History
The history of the city of Chaiyaphum dates back to the Khmer Empire in the 12th century, when it was a small city on the route from Angkor to Prasat Singh (Kanchanaburi province).
In 1817 the area was settled by Lao people led by Nai Lae, an official of King Anouvong of Vientiane, which was a tributary state of the Thai monarch. They settled in Baan Nam Khun Nong E Chan in Nakhon Ratchasima province, but soon abandoned it in favor of Ban Luang (today's city of Chaiyaphum). In 1826 Anouvong rebelled against the Thai King Rama III, seeking to gain complete independence. Nai Lae, by then made a chao praya by the Thai monarch, supported the Siamese troops. Chao Phaya Lae was killed defending his city against Anouvong's army, but Anouvong was defeated by Thai forces weeks later and Anouvong taken in chains to Bangkok. King Rama III remembered Chao Phaya Lae for his loyalty and awarded him the title Phraya Phakdi Chumpon. He is still a local hero and his statue has become a symbol of the province.
