History

The area around Korat 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 the Phimai historical park. The new walled- city with moat, Nakhon Ratchasima, was built in the seventeenth century by order of the Ayutthaya King, Narai, as the easternmost command post, guarding the Kingdom's border, and supervise its Lao and Cambodian vassals.

It took over this duty during the Bangkok Period, and became the stronghold against the Lao incursion in the nineteenth century, although it was first seized. Even from the creation of Siam as a nation at the end of nineteenth century, Nakhon Ratchasima continued to be the most important political and economic centre in the northeastern region.

In the late nineteenth century, the railroad first arrived and Korat became the junction of two main rail lines in the Northeastern, Isan, region. In 1933 it was the stronghold of the royalist troops, leading the abortive attempt, known as Boworadej Revolt, rebelling against new democratic government in Bangkok. In the seventies, the city was again the site of US bases operating in the Vietnam War.

Nakhon Ratchasima, Issan, often called Korat
