According to historical chronicles of Muang Yasothon, Phra Chao Voravongsa, and his followers in 2340 B.E. were migrating to settle down with the governor of Champasak.
Along the way, they stopped at Dong Phi Singh and decided to make their home there as it was found to be an appropriate site which was later named Ban Ta Singh or Muang Ta Singh. In 2357 B.E. King Rama II issued an edict to upgrade the settlement into a town. Muang Ta Singh, reporting direct to Bangkok.
The rank of Phra Rachavongsa was given to the governor. The town was subsequently elevated into a province under a Revolutionary Order No.70 on February 6,2515. The province was made up of the following districts, Yasothon, Kam Khuan Kaew, Maha Chaichana, Pa Tiew, Lerng Nok Tha and Kud Chum (all formerly in Ubon Ratchathani), and officially came into existence on March 1,2515 (1972).
