n 1759 the White Elephant of King Ekkathat escaped from Ayutthaya to the forest in Khwaeng Mueang Phimai area. Chiang Kha (เชียงฆะ), leader of Ban Khok Atcha and his groups volunteered to catch the elephant and succeed. King Ekkathat promoted him to be Phra Sangkhaburi Si Nakhon Atcha and upgraded Ban Khok Atcha to be Mueang Sangkha in 1763. In 1778, King Taksin the Great lead his troop to Vientiane and Champasak. Mueang Sangkha was a part of the king troop. When King Taksin won, he promoted the governor of Sangkha to the rank of a Phraya. In 1806 the status of Mueang Sangkha was upgraded to be a direct subordinate of the capital Bangkok. In 1828 Phraya Sankhaburi (Thong Duang) was endorsed to become Mueang Khukhan governor to replace the killed previous governor. In 1907 Monthon Isan was divided into 4 sections (Boriwen). Mueang Sangkha was under the Surin Section, together with Mueang Surin. Mueang Sangkha at that time was subdivided into 3 districts, Sangkha, Si Khonphum and Changkan.
