Ta Kao
Ta Kao () is a capital tambon (subdistrict) of Nam Khun district, in Ubon Ratchathani Province, Thailand. It previously was a tambon in Nam Yuen district but gained district status in 1996. As of the 2021 consensus, it had a population of 10,056 people and 3,867 households in 14 villages (Muban;  บ้าน or หมู่บ้าน), which were further subdivided into 15 administrative community groups (Moo or Mu; หมู่). Neighbouring subdistricts are (clockwise from the south) Song, Khok Sa-at, Phaibun, Khilek, Yang, and Kao Kham. History
The village of Ta Kao was founded in the early 19th century by a group of Khmer-origin settlers led by an elderly Kao (or Ta Kao); the village was then named Ta Kao in honor of the first village headman. At the early age, tambon Ta Kao was administrated from Thailand's former province,  then was transferred to Det Udom district in 1912. In 1974, Tambon Ta Kao, together with three other tambons, including Song, Dom Pradit, and Yang, were split off from Det Udom to create a province's new administrative division, Nam Yuen district; the preparation for such an upgrade began in 1969 with the formation of King amphoe (small district) Nam Yuen. In 1977, Takao's northern half, which consisted of 11 villages, was split off to form a new tambon called Khilek; a newly established tambon was later split off to create tambon Phaibun in  1982. Its southwest territory was also promoted to tambon Khok Sa-at in 1991. Later in 1996, Ta Kao and its all three mentioned descendant tambons were cut off from Nam Yuen district to creat a province's new district, Nam Khun. After independence, Tambon Ta Kao was governed by the Subdistrict Council of Ta Kao, which was upgraded to the Subdistrict Administrative Organization (SAO) in 1997, and, effective on December 13, 2013, it was later promoted to a subdistrict municipality.
