History: 

The area around Nakhon Ratchasima was already an important centre in the times of the Khmer empire in the 11th century, as can be seen by the temple ruins in Phimai historical park. Nakhon Ratchasima Province is one of the provinces where there is still a sizable northern Khmer population. 

Nakhon Ratchasima has long been the most important political and economic centre in the northeastern region. In the late-19th century, the railroad reached Khorat and it became the junction of two main rail lines in the northeastern, Isan, region. In 1933 it was the stronghold of the royalist troops in the Boworadej Revolt, as they fought against the new ostensibly democratic government in Bangkok. In the 1950s, the Korat Royal Thai Air Force Base was built in Nakhon Ratchasima; from 1961 until 26 February 1976, this facility was also used as a base by the United States Air Force.
