The village of Yang was founded in 1877 by a group of villagers led by Puean Chaiyanat (พื้น ไชยนาถ) who evacuated from Ban Muang (บ้านม่วง) in
Phibun Mangsahan. The village became a subdistrict (
tambon) under the control of "Uthai Det Udom" district (or
Eastern Det Udom, currently is
Yang Yai) in Thailand's former province, , in 1907, The newly merged district,
Det Udom was later transferred to
Ubon Ratchathani province in 1928. In 1974, Tambon Yang, together with three other tambons, including
Song,
Dom Pradit, and
Ta Kao, were split off from its affiliated district,
Det Udom, to create a new province's administrative division,
Nam Yuen district; the preparation for such an upgrade began in 1969 with the formation of
King amphoe Nam Yuen. However, one of the original tambons,
Ta Kao, was eventually split off to form a new independent district in 1996. Nine villages in the southeast territory of Yang were partitioned in 1979 to form a new tambon,
Bu Pueai; a newly established tambon was also further divided in 1988 to create
Yang Yai. Yang was divided once more in 1993, when tambon
Kao Kham was formed. Before 1996, Tambon Yang was governed by the Subdistricts Council of Yang, which was later upgraded to the
Subdistrict Administrative Organization (SAO). ==Geography==
