mongolia is the Head of State and embodiment of the unity of the Mongolian people.
Mongolia declared its independence from the Qing dynasty in 1911, under the Bogd Khan (the 8th Jebtsundamba Khutuktu). From 1911 to 1924, the head of state of Mongolia was nominally the Bogd Khan. During 1924 to 1992, during the Mongolian People's Republic, the official title of the head of state underwent several changes, including Chairman of the State Great Khural, Chairmen of the Presidium of the State Little Khural, Chairmen of the Presidium of the State Great Khural, and finally, Chairmen of the Presidium of the People's Great Khural.
