In 1817 the area was settled byLao people led by Nai Lae, an official of KingAnouvong ofVientiane, 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 KingRama III, seeking to gain complete independence. Nai Lae, by then made achao 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 toBangkok. 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.
