The National Museum of Mongolia [Mongolian:Монголын үндэсний түүхийн музей; formerly the National Museum of Mongolian History] is one of the national museums of Mongolia located in the capital Ulan Bator. The National Museum of Mongolia is a cultural, scientific, and educational organization, which is responsible for the collection, conservation and interpretation of the objects under its curation.
The first museum in Mongolia, which was called the Mongolian National Museum (now the Mongolian Natural History Museum), was established in 1924 and became the basis for other museums, including the National Museum of Mongolian History. Russian scholars, such as P. K. Kozlov, V. I. Lisovskii, A. D. Simukov, and the American researcher R. C. Andrews contributed to the museum's early collections and exhibits.
The modern National Museum of Mongolian History was established after the merger of the historical, archaeological and ethnographical departments of the State Central Museum and the Museum of the Revolution in 1991. It is now located in a facility built for the Museum of the Revolution, which was founded in 1971. The National Museum of Mongolia is currently recognized as one of the leading museums in Mongolia. The significant responsibility for preserving Mongolian cultural heritage therefore lies with the museum. It is also responsible for developing museological guidelines for museums in the nation.
