Provinces of Mongolia
The aimags (Mongolian Аймаг, tribe, tribal group ) form the top level of the regional Administrative divisions of Mongolia. An aimag is subdivided into several Sum. The capital Ulaanbaatar is managed separately.
Towards the end of the Qing dynasty of the Manchus in China, the then territory of Outer Mongolia was divided into the Khanate Khovd, Jassaktu, Sain Noin, Tushetu, and Tsetsen. After the Mongolian Declaration of Independence of 1921, the provinces Alxa, Ordos, Shilin Gol, and Jirim remained in China, and Tuva was an independent republic Urianhai. The existing administrative division was first obtained within the new Mongolian People's Republic.
After the end of the Russo -Japanese War of 1941 was an administrative reorganization, from which emerged the aimags Archangai, Choibalsan, Dorno Gobi, Dsawchan, Khentii, Khovd, Chöwsgöl, Ömnö Gobi, Öwörchangai, Töw and Uvs. 1954 was a long strip of the southern Gobi back to China. The division in the remaining Mongolia has been refined, and the aimags Bajanchongor, Bajan Ölgii, Bulgan, Dand - Gobi Gobi - Altai and Sükhbaatar emerged. The Selenge Aimag was split two years later by Töw Aimag.
In 1963, the Choibalsan Aimag the new name Dornod aimag and the capital of Ulan Bator ( Ulaanbaatar today ) was spun off as a separate administrative unit from the Töw Aimag. The same status was granted to the newly founded industrial cities Darkhan (1961 in Selenge Aimag ) and Erdenet (1975 in Bulgan aimag ). 1994, two Sum of Bulgan aimag were spun off, and charged with Erdenet together to Orkhon Aimag, just emerged from four sum of Selenge aimag and Darkhan Darkhan - Uul aimag of. The Gobi Sümber Aimag was split off in 1996 by Dorno Gobi aimag.
